Using kernel 2.6.12: USB flash drive (san-disk cruzer micro) Copy FROM drive is normal and quick; copy TO drive is amazingly slow. (30 minutes for 50K file). Used same configuration as for 2.6.11.11. Cured by going back to old kernel. Sorry I can't give better report. Thank you. Joe Sevy __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Also, linux-usb-devel is the better place for this if you have a more detailed report. thanks, greg k-h ^ permalink raw reply [flat|nested] 7+ messages in thread

I knew that someone will try to implicate ub here, but you? Consider two things: #1 Joe's kernel reads and writes and sharply different speeds, while ub is uniformly slow #2 It's a regression in 2.6.12 -- Pete ^ permalink raw reply [flat|nested] 7+ messages in thread

I knew that someone will try to implicate ub here, but you? Heh, sorry, I didn't really pay attention for the time ammounts, only that he reported things slower. You are right, ub isn't _that_ slow at all, I use it all the time on some of my devices just fine. thanks, greg k-h ^ permalink raw reply [flat|nested] 7+ messages in thread

Ub actually gets terribly slow when partition size is odd (for both reading and writing). I even have a patch for it, but it's yucky.

Symptoms seem similar to this: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=159269 Try 2.6.13-rc2, it would be a valuable data point. -- Pete ^ permalink raw reply [flat|nested] 7+ messages in thread
