Once it works for root, it shouldn't be hard to get it to work for
a specific user.
1) What group does /dev/usb/dc2xx0 belong to?
2) Does group have sufficient permissions? (I don't know exactly
what permissions might be needed, but if you give to group the
exact same permissions that owner has, I would expect it to work.)
3) Make sure your user belongs to this group. ('groups' command to
check, 'adduser' to include a user into a group -- see man pages for
more details.)
.... I see Andrew has just replied to your question too. I agree
about permissions, but would guess it probably is a better idea
*not* to change ownership of /dev/usb/dc2xx0. ....
