USB card reader

This belongs on netbsd-help, not tech-kern.

I use a sandisk imagemate 12-in-1 and a nonmae reader and
they attach:

umass0 at uhub4 port 5 configuration 1 interface 0
umass0: SanDisk ImageMate 12 in 1 Reader/Writer, rev
2.00/93.17, addr 2
umass0: using SCSI over Bulk-Only
scsibus1 at umass0: 2 targets, 4 luns per target
umass1 at uhub4 port 6 configuration 1 interface 0
umass1: Generic USB2.0 Card Reader, rev 2.00/1.9c, addr 3
umass1: using SCSI over Bulk-Only
scsibus2 at umass1: 2 targets, 4 luns per target

sd0 at scsibus1 target 0 lun 0: <Generic, STORAGE DEVICE,
9317> disk removable
sd0: drive offline
sd1 at scsibus1 target 0 lun 1: <Generic, STORAGE DEVICE,
9317> disk removable

This is on current/i386 with Intel EHCI.

The ehci driver probably is not quite right.  I use current
and I
don't know if there are any specific fixes.  EHCI is a spec
from
intel, and they also make chips.  Others make chips, and
it's been my
impression that other chips may not have exactly the same
interface.

I have found that accessing cards that aren't there can
lead to hangs.
My cards map as follows
sd0 CF
sd1 (probaly MS)
sd2 SD
sd3 xD (probably SM)
