Vendor is HP. Opening the box did show that the CD-Writer is
indeed an IDE device. Thus US_SC_8020 seems to be more
appropriate subclass.

Yes, mostly.

No, I have only OHCI interfaces at home. (E.g. Alpha has
an OHCI type card, others are older PCs, and have none..)
USB disconnect/reconnect didn't resolve the problem.
Felt like the device (which has its own power feed)
went crazy, and thus simple reconnect wasn't sufficient.
(that "feeling" was based on partial data return from
reconnected device.)
I am not at the office, and could try that gadget here
wit UHCI, returning to the topic after system reboot..

We shall see. I am going away for a week - more gravity assisted
"skiing", less computer hacking..
