To fix those I've created a script in /lib/systemd/system-sleep/ with the following contents:
#!/bin/sh
case "$1" in
pre)
echo -n "0000:00:14.0" | tee /sys/bus/pci/drivers/xhci_hcd/unbind
echo -n "1-3:1.2" |tee /sys/bus/usb/drivers/btusb/unbind
;;
esac
case "$1" in
post)
echo -n "0000:00:14.0" | tee /sys/bus/pci/drivers/xhci_hcd/bind
echo -n "1-3:1.2" |tee /sys/bus/usb/drivers/btusb/bind
;;
esac
Of course, the values are not random and should be checked first on your machine with lspci -v and by looking into /sys/bus/usb/drivers/btusb
