SubjectRe: software unplug and plug USB
I also have a mobile phone connected, a gps and a keyboard, i do the
following:


ecar@ecar:~$ lsmod | grep usb
usbserial 29928 1 pl2303
usbtouchscreen 8708 0
usbcore 130304 7
libusual,pl2303,usbserial,usbtouchscreen,ehci_hcd,uhci_hcd
ecar@ecar:~$ rmmod pl2303
ERROR: Removing 'pl2303': Operation not permitted
ecar@ecar:~$ sudo rmmod pl2303
ecar@ecar:~$ sudo rmmod usbserial
ecar@ecar:~$ modprobe usbserial
FATAL: Error inserting usbserial
(/lib/modules/2.6.17-11-386/kernel/drivers/usb/serial/usbserial.ko):
Operation not permitted
(reverse-i-search)`mod': cd backup_modules/
(reverse-i-search)`modpro': sudo modprobe ehci_hcd
ecar@ecar:~$ sudo modprobe usbserial vendor=0x12d1 product=0x1003
ecar@ecar:~$ lsmod | grep usb
usbserial 29928 0
usbtouchscreen 8708 0
usbcore 130304 6
usbserial,libusual,usbtouchscreen,ehci_hcd,uhci_hcd

but only when I unplug and plug manually, the modem starts up ...
Because of that i wanted to unplug/plug via scripting (software way)
