standard kernel and alsa drivers.

Fedora core 1 + planetccrma on a compaq presario x1000 (centrino) 
2.4.24-1.ll.rhfc1.ccrma
alsa-kernel-2.4.24-1.ll.rhfc1.ccrma 
motu fastlane usb 


1) Attempting to use usb-midi and usb-uhci (loaded by hotplug)

% lsusb -v | grep HCI
  iProduct                2 USB UHCI Root Hub
  iProduct                2 USB UHCI Root Hub
  iProduct                2 USB UHCI Root Hub


%  dmesg

usb.c: registered new driver midi
usbmidi: found [ MOTU Fastlane USB ] (0x07fd:0x0001), attached:
usbmidi: /dev/midi00: in (ep:82 cid: 0 bufsiz: 4) out (ep:02 cid: 0 bufsiz: 4)
usbmidi: /dev/midi01: in (ep:82 cid: 1 bufsiz: 4) out (ep:02 cid: 1 bufsiz: 4)

%  cat /dev/midi00

 [no output on midi input.  fastlane midi data 
  indicator flashed red on midi input]

%  dmesg

usb-uhci.c: uhci_submit_urb: pipesize for pipe c0010280 is zero
usbmidi: Cannot submit urb for MIDI-IN

  Tried adding to /etc/modules.conf:

options usb-midi ualt=1

  but didn't change behaviour when ualt set to 0 or 1


2) attempt to use uhci

% modprobe -ra usb-midi usb-uhci
% modprobe -a uhci usb-midi
% dmesg

uhci.c: USB Universal Host Controller Interface driver v1.1

usbmidi: /dev/midi01: in (ep:82 cid: 1 bufsiz: 4) out (ep:02 cid: 1 bufsiz: 4)

% cat /dev/midi00
% cat /dev/midi01

 [no output on midi input.  fastlane midi data 
  indicator flashed red on midi input]


% dmesg

usbdevfs: USBDEVFS_CONTROL failed dev 2 rqt 128 rq 6 len 101 ret -6
usb.c: registered new driver snd-usb-audio
usbmidi: Cannot submit urb for MIDI-IN
usbmidi: Cannot submit urb for MIDI-IN





3) attempt to use ALSA and usb-uhci

% modprobe -ra usb-midi
% modprobe -a snd-usb-audio snd-pcm snd-timer snd-rawmidi snd-seq-device

% dmesg

usb.c: registered new driver snd-usb-audio

% amidi --dump 
% amidi --dump --port="hw:0,0,0"
% amidi --dump --port="hw:0,0,1"

  [produced nothing on MIDI input.  the usb module red 
   light was flashing on MIDI input]

% dmesg

  [no new lines]


4) same results for ALSA with uhci
