3GB of RAM can be a problem. Try iommu=soft. .. but in such case rmmod/insmod of usbhid would not help...
If rmmod/insmod usbhid helps, and system is fully working after that, then it is probably usb problem....
Is your problem fixed after latest RTC findings? If not, try to debug insmod/rmmod of usb, first. If that does not work, it is unlikely suspend/resume will.
