Hi,
I decided to see if current infrastructure already supports
this gadget:
T: Bus=01 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#= 2 Spd=12 MxCh= 0
D: Ver= 1.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
P: Vendor=03f0 ProdID=0107 Rev= 2.00
S: Manufacturer=Shuttle Technology Inc.
S: Product=HP USB CD-Writer Plus
C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr= 0mA
I: If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=00 Prot=00 Driver=usb-storage
E: Ad=01(O) Atr=02(Bulk) MxPS= 64 Ivl= 0ms
E: Ad=82(I) Atr=02(Bulk) MxPS= 64 Ivl= 0ms
E: Ad=83(I) Atr=03(Int.) MxPS= 2 Ivl= 32ms
At Linux kernel 2.3.99-pre4 (plus some patches) I got as far as
getting the device recognized, and even probed to some extent.
All I did was to add following lines to "unusual" device list:
{ 0x03f0, 0x0107, 0x0200,
"HP USB CD-Writer Plus", US_SC_8020, US_PR_CB, US_FL_SINGLE_LUN },
Reading the kernel log (below) seems to indicate that proper SUBCLASS is
likely US_SC_SCSI, and not this "8020" ATAPI thing which was my first
pick...
Which ever usb-storage setup is used, for some reason I get now system
load-average raised by one unit -- raising it to 1.0+ ...
(Oh, and I don't like the end comment about unrealiable integrity..)
My machine is Alpha, if that has anything to do with the problem (e.g.
endianity issues..)

When running "modprobe usb-storage" I get now:
