I have done my best to research this, but have not found a solution.
After a new Arch installation on a new machine (Dell Precision T3400) I am unable to change the permissions (even as root!) on files once they are transferred to the usbstick (a Code 1 error message is returned). Other operations, such as copying, moving and deleting occur as usual. I have also noticed that as soon as files are transferred to the USB stick, the permissions get changed (but not the ownership), as if whatever is reading the stick is also changing the permissions.
It is not the stick -- the same stick performs normally on every other computer I use it on.
fstab: /dev/sdc1 /mnt/usbstick vfat rw,user,auto,sync 0 0
(basically the same as on 3 other Linux machines I use, all running Arch).
When mounted, sdc1 has ownership root:disk. I have added myself to the disk group. /mnt/usbstick has myself as the owner.
Not a major problem, just slightly irritating.

Hi,
FAT does not support file-permissions.
I guess that's the problem
Probalby you should switch to an unix-fs or ntfs (if you need win machines to access this stick without installation additional tools / drivers)

Thanks, Pheon --
I just noticed I made a mistake in giving my fstab line, it should be:
/dev/sdc1 /mnt/usbstick vfat rw,user,noauto,sync 0 0
(so "noauto" instead of "auto" in the mount options)
As I indicated, this is not a USB stick problem (same stick works just fine on other machines) -- also, in my attempts to troubleshoot this, I changed the filesystem on the USB stick to VFAT -- previously, it was whatever the default is when it comes out of the factory, and at that time the fstab line looked like:
/dev/sdc1 /mnt/usbstick auto rw,user,noauto,sync 0 0
Same situation, i.e. changing the filesystem did not affect the problem in any way.
Any other ideas?

I use Lanrat's suggestion here: http://bbs.archlinux.org/viewtopic.php?id=46944
It might help in solving the problem...

Hi Zenlord -- this looks interesting and more in the direction of where I was thinking the problem might be lurking.
thanks!
