Exclamation Huawei E1550 USB Modem Unresponsive in 11.2


My machine is running on a dual-boot Windows Vista/openSUSE 11.2 scenario. I have been trying to get my Huawei E1550 to work on Linux for the past few days trying numerous methods suggested in other forums from people with the same problem, but I have not produced any fruitful results.

Plugging in the USB modem results in Linux detecting it as a CD-ROM. I have installed usb_modeswitch in attempt to switch it to a modem, but Linux still fails to recognize it. Windows Device Manager and lsusb both give ProductID=1001 and VendorID=12d1 connected to USB1. I'm guessing since Windows detects the correct IDs, the Linux versions should also be correct. In any case, I ran usb_modeswitch with the Default IDs for /etc/usb_modeswitch.conf, which gave 0x1446 as the ProductID, not 0x1001. Upon running usb_modeswitch, the product ID could not be found so the program fails and quits asking if it's connected (and it is).

Just to test, I also ran wvdial which unsurprisingly did not detect the modem and could not send the init strings.

All commands were done using root privileges. Also note that when after usb_modeswitch is run and upon plugging in the USB, NetworkManager pops up near the tray saying "attached" but still shows the device as a CD-ROM.

Please help! My provider is Dialog and I am living in Sri Lanka if that is of any use.

See farbird's post in that

Did you eject the device first?

Agreed. These devices appear as cdrom devices to the system initially. You might have to issue something like

eject /dev/sr1
