Got it.
I'll update my wireshark/libcap to avoid packet truncation and try capturing again.

After updating libpcap I see my wireshark dump as follows from link:
http://pastebin.com/4FPMbxXX
It looks almost similar to SniffUSB one.
I suspect that I connected the usb-device to the virtualbox machine near the frame#165.
I even used 55534243123456780800000080000a4a010000100000000800000000000000 and 55534243123456781200000080000603000000120000000000000000000000 messages for usb_modeswitch but had no success.
Do you have a chance of taking a look at the packets dump to check if there is anything to point out to correct message(s) I should use?
PS. The driver was completely installed before I connected device to windows. After connecting a device Linux displayed
Code: Select all
Sep 13 21:34:07 t500 kernel: [17349.438132] usbcore: registered new interface driver cdc_acm
Sep 13 21:34:07 t500 kernel: [17349.439242] cdc_acm: v0.26:USB Abstract Control Model driver for USB modems and ISDN adapters
in its log.
I can provide the whole dump starting from installing a driver in windows if it could help.
Thanks in advance.

Thanks for the wireshark log, it provided some interesting insights. I only could respond just now because I have been travelling.
Now, could one of you AirPlus owners try the following manual command? To check if it does anything good just run dmesg afterwards and see if "cdc_acm" was activated (like after switching in Windows).
Code: Select all
usb_modeswitch -I -v 1edf -p 6003 -u 2

after running this command got device /dev/ttyACM0 usable as modem, working fine.

I think that "sense error" is what we see in the Windows log as well, where it takes around 10 seconds for the device to arrive at the modem mode. It
might help to detach the storage driver first; try:
Code: Select all
usb_modeswitch -I -d -v 1edf -p 6003 -u 2

I'm glad it finally works ...
BTW, how long does it take to switch with the last posted command ?
