I've finally had time to do some digging, and the regression is caused by: b963801164618e25fbdc0cd452ce49c3628b46c8 USB: ehci-hcd unlink speedups ..that was introduced in 2.6.27. Reverting this change in 2.6.29-rc5 makes the card work happily again. I don't know enough about USB protocols to speculate on whether there may be a better fix, but hopefully someone cleverer than me can get to the bottom of the problem? Cheers David
