problems with usb mass storage flash memory

Hi,
I had/have problems with my usb flash memory devices (a Verbatim 32MB usb
stick and a NOKIA 5510 Mobilephone/mp3 Player)
I am able to mount both devices and copy small files (<100KB) to them. A
subsequent sync/umount works. If I copy larger files (>=1MB) the cp works
but a sync/umount takes forever and my syslog gets filled with SCSI errors.
(tested under 2.6.5, 2.6.5-mm6, 2.6.6-rc1 and 2.6.6-rc2 with the
anticipatory io scheduler as well as the cfq)
After appling the patch from
http://marc.theaimsgroup.com/?l=linux-usb-devel&m=108238832020721&q=raw
things are working with the Verbatim 32MB usb stick. The NOKIA is still
broken.
Under linux 2.4.25 both devices are working (with the uhci as well as the
usb-uhci module)
I think kernel 2.6 uses the uhci driver so my log output under 2.4 was
created using this one.
Here is the output from patched 2.6.6-rc2:

The NOKIA 5510 seems a bit strage. A fdisk /dev/sda and a "p" (print
partition table) under 2.4.25 shows:
Disk /dev/sda: 63 MB, 63946752 bytes
8 heads, 32 sectors/track, 487 cylinders
Units = cylinders of 256 * 512 = 131072 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 489 62576 6 FAT16
Partition 1 has different physical/logical beginnings (non-Linux?):
phys=(0, 1, 1) logical=(0, 0, 32)
Partition 1 has different physical/logical endings:
phys=(488, 7, 32) logical=(488, 7, 31)
The creation of a new partiontable seems to work (a fdisk "w" complete
without errors) but a subsequent fdisk /dev/sda and a "p" prints the same
as before.
Any Ideas?

Andreas Weber
