USB-Storage, slow speed with sync option

[Stefan <gentoopower@yahoo.de>]

Hi folks,

I'm not sure if this is the correct list for my problem. So bare with me.

When I copy files to my USB 2.0 Stick , my transferspeed are horrible in
case I mount the device with sync option, the rates are around 50KB/s,
doesn't really matter how big the files are.
If I don't mount with option sync, then the speeds are as expected a
couple of MB/s

I don't think this is the default behaviour, right?

Anybody got an idea what could be wrong?

Filesystem is vfat.
I tried with different kernels and a live cd(knoppix), currently I use
kernel 2.6.13.
Motherboard is an NFORCE 4 based one:

0000:00:02.0 USB Controller: nVidia Corporation CK804 USB Controller
(rev a2)
0000:00:02.1 USB Controller: nVidia Corporation CK804 USB Controller
(rev a3)

USB Info shows the device using ehci_hcd module

Thanks in advance, Stefan
