[i don't see -usb list, so CC'ed to -current hoping someone will be interested]
Recently i bought the A-DATA USB 2.0 SpeedDrive (256 MB flash drive).
I tried it on my system, which is now:
FreeBSD goshik.binep.ac.ru 4.8-STABLE FreeBSD 4.8-STABLE #29: Sun Aug 10 16:50:19 MSD 2003
goshik@goshik.binep.ac.ru:/usr/obj/usr/src/sys/GO i386
Device appeared in dmesg as hub+storage combo:

There is no class identifier here

I tried to add quirks to sys/cam/scsi_da.c with no success. As was
advised by Nate Lawson in recent threads on DA and USB quirks,
i was going to try some USB quirks, but then i noticed a couple
of strange things. First, marked above lack of class identifier
for mass storage part. Then, from the output of the usbd -v:

Here we have:
1) vendor ID 0x067b - according to sys/dev/usb/usbdevs this
is Prolific Technology... hmmm
Am i right that to make proper quirk, i need to put product IDs
into sys/dev/usb/usbdevs? If yes, how it can be done in this
situation? System always shows A-DATA Technology Inc. as vendor,
but it is unknown in the usbdevs.
2) product 0x2515 (not in usbdevs) class 0x0009 (hub) - well,
it is identified as hub (UICLASS_HUB in usb.h)
product 0x2517 (not in usbdevs) class 0x0000 - shouldn't
this be 0x0008 (UICLASS_MASS in usb.h)?
So: usbd reports vndr=0x067b but prints A-DATA - is this harmless?
usbd reports clss=0x0000 for mass-storage part - i think this is bad?
products identifiers are not in usbdevs - ?
What can i do to make the thing work?
TIA,
Igor
