Subj : USB 3 Issue?

Hi Folks!

Have been having sort of a vaguely defined issue with USB devices on my 
computer.  Sometimes, so yes, not consistent, plugging anything into 
either the USB 2 or USB 3 front panel ports will cause the system to 
lock/freeze.  Oddly thumbdrives (USB sticks) are 95% of the time fine 
while plugging in a USB DVD device will but not always cause a lock up.

Last night was copying some files to thumbdrives (4 GB, USB 2.0), 
inserting them to a powered USB 3.0 hub.  Started off fine, then the Hub
or rear panel port froze; reboot to clear.  OK for a while, then 'loss' 
of the thumbdrive, sometimes other devices on the hub were seen (lsusb).
Later looking around found sometimes the USB camera was detected by 
Cheese, sometimes not, sometimes the picture was freeze-framed.  Yes, 
lots of inconsistencies.

Tried swapping out the Hub for another USB 3.0 powered one; same 
inconsistencies, so appears the Hub is OK but maybe not the port.

This morning tried something: powered off the Virtual XP portion -- it 
detects the devices attached to the Hub (and also those attached 
elsewhere); all not captured.  Copied six thumbdrives without a problem.

Suppose you want some of the specs:  Ubuntu 18.04, Oracle's VM 
VirtualBox....

TIA!
