I have the same problem in Ubuntu 12.04 Precise AMD64 under Unity.
The modem connects only if I disconnect it and plug it off then on.
Let's add that the modem does not switch to modem mode in 12.10 Quantal at all.

What do you mean by uid root? sudo -s ?
if I type : sudo modprobe -r usbserial
Then I get an error:
Fatal: module usbserial is in use.

right?

This problem *may* be related to bug #990337 - driver loading failed
there because of an issue with finding modprobe on the system. AFAIK
this is limited to the C wrapper, so if it is the same problem it is
Ubuntu-only.
To be sure, we would need to see a log for the mode switching.

Hi,
I have the exact same problem.
The solution is:
* Insert usb modem Huawei E173 into usb port
* As uid root:
modprobe -r usbserial
modprobe -v usbserial vendor=0x12d1 product=0x1c08
This works for me.
