Sorry for the delay in getting back to you; work very rudely intruded on my
life last week..;) Regarding your request, the relevant line from
stream0 looks like:
URBs = 5 [ 2 2 2 2 2 ]
Without the nrpacks=2 option, the URB line looks like:
URBs = 5 [ 4 4 4 4 4 ]
I should point out that things have apparently changed some in the last
week. Using the code I checked out of CVS just a few hours ago, I no
longer get continuous messages in the syslog. Instead I seem to get a few
lines of those usb-check-bandwidth messages each time a new song is loaded
by xmms. Then, while the song is playing, I will get occasional breaks in
the sound accompanied by a few messages in the syslog similar to the
following:
Jun 12 23:36:58 snoopy kernel: usb.c: usb-check-bandwidth would have
FAILED: was 912, would be 1140, bustime = 228 us
Jun 12 23:36:59 snoopy last message repeated 715 times
Jun 12 23:36:59 snoopy kernel: usb-uhci.c: iso_find_start: gap in seamless
isochronous scheduling

Jun 12 23:37:19 snoopy last message repeated 10003 times
Jun 12 23:37:19 snoopy kernel: usb-uhci.c: iso_find_start: gap in seamless

Jun 12 23:37:19 snoopy kernel: usb.c: usb-check-bandwidth would have
FAILED: was 912, would be 1140, bustime = 228 us
Also, a dialog box will sometimes pop up saying "snd_pcm_wait: Input/output
error"
