It's still an issue on today's 7-stable.
I currently don't have time to upgrade to 8 so I don't know about that.

I've attached an updated patch for 7-stable, because the old one
doesn't apply anymore.

And here's dmesg output (btw, vendor id isn't recognised either):

umass0: <vendor 0x1005 USB FLASH DRIVE, class 0/0, rev 2.00/0.50, addr 2> on uhub3

da0: 40.000MB/s transfers
da0: 124MB (253952 512 byte sectors: 64H 32S/T 124C)

Without the patch I then get these messages repeatedly:

umass0: Phase Error, residue = 0
