How do I find the USB speeds o my older MAC desktop? Profiler gives me info, is there a lookup table?
Look at the USB information. It will show you the bus and the speed. If you're asking about your Mac Pro, for which there is a forum (this forum is for old, pre-G3 hardware), all the ports are USB 2.0.
Hosts moved the thread to the Mac Pro forum, in case anyone is confused by my comment.
Go to http://www.apple-history.com/, find your Mac and look for Input/Output.
