USB O2 UMTS Stick huawei E161 (ttyUSB21) HSDPA Modem

i do not have a solution to this yet.

links probably the same „modeswitching“ is installed… modemmanager

modemmanager - D-Bus service for managing modems
modem-manager-gui - GUI front-end for ModemManager / Wader / oFono <- was manually installed


usb-modeswitch - mode switching tool for controlling "flip flop" USB devices
usb-modeswitch-data - mode switching data for usb-modeswitch

is installed.
