Their devices claim to support the erroneous data reporting, but don't actually support the required commands. So blacklist them and add a quirk. < HCI Command: Read Default Erroneous Data Reporting (0x03|0x005a) plen 0 > HCI Event: Command Status (0x0f) plen 4 Read Default Erroneous Data Reporting (0x03|0x005a) ncmd 1 Status: Unknown HCI Command (0x01) T: Bus=02 Lev=02 Prnt=08 Port=02 Cnt=01 Dev#= 10 Spd=12 MxCh= 0 D: Ver= 2.00 Cls=e0(wlcon) Sub=01 Prot=01 MxPS=64 #Cfgs= 1 P: Vendor=10d7 ProdID=b012 Rev=88.91 S: Manufacturer=Actions S: Product=general adapter S: SerialNumber=ACTIONS1234 C:* #Ifs= 2 Cfg#= 1 Atr=c0 MxPwr=100mA I:* If#= 0 Alt= 0 #EPs= 3 Cls=e0(wlcon) Sub=01 Prot=01 Driver=btusb E: Ad=81(I) Atr=03(Int.)
