Many many THANKS for your post.
I have a Plumax IEEE/USB Case coming in this week. It also uses the Prolific ChipSet. Your using the CDR3 combo case with B3EC firmware. Am I correct ?
Does it work in both USB and Firewire Modes ?
Have you tried B3HC Firmware ?
The reason I'm asking, is that, in reading boards all over the world, it appears that B3HC is a problem Firmware release. I see postings dealing with non detected drive via Windows not only with externals but also different brands of motherboards (internal drive).
I know you POSTed questions on the BenQ Global Forum. I put some details under your post. I also did my own POST. I guess BenQ didn't like what I had to say and it was deleted.
I will let you and everyone else know the outcome when the new case comes in. I think I will only use B3EC and not B3HC.
