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:

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,
