Hi All, I couldn't use my usb device because the default buffer size (16*1024 bytes) was too much to be allocated (dma changes that happened a while ago). The following is a patch to make it a tunable: http://www.cnd.mcgill.ca/~mat/uaudio-HEAD-buffersize-tunable.diff.gz This is not for RELENG_5. If you want it there, you'll have to catch-up with the work the Julian did in December first: http://www.cnd.mcgill.ca/~mat/usb-RELENG5-to-HEAD-Mar05-2005.diff.gz For both patches you'll have to: cd /usr/src patch < /path/to/unzipped.diff And then rebuild your snd_uaudio modules cd cd /usr/src/sys/modules/sound/driver/uaudio/ make make install Would love to hear if this works for anybody else, --Mat
