I have an unstable usb-device that needs to be reset every five minutes. So far, I manually unplugged it which is rather annoying. I found out that it's possible to reactivate it by unbinding/rebinding, so that it can be rescued by this script: (I can parse the path from lsusb -t)
echo '1-1' > /sys/bus/usb/drivers/usb/unbind
echo '1-1' > /sys/bus/usb/drivers/usb/bind
This script can onlty be executed by root, but I'd like to integrate the calls into my application (C++ binary). Running everything as su sounds like an overkill and I hope that there is something like a group that has this ability.
