>Description:
	Trying to use the Y-E Data USB floppy on my Sony VAIO PCG-Z505HE.

In short, "it doesn't seem to work". Reads and writes return quickly,
reads return all zeroes.

I'm not certain if this device is supposed to work -- it looks like
there's a quirk entry in umass.c for it, so I guess that means
it should function.

Of course it works under Windows ;-)

>How-To-Repeat:
	
 It probes OK:

umass0 at uhub0 port 2 configuration 1 interface 0
umass0: Y-E DATA FlashBuster-U, rev 1.00/1.28, addr 2
umass0: using UFI over CBI-I
scsibus0 at umass0: 2 targets, 1 luns per target
scsibus0: waiting 2 seconds for devices to settle...
sd0 at scsibus0 target 1 lun 0: <Y-E DATA, USB-FDU, 1.28> SCSI0 0/direct removable
sd0: drive offline


or with a floppy in:

umass0 at uhub0 port 2 configuration 1 interface 0
umass0: Y-E DATA FlashBuster-U, rev 1.00/1.28, addr 2
umass0: using UFI over CBI-I
scsibus0 at umass0: 2 targets, 1 luns per target
scsibus0: waiting 2 seconds for devices to settle...
sd0 at scsibus0 target 1 lun 0: <Y-E DATA, USB-FDU, 1.28> SCSI0 0/direct removable
sd0: mode sense (4) returned nonsense; using fictitious geometry
sd0: 1440 KB, 1 cyl, 64 head, 32 sec, 512 bytes/sect x 2880 sectors


Every time I try to do an operation, though, I get the kernel printfs
about the label and geometry:

sd0: could not mode sense (4/5); using fictitious geometry
sd0: no disk label
sd0: could not mode sense (4/5); using fictitious geometry
sd0: no disk label
sd0: could not mode sense (4/5); using fictitious geometry
sd0: no disk label
sd0: could not mode sense (4/5); using fictitious geometry
sd0: no disk label
sd0: could not mode sense (4/5); using fictitious geometry
sd0: no disk label
sd0: could not mode sense (4/5); using fictitious geometry
sd0: no disk label

Attempts to write a label were unsucessful, either in-core
or on-disk.
