P.S. I am using NetworkManager 0.9.2.0, Arch Linux, XFCE

Update: Test on Xubuntu 11.10 Live CD

I have just tested it under Xubuntu.

  • After booting I have plugged-in USB modem.
    • Modem was immediately recognized by the system and start working
  • I have unplugged it and plugged it back.
    • Modem was recognized and working.

I would say, that dmesg output from Xbuntu looks similar to one from Arch.

Any Ideas?

You can boot a current live-cd of a well tested distribution that uses binary packages (like Fedora or Ubuntu) to check if your problem is Arch specific. –  maxschlepzig Apr 13 '12 at 18:15
    
@maxschlepzig I have made a test under Xubuntu. Looks like it works. See above. –  Anton Prokofiev Apr 15 '12 at 18:12
