Still no joy. I'd been meaning to do the standard DA_Q_NO_6_BYTE hack
last time I left off with this. Although umass attaches to the device,
the rest of the attach process doesn't go as expected (even when I do
sysctl kern.cam.da.no_6_byte=1).
For example:-
umass1: M-Systems DiskOnKey, rev 1.10/2.00, addr 8
umass1: Get Max Lun not supported (SHORT_XFER)
triage:~ % s camcontrol devlist
<Sony MSC-U01N 1.00> at scbus0 target 0 lun 0 (da0,pass0)
<M-Sys DiskOnKey 2.51> at scbus0 target 1 lun 0 (da1,pass1)
triage:~ % s camcontrol inquiry 0:1:0
Exit 1
(Times out).
Occasionally I'll see BBB resets being initiated by the umass driver. I've
tried this with the DiskOnKey plugged into both a downstream hub and directly
into the root hub itself.
Running udesc_dump against the DiskOnKey when it's plumbed in as a ugen device
gets interesting:-
[..]
Standard Interface Descriptor:
[..]
bInterfaceClass 08
bInterfaceSubClass 06
bInterfaceProtocol 50
[..]
So it's being picked up by the umass driver based on its primary interface
class and subclass, and 0x50 = 80 decimal, which is UPROTO_MASS_BBB_P, which
means umass thinks it's an Iomega Zip 100.
Since I got my MemoryStick and CompactFlash support sorted out, this isn't
a priority for me, but if anyone else wants to have a shot, I will help
where I can.
