I just noticed on the HP website the following:
"There are two revisions of external USB 8200e/8210e drives. To verify
which version you have, locate the product model number on the
bottom or back of your drive. If the drive model number ends with an
"A" then your drive is compatible with the built-in Windows 2000
driver. If your drive model number ends with a "B" then a driver update
is required. "
So it seems that there are indeed two models in the 8200e series. I
have a "C4453A", so I bet yours ends with "B". This identification might
also help future users to select the right USB driver for their model.
I have been playing around with cdrecord 1.8.1 (with linux patch, kernel
2.3.99-pre7) to see if I can write CD's. It says my CD writer is the
following (libscg version "schily-0.1", command used:
cdrecord -dev=/dev/sga -inq)
Devicy type: Removable CD-ROM
Version: 2
Response Format: 1
Vendor_info: 'HP '
Identifikation: 'CD-Writer+ 8200'
Revision: '1.0f'
Device seems to be: Generic mmc CD-RW
So far so good.
However, when I try to write a CD-RW disc, it reports the following:
Using generic SCSI-3/mmc CD-R driver (mmc_cdr).
Driver flags : SWABAUDIO
Starting to write CD/DVD at speed 2 in write mode for single session.
Last chance to quit, starting real write in 1 seconds.

Nothing was written (as far as I could check). I also tried the 'blank'
command with several different options, I'm getting about the same
error.
The usb-storage module does not seem to know the commands that are
issued?
usb-storage.c: Command <NULL> (10 bytes)

cdrecord -prcap -dev=/dev/sga gives the following:

which is all very correct.
Does anybody have a clue as to what is the problem here? Is the usb-scsi
bridge capable of handling CD write commands?
