In certain kernel configurations where the cdc_ether and option drivers are compiled as modules there can occur a race condition in enumeration. This causes the option driver to enumerate the ethernet(wwan) interface as usb-serial interfaces. usb-devices output for the modem: T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 5 Spd=480 MxCh= 0 D: Ver= 2.00 Cls=ef(misc ) Sub=02 Prot=01 MxPS=64 #Cfgs= 1 P: Vendor=1e2d ProdID=0055 Rev=00.00 S: Manufacturer=Cinterion S: Product=AHx C: #Ifs= 6 Cfg#= 1 Atr=e0 MxPwr=10mA I: If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.)
