Hi,

There is one modem called Alfa Fly 3G. In its document, linux is not in supporting OS.
Moreover i didnt find any mode switch command in usb_modeswitch utility.
It is detected as

T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=12 MxCh= 0
D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
P: Vendor=1da5 ProdID=f000 Rev= 0.00
s: Manufacturer=HSUPA USB Device
s: Product=H21 HSUPA USB Device
s: SerialNumber=000000000000
C:* #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr=500mA
I:* If#= 0 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usbserial_generic
E: Ad=01(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=81(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms

Is there way to convert it into modem mode.

Thanks in advance.

Well, I could repeat the exact same reply as for the Haier CE100 ...

I tried this modem with configuration of HAIER modem, but it didnt work.

usb_modeswitch -v 0x1da5 -p 0xf000 -C 0xff -M 5553424312345678000000000000061e000000000000000000000000000000 -2 5553424312345679000000000000061b000000020000000000000000000000 -I

And same time kernel logs are like

Feb 28 10:50:45 (none) user.info kernel: usbserial_generic 1-1:1.0: device disconnected
Feb 28 10:50:45 (none) user.warn kernel: usb 1-1: usbfs: process 8568 (usb_ms) did not claim interface 0 before use


It seems first command(-M ) fired successfully but second command(-2) didnt work.
The output of cat /proc/bus/usb/devices is same as before(showing storage mode).

So i need your help. Can u give me what can be done next to resolve this.

First:
Check if you have the "NeedResponse" parameter set to 1.

If that is the case, try to leave away the first message. Set "MessageContent" to the second string.

If all this doesn't bring any good results, you need to sniff on the Windows driver.
