Disable XHC/XHCI devices from waking up or preventing computer to sleep or suspend

disableXHCwakeup.service

# Adapted from Ropid's post on https://bbs.archlinux.org/viewtopic.php?id=263268
#
# This solved my U-Phoria UMC204HD from preventing system suspend (sleep), causing an XHCI error of sorts. 
#
# I used journalctl --boot=-1 --grep="suspend"
# to figure out some service related to XHCI was tossing error code -16 and prevented sleep.
#
# If using systemd you just toss it in the following
# /etc/systemd/system/disableXHCwakeup.service
#
# Run sudo systemctl enable disableXHCwakeup.service
# You will likely need to shutdown/restart for this service to work
#
# !!! IF THIS DOES NOT WORK, OR INTERFERES WITH OTHER DEVICES

This solved my U-Phoria UMC204HD from preventing system suspend (sleep), causing an XHCI error of sorts.

If using systemd you just toss it in /etc/systemd/system/disableXHCwakeup.service and run sudo systemctl enable disableXHCwakeup.service
You will likely need to shutdown/restart for this service to work.
