Can't connect to huawei E220
« on: February 16, 2009, 03:29:11 am »

I used to have my huawei E220 G3 USB modem working nicely on VL-5.9 - on an ancient Gateway Solo 2150 notebook.  I recently upgraded to VL06.9-RC4.

Now when I connect my device, the /dev/ttyUSB{0,9} devices temporarily appear then disappear.  The logs suggest that the device is being repeatedly connected and disconnected:

..etc.

Does anybody have any suggestions?  I've tried the huaweiAktBbo and usb_modeswitch binaries recommended on various forums, and I've got the usbserial and option modules loaded - all with no success.  I'm wondering if the 2.6.27.12 kernel doesn't agree with my ancient hardware.
