[PATCH] option: add Quectel UC15, UC20, EC21, and EC25 modems

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add Quectel UC15, UC20, EC21, and EC25.  The EC20 is handled by
qcserial due to a USB VID/PID conflict with an existing Acer
device.

NOTE: The UC20, EC21, and EC25 should also get a corresponding qmi_wwan
patch but I don't have that lying around at this time.
