Hi Forest, > The LG LGSBWAC92/TWCM-K505D/EAT64454801/EAT64454802 (it goes by many > names) is a combo WiFi/Bluetooth module that's used in several models of > LG TVs. It uses the MediaTek MT7668AUN, which is already supported in > btusb, but this device has a non-MediaTek VID:PID pair so to get it to > work we just need to add it to the list of devices to probe. > > Device from /sys/kernel/debug/usb/devices: > > T: Bus=09 Lev=02 Prnt=02 Port=00 Cnt=01 Dev#= 6 Spd=480 MxCh= 0 > D: Ver= 2.10 Cls=ef(misc ) Sub=02 Prot=01 MxPS=64 #Cfgs= 1 > P: Vendor=043e ProdID=3109 Rev= 1.00 > S: Manufacturer=MediaTek Inc. > S: Product=Wireless_Device > S: SerialNumber=000000000 > C:* #Ifs= 3 Cfg#= 1 Atr=a0 MxPwr=100mA > A: FirstIf#= 0 IfCount= 2 Cls=e0(wlcon) Sub=01 Prot=01 > I:* If#= 0 Alt= 0 #EPs= 3 Cls=e0(wlcon) Sub=01 Prot=01 Driver=btusb > E: Ad=81(I) Atr=03(Int.)
