I will test the solution mentioned by @s-breedveld of applying: "pci=nomsi iommu=soft" and report if this helps.

In my case this is a bluetooth mouse which disappears after suspend.

A dmesg output indicates:

[ 3380.759427] xhci_hcd 0000:00:14.0: xHC is not running.
[ 3380.774604] xhci_hcd 0000:00:14.0: xHCI host controller not responding, assume dead

[ 3381.059735] usb 1-5: USB disconnect, device number 5

A power-down is usually required to fix this, a reboot does bring the device back to life.
