ALinuxUser, Xiaofan Chen's example was unbinding the usbhid driver via
the /sys/bus/usb/drivers/usbhid/unbind control file -- yours is using
/sys/bus/usb/drivers/usb/unbind instead. You probably have to use the
control file that corresponds to the driver your device is using. (Check
lsusb -t
I am sorry to necrobump, but I don't get it.
$ sudo echo -n '2-3' | tee -a /sys/bus/usb/drivers/usb/unbind
Produces, on my system, this: 'tee: unbind: Permission denied'.
Similarly if I have used 'su' to obtain root:
# echo -n '2-3' | tee -a /sys/bus/usb/drivers/usb/unbind
2-3tee:
That's ok :)

Thanks, but this is not a bug. To do what you want to do, you need to do
the following:
echo -n 1-7:1.0 | tee -a unbind
The reason for this is that the command sequence you are using is
actually 2 commands. The first command is sudo echo -n 1-7:1.0, which
is ran as root and echos the character
You are absolutely right and your method works.
Sorry for the false alarming.
