What's up with USB thumb drives on OS4?

"I have know idea?. I bought it second hand. It's an original 600mhz G3 AmigaOne. I'll have to read up on what the fixes were."

That sounds like one of the old AmigaOne SE's.  They are pretty much a lost cause as far as USB goes.

Sadly that applies across the board for A-Ones, since they all share the same chipset and associated issues.

The Teron motherboard was never meant to be anything other than a proof of concept/evaluation board. It should never have shipped as a finished product to the public.

No.  Thats not entirely true.  The XE has issues that can be somewhat fixed.  The Micro's were better off but have other limitations.  The SE is pretty much unfix-able.  

I have a Micro and USB works fine except for the occasional corruption which is caused by an OS bug.
