ERROR: Removing 'pl2303': Operation not permitted
ecar@ecar:~$ sudo rmmod pl2303
ecar@ecar:~$ sudo rmmod usbserial

Only then It's not enough. You also have to remove ehci_hcd / uhci_hcd / ohci_hcd.the device will be powered off (unless the method described in the link given by Jiri Slaby powers the device off, too).


ecar@ecar:~$ modprobe usbserial
FATAL: Error inserting usbserial
(/lib/modules/2.6.17-11-386/kernel/drivers/usb/serial/usbserial.ko):

(reverse-i-search)`mod': cd backup_modules/

cd backup_modules/? Where do you keep your modules?
