I'm using a huawei E220 modem and occasionally it doesn't work and I
must unplug and plug it again, run the scripts connection to make it
works again.
how can I unplug an plug an USB modem via software?

The other problem is that this device is recognized like a cd rom
although I have patch my kernel 2.6.17. here is the var/messages:

Sep 28 12:53:41 ecar kernel: [17179613.972000] Vendor: HUAWEI
