LinuxQuestions.org - mobile getting switched off by USB

Hi, sounds like you need to switch modes for the usb modem.

usb_storage or usbserial

Check this out...

Code:

# /etc/usb_modeswitch.conf

#

# Last modified: 2008-05-06

#

# Configuration for usb_modeswitch, a mode switching tool for controlling

# flip flop (multiple device) USB gear

#

# Triggers the switching of several known UMTS modems from storage device mode

# ("ZeroCD TM" for use with MS Windows) to modem (serial) device mode

#

# Detailed instructions and a friendly forum on the homepage:

# http://www.draisberghof.de/usb_modeswitch



# Note: Timing of execution might be an issue (less so with recent

# versions of the tool). See homepage!



# What it all means:

#

# * DefaultVendor

# * DefaultProduct

#

# This is the ID the USB device shows after having been plugged in.

# The tool looks for this; if not found -> no action.

There is also a command rmmod, but you'll have to check on it's modern-day usage.

I use a huawei e220 usb 3g modem and had similar problems at first.
I have an example somewhere...(as soon as I find my reference, I will post it here.)

For now, Glenn

Try this, rmmod -w usb_storage

The -w , allows all using the module to continue, but no new modules.

if the module is using usb_storage and not usbserial power management.

Hope this helps, remember to read up on the rmmod command first!

Also, lsusb and lspci may give more details.

Cheers, Glenn
