[wplug] usb memory sticks / non-root?

[Brandon Kuczenski]

I'm using a usb memory stick to transfer files with a Windows computer.  I 
was thrilled that:

# mount /dev/sda1 /mnt/usb/mem 

seemed to work great! Unfortunately, 

# chmod a+w /mnt/usb/mem

did not work -- it said permission was denied (and so only root could copy
files to the memory stick).  Using mount with -o users didn't seem to
help.  I found at least one webpage saying it was not possible for
ordinary users to have read/write privileges on usb memory sticks in Linux
.. can you folks confirm this?

thanks,
-Brandon
