Comment 43 for bug 17881

Hi,
I have a similar problem (at USB2.0)
I'm a newbie at linux.

Here are my trials:
(use a folder contains 102 files / 61.1MB)

Normal:
write trials, hangs at 2nd trial.

cat 64 > /sys/block/sdb/device/max_sectors
write trials, hangs at 1st trial.

modprobe -r ehci_hcd
(force to work at USB1.1)
write trials: 3x, OK - slow
read trials: 3x, OK - slow

modprobe ehci_hcd
(reuse the module after removed)
write trials: 10x, OK - fast
read trials: 10x, OK - fast

Boot without the flash memory pluged
modprobe -r ehci_hcd
modprobe ehci_hcd
Plug the flash
write trials: 5x, OK - fast
read trials: 5x, OK - fast

Boot without the flash memory pluged
Plug the flash
write trials: hangs at 4th trial.

Is it module/driver loading problem?
