Hello-

Looking to provide support under Linux for our device which implements
a USB virtual  serial port using the Communications Device Class.

The device enumerates and communicates correctly under Windows XP, 
and shows up under lsusb -v command as:

Bus 005 Device 005: ID 0c6a:0005

        bInterval               0
Device Status:     0x0000
  (Bus Powered)

However it does not show up without the -verbose option.

Trying to load the usbserial module to activate the device results in the 
following error:

FATAL: Module vendor=0x0c6a not found.

Can anyone provide assistance in how to troubleshoot why Linux is 
not happy with this USB device ?

Thank you,
