[Bug 288964] Re: sudo does not work with unbinding usb interface from usbhid driver
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 output.)

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: /sys/bus/usb/drivers/usb/unbind: No such device # ls /sys/bus/usb/drivers/usb 1-1 1-1.2 1-1.6 2-1 bind uevent unbind usb1 usb2 usb3 usb4 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/288964 Title: sudo does not work with unbinding usb interface from usbhid driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sudo/+bug/288964/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

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 sequence you specified. The second command is unbind, which re-directs the output, but this is not running as root. ** Changed in: sudo (Ubuntu) Status: New = Invalid -- sudo does not work with unbinding usb interface from usbhid driver https://bugs.launchpad.net/bugs/288964 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

You are absolutely right and your method works.
