Hello, I bought a yota w8 (vid:1bbb pid:025e), and it can not be switched under Linux.
I captured the packets exchanged between the modem and the host after plug in the modem
using Bus Hound. It seems that the modem switched to 1bbb:0195, but I cannot find the
exact switch command. I suspect that the "mode sense" and "mode select" has done the job
but I cannot replicate the progress using
usb_modeswitch -v 0x1bbb -p 0x025e -M "1a001c00c000" -2 "151000001800"

Please help me!!!

This is the bus file before mode switch:

T: Bus=01 Lev=02 Prnt=02 Port=00 Cnt=01 Dev#= 4 Spd=480 MxCh= 0
D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
P: Vendor=1bbb ProdID=025e Rev= 2.32

The BusHound log is a bit strange when I try to follow cmds out and the corresponding reply to it but I think the dongle will switch with:

usb_modeswitch -v 0x1bbb -p 0x025e -M 55534243123456781800000000000615100000180000000000000000000000

Thanks for your kindness reply...

I used the following command and it works fine....

usb_modeswitch -v 0x1bbb -p 0x025e -M 55534243123456788000000080000606f50402527000000000000000000000

That's even better since it is a commonly used command for devices from the 1bbb vendor, it will be included in the next issue of usb_modeswitch data package.
