If people could post whether or not CFQ is enabled and whether they still have the slow usb problem that would be great info:

Task: View Current Disk scheduler

Assuming that your disk name /dev/sda, type in a terminal:

cat /sys/block/sda/queue/scheduler

Copy and paste the output of the above command.

My system shows:

noop anticipatory [deadline] cfq

Which means my system (9.10 Karmic Koala beta with no updates) is using deadline by default and I am currently not experiencing the problem. I was experiencing the slow USB transfer speeds in 8.04 Hardy Heron and 8.10 Intrepid Ibex.
