Can't change permissions to make file executable on USB stick

I have an 4gb usb stick with the files to be written to my 16gb uSD card.

I have a rcn-ee script “setup_sdcard.sh” to format the sdcard, expand and copy the files to the uSD card. The script is supposed to be executable is not and chmod ugo+x filename doesn’t work to make it executable. Also it appears that the uSD card is not writeable, again chmod doesn’t work to fix the problem. I am logged in as root. so it is not a failure to use sudo.

What do I need to do to make it work?

Thanks,
Alan

What filesystem is your USB drive formatted as? Do you have some specific errror messages?

The USB stick is formatted FAT32. From my reading I understand that FAT32 does not respond to chmod or chown. But that still leaves the question of how to setup angstrom to accept desired permissions.

I did find out that forking another shell with the script as its argument (bash setup_sdcard.sh options) allowed it to run.
