I believe I found the problem. We have had some momentary power
fluctuations. To get the computer to recognize a flash drive returned to
the USB port I was RESTARTING the CPU. I decided to power completely
down (SHUTDOWN) and even unplug the AC for a short time. Upon restarting
Tumbleweed, I found that inserting and removing flash-drives returned to
normal. Should of thought of this from my Windoze experience - When all
else fails power down, wait, and restart. Carlos was right, it was a
machine issue probably caused by momentary power interruptions.
Thanks for the help
