I'm a new user of Ubuntu, and connect to internet via Huawei e1550 dongle (USB modem). I also have a Windows OS like a second one (dual boot) on my laptop. So yesterday I login to Windows, do some stuff .. Then re-login to Linux and dongle started working again. So I do some stuff, then suspend the system and go sleeping.
This morning I open laptop, but it was no connection. I try to re-plugging dongle, reboot the Linux, suspending, but all that stuff was useless. So I reboot it once again, go to windows, connect to internet, then again reboot to Ubuntu and now dongle work again.
So, why is that strange? And what should I do to be able use dongle in Ubuntu without previously loading windows?
lsusb output for device when working as a modem is like that:
Bus 003 Device 002: ID 12d1:1001 Huawei Technologies Co., Ltd. E169/E620/E800 HSDPA Modem
when I re-plugging it, it stop working again and lsusb input change to this:
Bus 003 Device 012: ID 12d1:1446 Huawei Technologies Co., Ltd. E1552/E1800 (HSPA modem)
So it makes me once again reload to Windows and then go back to Ubuntu to be able to connect to Internet.
