With the E398 hardware it seems that HUAWEI becomes a little bit more
sophisticated with the interface enumeration. Protocol numbers are now
used to identify the usage of certain ports.
T: Bus=01 Lev=02 Prnt=02 Port=00 Cnt=01 Dev#= 63 Spd=480 MxCh= 0
D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
P: Vendor=12d1 ProdID=1506 Rev=00.00
S: Manufacturer=Huawei Technologies
S: Product=HUAWEI Mobile
C: #Ifs= 7 Cfg#= 1 Atr=c0 MxPwr=500mA
I: If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=01 Prot=01 Driver=option
I: If#= 1 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=01 Prot=02 Driver=(none)
I: If#= 2 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=01 Prot=03 Driver=(none)
I: If#= 3 Alt= 0 #EPs= 1 Cls=ff(vend.) Sub=01 Prot=09 Driver=(none)
I: If#= 4 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=01 Prot=08 Driver=(none)
I: If#= 5 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage
I: If#= 6 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage
At this moment only one port is bound, because the driver focuses
on Prot=01 (MODEM), but also Prot=02 (PCUI) and Prot=03 (DIAG) should
be bound by the driver.
AT^SETPORT=?
1:MODEM
2:PCUI
3:DIAG
4:PCSC
5:GPS
6:GPS CONTROL
7:NDIS
A:BLUE TOOTH
B:FINGER PRINT
D:MMS
E:PC VOICE
A1:CDROM
A2:SD
The AT^SETPORT command lists the HUAWEI definitions for port usage.
