got into same problem and successfully solved it using a how-to found somewhere
(i can't find it again, sadly).
The problem is with usb3 drivers, all you need to do is unbind those and rebind
after resume.
0000:00:1a.0 and 0000:00:1d.0 are files found with something like ls
/sys/bus/pci/drivers/ehci_hcd/0* adjust the file /etc/pm/sleep.d
/20_custom-ehci_hcd with yours devices and suspend/resume should work.
There is still some minor flaw, the keyboard keeps blinking while the
computer is suspended, but not a big deal.
cat /etc/pm/sleep.d/20_custom-ehci_hcd
#!/bin/sh
case "${1}" in
hibernate|suspend)
# Unbind ehci_hcd for first device XXXX:XX:XX.X:
echo -n "0000:00:1a.0" | tee /sys/bus/pci/drivers/ehci_hcd/unbind
# Unbind ehci_hcd for second device XXXX:XX:XX.X:
echo -n "0000:00:1d.0" | tee /sys/bus/pci/drivers/ehci_hcd/unbind
;;
resume|thaw)
# Bind ehci_hcd for first device XXXX:XX:XX.X:
echo -n "0000:00:1a.0" | tee /sys/bus/pci/drivers/ehci_hcd/bind
# Bind ehci_hcd for second device XXXX:XX:XX.X:
echo -n "0000:00:1d.0" | tee /sys/bus/pci/drivers/ehci_hcd/bind
