Hi,

Is there any updates since 2016 ?

I have the same issue for firmware freshly compiled in latest SDK.

In Ubuntu 18 (Linux ubuntu 5.3.0-51-generic #44~18.04.2-Ubuntu)  "modprobe usbserial .."mentioned above just quits silently with no result.

Regards,

Leonid

Hello Leonid,

Please refer to this KBA Adding Communication Device Class Interface to FX3 Firmware - KBA229099 and check if the firmware modification is correct and composite device enumerates fine.

If only the CDC interface is not binding to the driver please try programming usbuart example firmware, in the SDK (path: ...\Cypress\EZ-USB FX3 SDK\1.3\firmware\serialif_examples\cyfxusbuart), to FX3 and check if the driver is binding to the CDC interface. In usbuart example, the FX3 enumerates as a CDC device.

As mentioned earlier to check if the device enumerates and binds to the appropriate driver correctly lsusb command can be used.

Hello Leonid,

Can you please brief the issue you are facing.

Is the device USB CDC and UVC device not being detecting in Ubuntu?

What does the lsusb command output?

Thanks,
