rndis_host: support Novatel Verizon USB730L (63ba395c) · Commits · 戴 / test

Treat the ef/04/01 interface class/subclass/protocol combination used by the Novatel Verizon USB730L (1410:9030) as a possible RNDIS interface. T: Bus=01 Lev=02 Prnt=02 Port=01 Cnt=02 Dev#= 17 Spd=480 MxCh= 0 D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 3 P: Vendor=1410 ProdID=9030 Rev=03.10 S: Manufacturer=Novatel Wireless S: Product=MiFi USB730L S: SerialNumber=0123456789ABCDEF C: #Ifs= 3 Cfg#= 1 Atr=80 MxPwr=500mA I: If#= 0 Alt= 0 #EPs= 1 Cls=ef(misc ) Sub=04 Prot=01 Driver=rndis_host I: If#= 1 Alt= 0 #EPs= 2 Cls=0a(data ) Sub=00 Prot=00 Driver=rndis_host I: If#= 2 Alt= 0 #EPs= 1 Cls=03(HID ) Sub=00 Prot=00 Driver=usbhid Once the network interface is brought up, the user just needs to run a DHCP client to get IP address and routing setup. As a side note, other Novatel Verizon USB730L models with the same vid:pid end up exposing a standard ECM interface which doesn't require any other kernel update to make it work. Signed-off-by:
