	PNY's Attache USB 2.0 Flash Drive is a solid-state memory storage
device.  However neither the device nor the vendor are listed in
dev/usb/usbdevs and the drive fails to operate correctly.  The kernel
reports "Phase Errors" with varying sizes of residue (1024, 512, 0) as well
as numerous "Synchronize cache failed" errors.  fdisk(8) does not report
correctly and attempts to write the partition map or mount the drive fail.

The following patches were applied to a CVSup'd 5-CURRENT as of today (adds
the PNY vendor and the product ID which match my flash drive).  I guessed
at the command protocol and "ignore residue" quirk; the patches allowed
fdisk, mount, and read/write to work correctly.  The kernel still reports:

umass0: Phase Error, residue = 0
(da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi status == 0x0

repeatedly, but otherwise it seems to work correctly.  Someone with USB/CAM
knowledge might suggest a better fix; at least this is a [working] start.

	CVS to 5.1-CURRENT as of Oct 14 2003, use GENERIC or a kernel
configured with umass & friends.  Plug in USB 2.0 PNY Attache Flash Drive
and try to fdisk(8) or mount da0s1.  Kernel will report numerous Phase
Errors with residue and the operation will not succeed.  With the following
patches, fdisk reported the correct partition table and mount succeeded.
