This is pretty much irrelevant. The USB hub is not interested in the  
host OS, nor the functions of the peripherals connected to it. Any  
USB hub should be Mac, Windows & Linux-compatible, but it is possible  
that a cheap one could cause (latency on the USB bus? and) the  
spinning beachballs you describe.

Do you get the slow-downs when the hub is disconnected? If so then  
the hub is irrelevant, and the fact that slow-downs started when it  
was introduced is surely coincidence. I detest Lexmark printers &  
would try & isolate that to ensure it is not the guilty party; I  
frequently see printing problems associated with Lexmark's drivers  
under Windows XP, and if they cannot serve their principle market  
properly, what hope do Mac users have? (ps: take it back & get a Canon)
