Clerification: Pandora's big USB port will not work with "USB low speed" or "USB Full Speed" devices.
Slightly FTFY. Yes, it confuses me too - high speed is faster than full speed. I had to look it up on Wikipedia again - I initially thought the rest of your post had it wrong, but it turned out you were righter than I was.
Thank you for the fix, I'll go fix that in the original.
The naming is incredibly confusing and using USB 1 and USB 2 only makes it worse as USB 1 is a subset of USB 2, so many devices claim to be USB 2, but only support USB low speed or USB Full Speed. On top of all this is now USB 3 that includes USB 2 and USB1, adds "USB Ultra Speed" and new connectors
