I'm more inclined now to replace the MidiSport with another UA25. :)
Thanks for the help, Clemens, I might upgrade ALSA. If I do I'll send a
report.
Best,
dp
wMaxPacketSize 0x0020 1x 32 bytes
are the same for the MidiSport and the UA25. However, there's a lot of
information from that report. Is there any other particularly relevant
data I should gather from lsusb ?
No, anything else wouldn't be visible in the descriptors.
It's possible that the MidiSport's firmware uses some stupid algorithm
that doesn't put multiple MIDI messages into one USB packet. In that
case, using the latest snd-usb-audio driver from ALSA 1.0.21 or the
upcoming 2.6.32 kernel might help.
