>Description:
The Neuros Digital Audio Computer (USB) (http://www.neurosaudio.com/) needs DA_Q_NO_SYNC_CACHE quirk to function properly. The dmesg output of the failed attach attempt is as follows:

>How-To-Repeat:
Boot your FreeBSD 5.x machine (don't know about 4.x) and plug your Neuros Digital Audio Computer in.

The dmesg output of the successful attach:

umass0: vendor 0x0451 product 0x5409, rev 1.01/0.01, addr 2
GEOM: create disk da0 dp=0xc2f17050
da0 at umass-sim0 bus 0 target 0 lun 0

da0: 1.000MB/s transfers
da0: 19077MB (39070048 512 byte sectors: 255H 63S/T 2431C)

And with the device successfully attached, usbdevs -v gives the following output:

Controller /dev/usb0:
addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel(0x0000), rev 1.00
 port 1 addr 2: full speed, self powered, config 1, product 0x5409(0x5409), vendor 0x0451(0x0451), rev 0.01
 port 2 powered

Note that in FreeBSD 5.x releases before 5.2.1-RELEASE, I had to use the DA_Q_NO_6_BYTE quirk too.
