commit 3c841d54b63e4446383de3238399a3910e47d8e2 upstream.
T99W651 is a RNDIS based modem device. There are 3 serial ports
need to be enumerated: Diag, NMEA and AT.
Test evidence as below:
T: Bus=01 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=0489 ProdID=e145 Rev=05.15
S: Manufacturer=QCOM
S: Product=SDXPINN-IDP _SN:93B562B2
S: SerialNumber=82e6fe26
C: #Ifs= 7 Cfg#= 1 Atr=a0 MxPwr=500mA
I: If#=0x0 Alt= 0 #EPs= 1 Cls=ef(misc ) Sub=04 Prot=01 Driver=rndis_host
I: If#=0x1 Alt= 0 #EPs= 2 Cls=0a(data ) Sub=00 Prot=00 Driver=rndis_host
I: If#=0x2 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=40 Driver=option

I: If#=0x5 Alt= 0 #EPs= 1 Cls=ff(vend.) Sub=ff Prot=70 Driver=(none)
I: If#=0x6 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=42 Prot=01 Driver=(none)
0&1: RNDIS, 2:AT, 3:NMEA, 4:DIAG, 5:QDSS, 6:ADB
QDSS is not a serial port.
