K3b permissions issues.

In the shop I wrote a CD, when I came home I wrote a dual layer DVD, and for
some days after I was busy writing various media.
Then one time I tried to burn a CD (actually the Dapper Beta 2 image) and
couldn't. I found if I invoked K3b as root it was OK. But this problem
definitely occurred with both DVD and CD writing. It's something that just
seemed to creep in after some time.... and I cannot think of anything in
particular that could have invoked it.
K3b setup tool should in theory set the correct permissions for the device but
for some reason it lists it as being on sg1 whereas the actual cdrecord
program thinks the writer on sg0, hence the problem with permissions.
If I look under /dev/ sg1 does indeed have the cdrom group, but sg0 remains as
group root, which is not very helpful.
The thing that really gets me is why it worked perfectly and then broke after
some time. What really gets me is that I have 2 images of my computer as
backups. These were taken sometime before I ever got the new writer, I tried
both of these backups and both were the same with having incorrect
permissions. That means that it couldn't have been any update causing this
problem.
The only thing I can think of is that in the shop I connected the drive
directly to a USB port on the laptop, and I since changed it so it was
connected to a USB 4-way hub and this caused the device node to change.
However if I connect it directly to its own USB port it still retains the odd
permissions....
