However, the pre-production samples are found in the wild, and this lack of support is causing problems for users of such samples. It is therefore necessary to support both variants. Matching on both interfaces 0 and 1 is not expected to cause any problem with either variant, as only the QMI function will be probed successfully on either. Interface 1 will be rejected based on the HID class for the production variant: T: Bus=01 Lev=03 Prnt=04 Port=00 Cnt=01 Dev#= 16 Spd=480 MxCh= 0 D: Ver= 2.10 Cls=ef(misc ) Sub=02 Prot=01 MxPS=64 #Cfgs= 2 P: Vendor=413c ProdID=81d7 Rev=03.18 S: Manufacturer=DELL S: Product=DW5821e Snapdragon X20 LTE S: SerialNumber=0123456789ABCDEF C: #Ifs= 6 Cfg#= 1 Atr=a0 MxPwr=500mA I: If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.)
