[Bug 446146] Re: Several Huawei USB dongle don't work with kernel 2.6.31-12.40 (2.6.31.1 update related)

I also face the same issue. I am running 2.6.31-14-generic #48 in a Toshiba R600.
lsusb shows: ID 12d1:1001 Huawei Technologies Co., Ltd. E620 USB Modem
i also get "error mounting: mount exited with exit code 32: mount: block device /dev/sr1 is write-protected, mount read-only....blah"

dmesg:
option 3-1:1.2: GSM modem (1-port) converter detected
usb 3-1: GSM modem (1-port) converter now attached to ttyUSB0
option 3-1:1.1: GSM modem (1-port) converter detected
usb 3-1: GSM modem (1-port) converter now attached to ttyUSB1
option 3-1:1.0: GSM modem (1-port) converter detected
usb 3-1: GSM modem (1-port) converter now attached to ttyUSB2
option: option_instat_callback: error -108
option1 ttyUSB2: GSM modem (1-port) converter now disconnected from ttyUSB2
option 3-1:1.0: device disconnected
option1 ttyUSB1: GSM modem (1-port) converter now disconnected from ttyUSB1
option 3-1:1.1: device disconnected
option1 ttyUSB0: GSM modem (1-port) converter now disconnected from ttyUSB0
option 3-1:1.2: device disconnected
usb 3-1: reset full speed USB device using uhci_hcd and address 3

This repeats. I also get a "notification" that GSM is
disconnected...never connected.

9.04 worked well,9.10 not so well.

usb_modeswitch is installed and working as best as I can tell....
