This is a simple Linux service to automatically reset one or more
devices whenever your system resumes from sleep. The devices are
specified as sysfs
BUS ID paths in the configuration file /etc/rebind-devices.conf. It
works by writing the BUS ID of the device to the unbind and bind
files pertaining to the associated
device driver. Use lspci, lsusb -v, etc to find the BUS ID path of a
device you want to reset, so you can add that BUS ID to your
configuration file. Your system must be using
systemd.
I use it to reset the USB controller on my external dock whenever my
system resumes, to fix a faulty USB keyboard that otherwise does not
restore. I used lspci | grep USB to determine it's BUS ID.
The latest version and documentation for this utility is available at https://github.com/bulletmark/rebind-devices.
