Hi,

first, it is now also possible to pass additional quirks to the usbhid 
module using the 'quirks' parameter.

$ grep -1 CMEDIA drivers/hid/usbhid/hid-quirks.c
#define USB_VENDOR_ID_CMEDIA            0x0d8c
#define USB_DEVICE_ID_CMEDIA_CM109      0x000e

--
        { USB_VENDOR_ID_CIDC, 0x0103, HID_QUIRK_IGNORE },
        { USB_VENDOR_ID_CMEDIA, USB_DEVICE_ID_CMEDIA_CM109, HID_QUIRK_IGNORE },
        { USB_VENDOR_ID_CYPRESS, USB_DEVICE_ID_CYPRESS_HIDCOM,
HID_QUIRK_IGNORE },

Adding a HID_QUIRK_IGNORE entry to the blacklist is sufficient. Could you 
please double check that this patched driver really binds to the device?

If so, could you please compile with CONFIG_HID_DEBUG enabled and modprobe 
the usbhid module with 'debug=1' parameter and send me the kernel output?
