As I can't use the SDDR-31 either, it would be a dramatic improvement if
I could get that working. But I'd most like to find a USB-2 reader that
works, because the files my camera writes are huge...
This is not good, because -71 is a low-level protocol error. 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.
It's a desktop, not a laptop. My current (brand new) mobo is an ASUS
A7V880 VIA KT880. It also has a brand new AMD 3200/400 CPU and brand
new RAM. And I've tried two different power supplies, just for kicks.
There are no hubs involved, I plug the CF readers directly into the
onboard USB.
So yeah, I've already run so far out of ideas that I've gone down the
"replace absolutely everything" path. Hell, the *disks* are only a few
months older than the rest of the machine. The only other peripheral
plugged into the machine at all is the video card (Nvidia 5700 Ultra).
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.
Ok, what other info would help?
BTW, I should note that it is possible to use a passive PCMCIA-CF
adapter.
I've used those succesfully in laptops, and consequently (a few years
ago) I tried to get two different models of PCMCIA bay installed in my
desktop machine to avoid USB entirely, but that was an even bigger
disaster.
