Reading is ok (ca. 1 s for 2,3 MB).=20 It doesn't matter if trying as root or normal user. I only have to unmount the stick and remount it without "sync" and writing is fast. That means I write something on the stick (ok it's buffered) and=20 then I type "sync" as command and after 1 s it's done (LED from usb stick turned off and data were written). All this starts with kernel 2.6.13, 2.6.12 was ok. I'm using 2.6.13 (not >)! If it's solved in an newer Kernel, please ignore this email.
