freebsd stable - Jan 2009 - USB devices fail to attach as umass scsi da[n]

This dictation recorder fails to attach via usb.
The same problem occurs with a Nikon Coolpix L1.
Both work fine under windows on the same hardware.

Do I need to do something to GENERIC to get this working?
The machine is spare so I can recompile and submit debug
info as need be. Thanks.

GENERIC, RELENG_7 a few days past the 7.1 release.
SuperMicro 370DER motherboard, most recent bios.
The Nikon is set to mass storage. The RCA has no such option.
Both have the latest firmware.

By the way, the RCA records natively in mp3 format. Handy as most
seem to use some closed format. Worth a try if you need one.

You can try to add a quirk for this device :
http://www.root.org/~nate/freebsd/scsi/quirks.html

[not sure if this is uptodate, i did it in the past (RELENG_5/6) for
my mp3 player]

I would start with a DA_Q_NO_SYNC_CACHE quirk.
