I'm a bit late responding but maybe someone else can use this: 

We are using the Cypress drivers on Windows 7 64 but there is a trick. During boot up using the F8 key you get to a screen similar to the XP safe mode screen. An added option is "suspend signed driver enforcement". You have to do this each time you boot up and pressing F8 late enough that you are past getting the option of selecting the boot drive but before Windows starts requires practice. Once we discovered this CyConsole and the rest of the examples work without issue.

ezusb.sys is not compatible with windows 7. It is not compatible with any of the 64-bit OSes. You will have to move to CyUSB.sys for win7 and 64-bit support.

http://www.cypress.com/?rID=34870

When i plug in my module with the FX2 windows says "unknown device"

please help!

 Have you modified inf file for Windows 7 64bit? Document CyUSB.pdf in C:\Cypress\Cypress Suite USB 3.4.7\Driver describes how to modify inf file for different OS, go through it.  What is the VID/PID being displayed in Devicemanager?

Thanks

Prajith

USB\VID_04B4Q&PID_8613&REV_:001

here are the .inf and .sys files I want to install. See the attached zip file.

When i right click on the inf file to install, windows gives me a notification: "installation method not supported"

 Hello I would really appreciate any input that proves to be useful I am trying to install a Laser engraver for my brother never have I come across an issue ever installing anything but  I get EZ-USB FX2 under other devices and seems there is no driver anywhere for this their own cd and instructions contradict themselves. He has a Win7 64bit  I see you post  a Cypress program but what I am still confused is how do I get the driver or find it  is there an INF already in there somewhere that I am just not seeing that has the needed information to enable the install please help. Thank you my email if easier is Csi_corp@hotmail.com thank you guys once again

If you have EZ-USB FX2 kit, the CD provided along with it will have ezusb.sys, if I am not worng. ezusb.sys is not compatible with win7 64 bit OS as people have been saying in this thread. You will have to upgrade to cyusb.sys

Thanks

 Hi,

I believe you are trying to use LAser engraver and as you plug in it shows up as FX2 in device manager. What is the VID/PID with which it comes up? I believe you may have to contact the vendor itself to get the right driver for this product, since it is not necessary that the have designed it to work with CyUSB.sys. What doe sthe instruction manual of the product say regarding the driver for this product. Neverthless you can give it a try binding to CyUSB.sys and see if it works in case they are just using a renamed version of this driver.
