    The USBVideoClassBulk sdk example isn't working on ubuntu 14.4

    roman.tcharny_2243706

      I've tried to run the USBVideoClassBulk example from the sdk as is. It is compiled and uploaded to CX3 evaluation board, but I can't see the video device on my linux machine.

         

      There is some problem with usb descriptors, cause I get this message in dmesg:

         

      [71795.430285] usb 3-2.2: Product: FX3

      and the "lsusb -v" for cypress device seems to be cut in th middle.
