I need driver for windows 7 for device cy7c68013a-56pvxc.

Is there driver for this device?

After installing SuiteUSB 3.4 - USB Development Tools for Visual Studio, you can find the CYUSB.sys driver in the below directory.

C:\Program Files\Cypress\Cypress Suite USB 3.4.1\Driver

This driver supports 32 bit and 64 bit versions of Windows XP,Windows Vista and Windows 7.

For windows 7 you will find in the C:\Program Files\Cypress\Cypress Suite USB 3.4.1\Driver\wlh

Hello

I wanted to use this driver , win 7 but said there was no driver in this directory

I modified the. inf file to vid to 04b4 and pid to 8613

regards

Hi ,

You need to edit the file in the directory where your driver is , i.e. suppose you sre using win7 32 bit then this is the path "C:\Program Files\Cypress\Cypress Suite USB 3.4.2\Driver\bin\wlh\x86" if you are using win7 64 bit then "C:\Program Files\Cypress\Cypress Suite USB 3.4.2\Driver\bin\wlh\x64", both these folders have inf files depending upon your OS add the vid/pid info in the correct inf file and point to it when asked for driver.

I am attaching a inf file for 64bit win 7 , if you want for 32bit then modify the vid pid under ;for x86 platforms.

Thank you for the answer
I edit the file and I tried the x64 version and x86

but Windows 7 said he does not find a driver in this directory
I did the test without the jumper with VID 04b4 and PID 8613
with jumper the vid/pid is 0925 and  3881

What is the problem ?

您好

我用上述的方法做过了，可是不可以实现，在xp系统下可以用，但是在win7下找不到设备

希望能给我点建议

谢谢

hello

i have done by your process in win7 ,but the computer said unkonw device.......

so can you give me some advice

thanks

Hi Pitt,

What is the exact error message you're seeing?

Regards,

Anand

I have the same problem; if it’s like my case he gets the very descriptive message:

“Windows could not find driver for your device.”

My thread is: http://www.cypress.com/?app=forum&id=167&rID=50852

I have the same problem with window 7 x 64

the usb driver is not loading

got your copy of cyusb1.inf

pointed back to this file to install the driver .

Windows has stopped this device because it has reported problems. (Code 43)

when i try to update the driver windows comes back with a message

"windows has determined the driver software for your device is up to date"

Unknown Device

if i click on driver details i get

" no driver files are required or have been loaded for this drvice"

I am stuck now cant get this to work is there any other way to get the driver to load?

Hello,

I've tried everything, but I can´t get it work. Right now, I get that the driver has been found and it's instaled,  but Windows stopped him.

Erorr code 10.

I have been trying to start my developement for about 10 days :-( I'm stuck !!


regards

M0DMJ,

In cyusb1.inf there is a ; before the VID_04B4 statement. ; is a comment line in inf file. Remove that ; and modify the corresponding lines to your VID/PID and it should work fine.

Anand

Gonmalo,

Are you using the board with a firmware? if so which firmware?

Regards,

Anand

Hi,

of course I made all the modifications to the .inf file to get to this point. I don't know wich firmware, I'm trying to connect to the chip for the first time.

greetings

Gonmalo,

Are you using FX2LP DVK (CY3684) or a custom  board. What is the VID/PID being displayed in device manager for the device?

Regards,

Anand

After installing SuiteUSB 3.4 - USB Development Tools for Visual Studio, you can find the CYUSB.sys driver in the below directory.

C:\Program Files\Cypress\Cypress Suite USB 3.4.1\Driver

This driver supports 32 bit and 64 bit versions of Windows XP,Windows Vista and Windows 7.

For windows 7 you will find in the C:\Program Files\Cypress\Cypress Suite USB 3.4.1\Driver\wlh

按照这种方法，把里面相应的文件拷贝到应用程序的Drivers中去，还是不会在win7 x64环境下使用驱动。。。

Hi    :-)

maybe it's a good idea to delete my posts. But maybe it's a better idea keep them, for someone who could be as unlucky as me!!

Always check on your USB cable, this was the problem :-( I changed it for a new cable and ... perfect it worfs perfect.

PS: its a custom board, that I bougth in China

I have a board with CY7C6013A. When I plug into my PC Window 7 , PC  always try to install the driver for my previoues installed driver for AN2131SC.   Is there anyway to install the new driver ?

Are you using Windows 7 32-bit or 64-bit OS? Is your driver for AN2131SC a signed driver?

Regards,

Anand

my pc is win7 64bit 128pinCY7c68013 can be use ,but 64pin CY7c68013 can be used and is a "Unknown Device"

I want to know why,how can I deal with this problem.

 Hello Sciencefuture,

I could not understand your exact problem. Can you detail the same.

Gayathri

I bought a cy3864 advanced development board, try work in windows 7 64bits system,but can not solve the driver problem, can not find it anywhere i tried.

help

Cheers,

Anand

same problem.

edit cyusb.inf in  ulh/x64, modyfied vid&pid, uncommoned. copy to windows/inf

copy cyusb.sys to windows/system32/driver

system say 'conn't find corresponding file

I used 3864 develop ezusb deve kit

system said:

Windows found driver software of your device but encountered an error attempting to install it.

Cypress USB generic driver (3.4.7.000)

the system connot find the file specified.

 That is because the inf file will say the driver is in the same folder as the driver file. Don't do the copying.

Keep both inf file and driver file in same folder and try.

Only if you use a installer it will take care of specifying the drivers are in the specific system tolder.

Regards,

Anand

solved thanks.

I'm using window 7, 64xbit operating system.  I have inserted the following and still it did not work.

;for x86 platforms
[Device.NTx86]
VID_04B4&PID_8613.DeviceDesc%=CyUsb, USB\VID_04B4&PID_8613

;DMM measurement

VID_0F22&PID_F020.DeviceDesc%=CyUsb, USB\VID_0F22&PID_F020

 Hi,

[Device.NTx86] is for 32 bit processor. Since yours is a 64bit systems, you need to write the VID/PID under [Device.NTamd64]. Please find attached inf file. I have added the two entries for you in the appropriate section. Please check it out. 

Regards,

Gayathri

Thanks, I tried that and it does allow to me to install without digital signature, but my device manager still show the yellow exclaimation mark

for x64 platforms
[Device.NTamd64]
;VID_XXXX&PID_XXXX.DeviceDesc%=CyUsb, USB\VID_XXXX&PID_XXXX
VID_04B4&PID_8613.DeviceDesc%=CyUsb, USB\VID_04B4&PID_8613

; DMM
VID_0F3F&PID_F010.DeviceDesc%=CyUsb, USB\VID_0F3F&PID_F010

; Scope
VID_0F3F&PID_F022.DeviceDesc%=CyUsb, USB\VID_0F3F&PID_F022

Pleas advise,

thanks

 Hi,

In the entries that you have posted in the previous response, I see % symbol missing at the very start of the entry. It should be as below:

%VID_0F3F&PID_F010.DeviceDesc%=CyUsb, USB\VID_0F3F&PID_F010

When you are binding using the Install driver Wizard, what does it show at the end? Does it give some warning/ error message ? Please check VID/PID being shown in the Device manager (right click on device -> Properties -> Details tab). Also check what is the message displayed in the Device Status coloumn in the Device manager (right click on device -> properties -> General tab). Please attach screenshots of both.

Did you use the same inf file that I had attached in the previous response? Just change its to CyUSB.inf (change extension from txt to inf). Just wanted to ensure this.

Regards,

Gayathri

I tried on my other Win7, AMD processor, 32-bit operating system. device driver installed succesfully.  However, I would like to have it work on Win7, Intel processor, 64-bit operating system.  Attached are the snapshots after implementing changes per your advice.

Thanks

 Hi,

[Device.NTamd64] is meant for 64-bit processors with architecture other than intel itanium architecture. So, it should be [Device.NTia64] is for Intel itanium architecture processors. Please make the change in the inf and try.

Regards,

Gayathri

Hi,

thanks for your tremendous help. Please see the attached inf file. I have modified .inf file to work with intel 64xbit, window 7 operating system and it still did not work.  Please advise if you find out something within the code.

thanks again,

TuDo

Hi,

       Attachment is missing.

Sorry, here is the attachement.

Wow...sorry, I forgot to change .inf to .txt

thanks

Tudo

 Hi Tudo,

It seems CyUSB.sys does not support Intel Itanium architecture. Sorry for the misguiding info.

Regards,

Gayathri

 Hi Tudo,

Just wanted to confirm. Is yours a Intel Itanium processor ? If it is of any other architecture (even if it from Intel like Intel i5), inf with [Device.NTamd64] will work. Please verify the same.

Regards,

Gayathri

My processor is Intel(R) Core(TM) i7-2720QM CPU @ 2.2GHz

Window 7 Professional, 64-bit operating system

Thanks for your quick response

Hi,

 See this http://www.cypress.com/?app=forum&id=167&rID=59606

Dear all i have a problem with binding my device with windows 7

first of all my device in the device manager doesnot appear under universal serial bus controller

it appears under something called human interface driver/usb input device

then when i update the driver to bind my device with the .inf driver

i get this message

the folder you specified doesnot contain a compatible software driver for your device. if your folder contains a driver make sure that it works with windows 32-bit system

what can i do now at the control center i have an EZ-usb appearing but when i try to download the program it tells me please select an fx2 device from the tree

i would appreciate if any one helps

thank you.

 Hi Hammouda,

Which USB device are you using? Please clarify.

It is coming under the HID devices in device manager since the PC is recognizing that as HID device, and not as a generic USB device. This info will be passed to the PC in the descriptor information. In the descriptor, we would be specifying the class information. If the code mentioned there is of HID class, then it will bind to the Windows HID driver by default.

Please detaiil the device that you are using, so that we can help you.

Regards,

Gayathri

Dear Gayathri

my device is a board containing cy768013a-56 and a 128k eeprom connected to it , you will find the schematic attached ......

and i have noticed that it binds to the pc automatically under HID so what can i do.......?? i need to bind the device manually so

as to start downloading the program via control center.......

 Hi Hammouda,

I did not go through your schematic fully. But at the first glance, I noticed that you have a jumper J3 which can be used to disconnect  the EEPROM from FX2LP. So initially connect your board with J3 left open. Now, the device will come up under "USB devices" in device manager, as "NO-EEPROM" or "EEPROM Missing". If it prompts to bind the driver, point it to the correct CyUSB.inf with VID/PID entry of 0x04B4/0x8613. (More about binding with driver can be found at "C:\Cypress\Cypress Suite USB 3.4.x\Driver\CyUSB.chm" aftter installing SuiteUSB from http://www.cypress.com/?rID=34870).

Once it appears as "NO-EEPROM" device in device manager, it will also show up in CyConsole/ Control Centre. Now select the device from Treeview in Control Centre. Put jumper J3 back. Select PROGRAM FX2 -> 64KB EEPROM and then browse to the location having the iic file that you need to download to the EEPROM. Click Open and this will download the firmware to EPPROM. Following this, RESET your board/ Unplug and plug in again. This will cause the renumeration of device running the new firmware. It will again prompt for the driver. Now point to the CyUSB.inf as you did before. But now, you need to ensure that VID/PID corresponding to the one in the firmware must be entered in CyUSB.inf.

I think, EEPROM already contains some firmware that corresponds to HID class firmware. Please check this out and let me know if it works out.

Regards,

Gayathri

Ok Gayathri

i have removed j3 and now my device is with no eeprom.......

but the windows device manager had put it under something called unknown device..... and when i tried to bind the driver with the cy.inf it didnot give me the past error but i have a new error  now while binding it

it says " windows ecountered a problem installing the driver software for your device "

"windows found the driver software to your device but encountered an error while installing it"

"Cypress EZ-USB with no eeprom"

"The configuration registery key is invalid"

and i have also a prewarning before pressing the last next button to insall it it say

"device is not digitally signed"

what does that mean to ??

am sorry it said "the driver is not digitally signed"

Ok there are some new things happend here and they are all strange

first of all the cy.inf file must be edited by a text viewer and we must change the xxxx part in the vid/pid to put the known values for my device

ok i made sure i did that part

second of all i knew from past conversations in this forum that i have to remove the (;) mark before each line to make the line active ok i did that

all that i did in the cy.inf file in the "x86" file under "wlh" and it gave me the error of windows has encountered an error during installation thing ok........

so i gave it a try to use the cy.inf file under the folder "x86" under the folder "w2k" this time which i have not defined the vid/pid for and guess what......!!!!!!!!!!

it worked .........very strangeeeee. 

but another problem happend now that after i dowloaded the iic file to the eeprom and i opened the bulklook application it says that it doesnot see the bulkloop device.....well that is expected because what is installed is the fx2 with no eeprom

when i put in the eeprom it sees it as a cy device under usb generic and everything is ok but identified as "with no eeprom device"

but when i put the eeprom back its not recognized and again put under unknown devices part.......

so it will obviously wont work with the bulkloop application because it doesnot see the device WITH THE EEPROM

so i thought of a different thing why shant i download the .hex file of the bulkloop directly to the ram .......with no eeprom

i did that but the result was still the same

PLEASE GYATHRI TELL ME WHAT ON EARTH IS HAPPENING HERE SEEMS LIKE ALOT OF STRANGE THINGS TOGEATHER.

The "No EEPROM" part is the string that is used in the inf file. FX2LP doesn't inform the host whether there is a EEPROM connected or not.

If your board is being detected with EEPROM and comes up as unknown device when EEPROM is not connected. Then I suspect there might be board issues. Are you following the schematic review checklist in http://www.cypress.com/?docID=30633 and layout guidelines specified in http://www.cypress.com/?docID=32407

it has just worked alright

i had a problem removing the ( ; ) mark from alot of unneccessary lines and paragraphs..........

i just removed the ( ; ) from the line only  under my platform or system category (X86) and it worked just fine........

sorry for the disturbance and thank you.

 Cool..Glad that you posted the issue..

Regards,

Gayathri

my board use cy7c68013-128AXI. it was detected in XP 32-bit with old CyConsole. But in win7 64-bit by SuiteUSB3.4.7 i have some errors like "USB device Not Found". in device manager under the detected Unknown Device i recieve "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"

let me talk on this image
