[hpsdr] Re Ozy Problem

[Geoff]

Hi Guys,
	The Ozy that I am using has the C8 part. It works pretty well on my dual boot 
laptop (Kubuntu/XP) but not very well at all on my desktop XP box. The desk 
top tests with a DPC latency as bad as 4000+ uS, I haven't tested the laptop 
(if it works don't stuff around with it :-) ).
