Re: USB: driver for CM109 chipset

["Shaun Jackman" <sjackman@gmail.com>]

I am testing your cm109 driver with my Genius G-Talk USB phone. It
identifies itself as a cm109 device (0d8c:000e C-Media Electronics,
Inc.). I compiled and loaded the cm109 module. However when I plug the
phone in the, the usbhid driver grabs the device rather than the cm109
driver. The following snippet is from /proc/bus/usb/devices and shows
the Class/Subclass/Protocol 3/0/0 device is nabbed by the usbhid
driver. Why isn't the cm109 driver grabbing the device?

Thanks for writing the driver, and I hope I can get it to work!
