It seems like this device has same vendor and product IDs as G2K
|
|
devices, but it has different number of interfaces(4 vs 5) and also
|
|
different interface layout which makes it currently unusable:
|
|
|
|
usbcore: registered new interface driver qcserial
|
|
usbserial: USB Serial support registered for Qualcomm USB modem
|
|
usb 2-1.2: unknown number of interfaces: 5
