I purchased a PCMCIA USB 2.0 Card (I paid $30 for it at a computer swap meet) so I could use my Lumenera LU075C on my HP Laptop instead of using my wife’s work laptop. It occurred to me when reading your post that the PCMCIA that I purchased can be powered from an external source (I checked the specification on the packaging), this may solve your power and speed issue. I also took the time to checkout the net and found some companies that sell USB2.0 CardBus PCMCIA Card with power adapter.
This should help you out if you attend to do most of your imaging at home like I do.

I have heard this comment before I have also seens this behaviour attributed to the cable (must be capable of supplying the power) but it is of little consolation to me as my laptop has USB 1 and I will not be changing it any time soon. I suppose I could add a USB2 PCMCIA card (would fix speed but not power issues?) or connect a (powered) USB2 hub to my USB 1 port (would fix power but not speed) and get better reliability, anyone done that? It is very annoying when if freezes - especially as I bought this gear to guide with more than for imaging - this forces me to use GuideDog rather than ASSuite which does not seem to suffer the same issues. Looks to me like ASS is a VB app and thus has performance issues (poor multitasking/single thread design).
