Normally, I simply plug in a USB Key and it appears on my desktop. On the
Suse Linux (10.3) machine, I need to become root to write to it, but
that's a minor inconvenience.

Then I purchased an 'A Data C905' key at Canada Computers and discovered
that it would mount only as a 'read only file system'. After over an hour
of fruitless fiddling around with fstab and device permissions, I decided
(which I should have done much earlier) to try another key, (by LG). That
one mounted just fine: I could read from and write to it.

Then I tried the A Data key on a win XP laptop and a netbook running
Ubuntu Jaunty Jacalope. The key mounted fine on those machines, both read
and write.

So far as I could see, there are no posts on this specific issue on the
internet. But some posters mention keys that could not be recognized
because of a timing delay problem, some keys apparently take longer than
others to initialize. The cure in that case is to lengthen out a delay
after the device is recognized.

Has anyone else seen this type of problem?
