My driver works fine in Windows XP, but fails in Win7. Window shows "This device cannot start.(code 10)".

I use CY7C68013-128AC. My computer has 2 system XP and Win7 ( 32-bit ).

Driver outputs the below result.  After the driver sends SET CONFIGURATION, return from IoCallDriver

USBD is  wrong (c0000001).

Firmware is very simple.

 {           ...............;

        case usb_SET_CONFIGURATION:           

             Configuration =  Xbyte[aSETUPDAT+2];           

             break;       

            EP0CS |= bm7

}

I would really appreciate some hints about this issue. Thanks!

1. What is the driver being used?

2. c0000001 is just operation unsuccessful as per http://msdn.microsoft.com/en-us/library/cc704588%28v=prot.10%29.aspx

Hi, Anand,

Thanks for your answer.

The driver is similar to \Cypress\USB\Drivers\ezmon\ezusbsys.c

c0000001 is operation unsuccessful, but this information is still not enough for me to figure out  the problem.

Thanks

Steven

ezusb.sys was not tested with Vista/7 and from what I'm aware of it will need modification before you can get it to even load in Win 7..

When device manager says code 10 it means it doesn't have enough information to point the exact reason behind the error http://support.microsoft.com/kb/943104

Migrating to CyUSB.sys would be a good idea. Is it possible to migrate to CyUSB.sys or is the effort of migration significant?

Hi, Anand,

I did some test.  My driver is Xvpusb.sys. 

If I rename Xvpusb.sys to cyusb.sys and overwrite \system32\drivers\cyusb.sys. It works in Win7. Cypress USB Console can find my device as "Cypress USB Generic Driver (3.4.7.000)".

If I rename cyusb.sys to Xvpusb.sys and overwrite \system32\drivers\Xvpusb.sys.  It doesn't work in win7. Even in XP, it occasionally recognizes my device. Most of time shows "This device cannot start. (Code 10) ".

I don't know if you can show me what is the difference between ezusbsys.c and the souce cyusb.sys in those modules:

Ezusb_CallUSBD, Ezusb_ConfigureDevice, Ezusb_SelectInterfaces.

Thanks!

hi,
i am using USB3FPGA and successfully installed  driver(cypress usb
generic driver 3.4.7000 ). i am using CYSUSB CONTROL CENTER & USB CONSOLE
for my communication with the USB3FPGA board and it works.
After i used
option " program FX2---->small EEPROM " of the USB control center and loaded
an example  "cystream.iic " file in it. After loading it , the device is not anymore detected
by the control center.i have also reinstall the driver but then driver installation
wizard shows the error msg now as :
"cypress USB Generic Driver
(3.4.7000)
This device cannot start.(Code 10) "

i have also checked the VID & PID which are correct.
1)Is anything happened to eeprom therefore its contents changed etc?
2) how can i access eeprom ,as device is not detected any more?
3)which file and changes i have to adopt to make the device detectable?solution?

Thanks
