Prolific PL2507 support for umass driver ?

Hi there, hope someone can help me out in a minor foray into
I've got a non-working Freecom 250GB Classic HD (USB!), it's
basically a plain IDE drive and a small board with the PL2507
USB<->IDE bridge on. (In a cheap black plastic box with the
mandatory blue led stuck on the front.)
However FreeBSD fails to attach it on all counts, I've got a
usb sniffer, the source (and I've managed to get as far as
having the thing probe and ID "correctly") but it always
fails to start an endpoint with error 6 / IOERROR and doesn't
attach properly. (That's after twiddling with the device options
and forcing ATAPI rather than say SCSI or BBB or whatever the
other choices are hardcoded into umass.)
Apparently these devices work fine in "Linux" [*], and it's fine
on Windows as well for which I have usbsniff installed, and can
hotplug between windows and a freebsd box quite easily, but I'm
still not getting my endpoints setup.
Before anyone mentions it, I'm just rebuilding after a cvsup of
RELENG_6 from last night - if that's not new enough and someone has
already or recently done this work then please let me know.
Thanks in advance for any help,
P.S. I'm fully aware that this piece of hardware may not conform
100% to the spec!
[*] google told me that some folks have them working somewhere.
