USB_ModeSwitch

Hi,

I have a Virgin Mobile 3G key 5832 and the USB switch is not working correctly.

I am using latest USB_ModeSwich 1.1.8 and latest date (from 20110705), running Ubuntu 11.04.

Before the switch the key is identified as 0x12d1:0x1446.

I saw that the config file exist, but it's not working.

After sniffing, I found the product id after switching (1401) a correct message:
55 53 42 43 00 00 00 00 00 00 00 00 00 00 00 11 06 00 00 00 00 00 00 00 00 00 00 00 00 00 00

If I modified current 12d1:1446 an add 1401 to the TargetProductList and replace the message, the dongle switch correctly and I can use it.

How can we handle this?

I do not want to change the MessageContent, else others 0x12d1:0x1446 keys will no more working.

Thanks for your help,

Bertrand.

What do you mean with "it's not working"?

Does it stay with the ID "12d1:1446" ?

Or does it change ?

Hi,

Sorry, you're totally right.

So with current version of 12d1:1446 conf file, the device swith and here are the information:

T: Bus=02 Lev=02 Prnt=02 Port=02 Cnt=01 Dev#= 10 Spd=480 MxCh= 0
D: Ver= 2.00 Cls=ef(misc ) Sub=02 Prot=01 MxPS=64 #Cfgs= 1
P: Vendor=12d1 ProdID=142d Rev=01.00
S: Manufacturer=Huawei Incorporated
S: Product=HUAWEI Mobile Connect
S: SerialNumber=1234567890ABCDEF
C: #Ifs= 5 Cfg#= 1 Atr=80 MxPwr=500mA
I: If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
I: If#= 1 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage
I: If#= 2 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
I: If#= 3 Alt= 0 #EPs= 1 Cls=02(commc) Sub=06 Prot=ff Driver=(none)
I: If#= 4 Alt= 0 #EPs= 2 Cls=0a(data ) Sub=00 Prot=00 Driver=(none)

2 tty are published, /dev/ttyUSB0 and /dev/ttyUSB1, but none of them can be opened to send/recv AT command.

If I change the 12d1:1446 conf file, with the Message content I have describe, the device switch with those information:

T: Bus=02 Lev=02 Prnt=02 Port=02 Cnt=01 Dev#= 8 Spd=480 MxCh= 0
D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
P: Vendor=12d1 ProdID=1401 Rev=01.00
S: Manufacturer=Huawei Incorporated
S: Product=HUAWEI Mobile Connect
S: SerialNumber=1234567890ABCDEF
C: #Ifs= 4 Cfg#= 1 Atr=80 MxPwr=500mA
I: If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
I: If#= 1 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage
I: If#= 2 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
I: If#= 3 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=option

And in this case, 3 tty are published and can be opened to send AT command.

Thanks for your help,

So, if you use the current "official" version of the config file, ttyUSB0 is not accessible ? Did you try with "minicom" ?

This would be very bad. If this is indeed confirmed, we would have to lay it on Huawei's door. They assured me that the configuration with the differing switching command would work with all their devices ...

Hi,

Excatly, I have use GTKTerm and not Minicom, and I cannot send AT command.

I will try minicom, but I don't think tht it will make any difference.
