I got one of these a while ago and I've been working on and off at putting together a driver. Note that the driver has seen very little testing (I just added write support a few hours ago), it still has a few big kludges and it only works with one of the two revisions of the Prolific PL2307 that exist. Don't use it on a disk containing anything important! Note that with the "uhci" host controller, this device like many others will be dog-slow to transfer anything. Things will improve a lot when the "bandwidth reclamation" patch makes it to -stable. A poorly-tested -stable version of that patch is at http://www.maths.tcd.ie/~iedowse/FreeBSD/uhci_bandwidth_reclamation.diff.gz With this I get about 600kbytes/s instead of about 50-100kbytes/s.
