Hoping for help getting a USB interface to SmartMedia working. I get
ENXIO when I try to mount the SmartMedia as a filesystem.
Here are the gory details.
I have a kernel built from fresh RELENG_4 sources:
FreeBSD melchett.pinemarten.org.pri 4.5-STABLE FreeBSD 4.5-STABLE #1: Sun Feb 3 16:35:37 CST 2002 hrp@melchett.pinemarten.org.pri:/usr/src/sys/compile/MELCHETT i386
I made a cvsup copy of the source tree yesterday, so it's quite
recent.
The first problem was to recognize the CameraMate as a umass device.
That took a patch to umass_match_proto (stolen from the freebsd-scsi
archive), so:

if (id == NULL || id->bInterfaceClass != UCLASS_MASS)
return(UMATCH_NONE);
================================================================
When I boot with the CameraMate attached, the right things appear to
happen:
uhci0: <Intel 82371AB/EB (PIIX4) USB controller> port 0x1080-0x109f irq 9 at device 7.2 on pci0
usb0: <Intel 82371AB/EB (PIIX4) USB controller> on uhci0
usb0: USB revision 1.0
uhub0: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 2 ports with 2 removable, self powered
umass0: Microtech International, Inc DPCM-USB, rev 1.00/1.00, addr 2
uhid0: WACOM ET-0405-UV1.1-1, rev 1.00/1.11, addr 3, iclass 3/1
That agrees with usbdevs -v:
Controller /dev/usb0:
addr 1: self powered, config 1, UHCI root hub(0x0000), Intel(0x0000), rev 0x0100
port 1 addr 2: power 100 mA, config 1, DPCM-USB(0x0006), Microtech International, Inc(0x07af), rev 0x0100
port 2 addr 3: low speed, power 40 mA, config 1, ET-0405-UV1.1-1(0x0010), WACOM(0x056a), rev 0x0111
and camcontrol devlist agrees:
<eUSB Compact Flash \0001> at scbus0 target 0 lun 0 (pass0,da0)
Trouble appears when I try "mount -t msdos /dev/da0 /mnt":
msdos: /dev/da0: Device not configured
the console bleats:
(da0:umass-sim0:0:0:0): READ CAPACITY. CDB: 25 0 0 0 0 0 0 0 0 0
(da0:umass-sim0:0:0:0): NOT READY asc:3a,0
(da0:umass-sim0:0:0:0): Medium not present
That is not true; I have an 8MB SmartMedia card plugged in.
================================================================
Here's what I think is going on. When I plug the CameraMate into a
box running W2K, it shows up as *two* drives: the first one for the
CompactFlash slot on the CameraMate, the second for the SmartMedia
slot. When I read the drive properties with W2K, it tells me that the
CompactFlash is (ScsiPort 2 Target 0 Lun 0), and that the SmartMedia
is (ScsiPort 2 Target 0 Lun 1).
Can it be that the umass driver is only reporting the first LUN, so
the SmartMedia slot is invisible? If so, what do I do to fix it? Do
I need to hack umass_bbb_get_max_lun?
