I am experiencing the following problem:
My umts-stick (ID 12d1:1001 Huawei Technologies Co., Ltd. E169/E620/E800 HSDPA Modem) isn´t recognized at boot/reboot if it is already connected to the PC. And I mean: it isn´t recognized at all, not even as mass-storage-device.
It doesn´t appear to be a modeswitch-problem because lsusb doesn´t list the device at all.
Yet as soon as I disconnect the stick physically (if PC is already running) and then reconnect it it´s recognized immediately (lsusb-entry is “HSDPA Modem”) and I can
establish an internet connection.
The very problem is discused here: https://askubuntu.com/questions/419659/mobile-broadband-stick-sometimes-not-detected-at-all .
But I couldn´t find a solution that works for me.
Does anyone know hat could be done about it?
Thnaks a lot in advance.
