it doesn't work for me
I just did "turn off the composite device of the 3G dongle" tutorial and still can't connect by 3g dongle.
1 - found the COM port (COM15)
2 - started putty and connected with the port COM15
3 - did ATI command and got some information about the dongle
4 - wrote
AT^U2DIAG=0 and got
OK message (see that while you write the command it doesn't appear on the console, screen still black with a green square)
5 - close putty and go to TF.
Just power up the TF, wait for whole process being started, then connected the 3g dongle. It still to blink in blue every 3 seconds.
When the LED displays blue and is blinking once every three seconds, this means that the dongle is attempting to register onto a 3G network.
By the way, I can't save any APN into APN List and actually can't connect to 3G network.
Any suggestions?!?

tried the instructions, got everything working and putty gives out this:
ati
Manufacturer: huawei
Model: E1823
Revision: 11.825.03.10.55
IMEI: xxxxxx(deleted the number here...)
+GCAP: +CGSM,+DS,+ES
OK
at^u2diag=0
COMMAND NOT SUPPORT
AT^U2DIAG=0
COMMAND NOT SUPPORT
tried the the command in big and small letters - you can see the result.
Did you type space bar after insert ^ symbol ??? If not the command appears to be ATÛ2DIAG=0 instead of AT^U2DIAG=0
It's a little hard because you can't see the command while you're typing, right?!
