# HOW TO:
# 1) Copy this file to /usr/local/bin/usb_reset.sh
# 2) make it executable: sudo chmod +x /usr/local/bin/usb_reset.sh
# 3) Create new service: sudo nano /etc/systemd/system/usb_reset.service
# 4) Paste the code from the first Gist comment below
# 5) Execute: sudo systemctl daemon-reload
# 6) Execute: sudo systemctl enable usb_reset.service
# 7) Put PC in sleep and wake PC up
# 8) Test if it works (check the log: journalctl -u usb_reset.service)

VENDOR="1b1c"
PRODUCT="1bc0"

# To find vendor and product strings:
# execute: lsusb
# Example output: Bus 003 Device 004: ID 1b1c:1bc0 Corsair CORSAIR K70 MAX RGB
# vendor:product = 1b1c:1bc0

for DIR in $(find /sys/bus/usb/devices/ -maxdepth 1 -type l); do
  if [[ -f $DIR/idVendor && -f $DIR/idProduct &&
        $(cat $DIR/idVendor) == $VENDOR && $(cat $DIR/idProduct) == $PRODUCT ]]; then
    DEVICE=$(basename $DIR)
    echo $DEVICE > /sys/bus/usb/drivers/usb/unbind
    # sleep 1
    echo $DEVICE > /sys/bus/usb/drivers/usb/bind
  fi
done

File: /etc/systemd/system/usb_reset.service

[Unit]
Description=Reset USB device on resume
After=suspend.target

[Service]
Type=oneshot
ExecStart=/usr/local/bin/usb_reset.sh

[Install]
WantedBy=suspend.target

Explanation:
this script just re-binds the selected keyboard when the system exits the suspend (sleep) state. Usually, a user would do this manually, so this script just automates the process. It is not a perfect solution, but it works every time and for all USB keyboards.
Tested on Fedora 40 and Corsair K70 Max keyboard.
