I’ve got a 2500a in one machine which works great. So, I went and bought a 2510A for another. Nero keeps telling me the device is “in use” so it can’t access it. Saw thread that indicated NEC wants Nero 126.96.36.199, which isn’t out yet, for the 2510. I’ve tried a few of the older suggestions for the “in use” problem, with no affect. I find it interesting that the drive is list as “NEC DVD_RW ND-2510A" No other device has that "” in front the name.
