Dear all,

I have a problem regarding the USB communication to the Xylo board.
I installed the driver which are provided by KNJN and used the FPGAconf app and also one of the test tools of KNJN. All works fine.

But now the problem start by using the API from Cypress.
I downloaded the Cypress Suite USB 3.4.1 and I'm not able to find the Xylo board with every demo programm (and also the USB Control Center of Cypress) doesn't find the board.

Is there any help you can provide to us to solve this problem?

That's because KNJN boards use a GUID different from Cypress (even though the driver is the same).
Looks at the .inf file of both distributions to see that.

I have the same problem with saxo-L board (FX2 USB), using Cypress CyUSB.dll (.net version).

After the board is connected and driver loaded (with KNJN supplied .inf file), I try to find the device using C# call:

devs = new USBDeviceList(CyConst.DEVICES_CYUSB);

there is no device found in the list.

Am I missing something? Please help.



P.S. I followed steps in this post. It's still not working.

The problem is that the GUID used by KNJN for the CyUSB driver is different from the one used by Cypress.

Check the CyUSB.inf file from both the KNJN and Cypress packages to see the GUID used.

Check the CyUSB.inf file from both the KNJN and Cypress packages to see the GUID used.

While using CyAPI.lib (the C/C++ language interface), there is the function call: CCyUSBDevice(_,_), where GUID can be specified. (As can be seen in the example file supplied by KNJN)

But for CyUSB.dll (.NET library), One can use (correct me if I'm wrong):

dev = new USBDeviceList(CyConst.DEVICES_CYUSB)

to return a list of USB devices using the CyUSB.sys device driver.

My question is that why my Saxo-L board doesn't show up in that list?

Finally, I found the trick after searching the web for a whole day.

Let me post my cyusb.inf file, in case someone meet the same trouble
