It got fixed in one of the update kernels. I have no idea whether it was fixed accidentally or on purpose, however.

WinXP has a weird little message that pops up near the lower-right corner of the screen, when it runs into the equivalent of Linux's -71 errors (something about device failure or something like that, I think). In fact, if you're consistently getting two -71 errors under Linux, you might see the message appear, quickly disappear, then quickly reappear again under Windows. If you're getting a stream of -71 errors, then the Windows error may appear and disappear intermittently, perhaps in an attempt to drive you mad. ;) BTW, even if the card readers seem to work initially under Windows, the same falls-apart-after-a-few-hours behavior that you're seeing under Linux could also happen under Windows. (I've only seen a -71 error situation once. In that case, the Windows equivalent happened too, and IIRC the computer's manufacturer decided to replace the motherboard.) -Barry K.
