Yes, I meant 2.6.14. I tried the stick on a 2.6.11 desktop and it doesn't even come close to working (ep0 timeouts), but I think that may be due to old buggy 1.1 controller. > Also, please do consider taking BCP for the platform and moving _that_ > to 2.6.15.

As a side note, I traced the frames when connected to an XP machine. It NAKs the READ_CAPACITY there also, and XP gives up after a few NAKs on the second attempt. But eventually does work. It sounds like I need to verify operation with 2.6.14+ before considering any other changes, right? For my 2.6.9 needs, I'll stick with the short SD_TIMEOUT.
