Usually it is called by things like a bitstuffing violation, a missing token, etc. I cannot speculate what causes it, but every component has to be excluded by replacement. We can exclude readers now, so it leaves motherboard chips and traces, cables, possibly a hub, and most especially any power supplies involved. Sometimes it happens when people connect external VGA to a laptop, go figure! (I am not saying this is your problem, obviously). I know who I am dealing with, Jamie, but for the list archives: DO NOT exclude two articles at a time. If you replace the laptop, leave all cabling, hubs, and the reader, in place. To be frank, it is possible for the software to report -71 for a bad reason, when it is confused. Once we excluded everything else, with the computer itself, it's time to look at UHCI root hub handling. We'll take it from there. > "Eratically" means that generally they would work immediately after > I rebooted the machine, and I could plug/unplug them right after > that, and they'd continue working; but if I tried to use them again > a few hours later, the only way to make them work would be to reboot > again.

This is very interesting, but I don't think I can act upon this section of your report, especially that it appears to relate a past experience. Let's concentrate on -71s. BTW, I should note that it is possible to use a passive PCMCIA-CF adapter. I have one of those as well, and it works great. The only reason I used SDDR-31 is that my only PC Card slot was often used by a wireless card. Eventually I got used to it. Also, in older distros and kernels it was required to stop and start pcmcia services when you plug the thing, and USB always was 100% hotplug, at least in theory. -- Pete
