I asked this question on the ALSA user's list with no response (yet!)
Thought maybe someone on this group may have come across this.
Can't get midisport8x8 to work. I think that the firmware is not loading.
Some notes:
---
I have usbfs running (the dir is there), installed the hotplug and
fxload packages from linux-hotplug and "make install" the
midisport_firmware-0.5.
---
modprobe:

=====================================
Midisport does not show up anywhere. So, I fear that fxload and/or
hotplug scripts are not working.
How can I check this? And, how can I enable these to work (if this is
the problem)?
thanks much!

Hi,
I had a similar problem with the MidiSport 2x2
I discovered that doing a reboot somehow gets the thing working (the
usb-LED on the device starts burning during the boot, and the device
runs fine afterwards).
I do not know why though.
sincerely,
Marije

New subject: [linux-audio-user] Midisport 8x8 - firmware not loading; is my guess
Hi Brad,
I use a 2x2 here. I have a couple of differences from you so I've
edited you file below to look like mine.
The firmware loader I'm using comes from here:
http://usb-midi-fw.sourceforge.net/
It says the 8x8 is supported, but that said, I seem to remember
problems reported for the 8x8 version of this device.
HTH,
Mark

It looks like you added "index". I did read somewhere that index helps.
Is this still needed in these days?
I'll try it.
I have read that the "alias /dev/.." lines are no longer needed and
actually may be a problem if included. Sure would like to get
confirmation on this since it seems others _do_ add them. Anyone?
I don't think it's a ALSA problem as much as the hotplug scripts aren't
running automatically.
Yeah, that's where I got the scripts too (just followed the ALSA
directions):

I would not presume to guess what Alsa wants. IT's rule set if far
beyond my meager abilities. The file I gave you was suggested by
Clemens. Who am I to argue?!
The other thought that came to mind is that the firmware file you
extracted from your MidiSport disk might not be right. Have you double
checked that step? In my case I ran wine to extrat the files, but wine
aborted before it finished. However the firmware files were in a temp
directory somewhere and I was able to use them. How did you get yours?

It may be possible that the UHCI driver doesn't receive interrupts.
Try enabling or disabling ACPI.

I just booted with acpi=off and checked the logs to make sure it was
off. No difference.
I just plugged in a usb cardreader, tail'd the log and the device was
recognized. (disconnection was detected as well).
From this short experiment, it seems to me that the usb hotplug
detection is working.
Any other ideas?

Just to follow up what I said i'd do: I did reboot with acpi=on and the
cardreader was detected when plugged in and when unplugged.
Unfortunately, the Midisport 8x8 is still not recognized.
Just to let you know before you ask ;-) yes, the Midisport 8x8 _does_
work under Win2k.
So, at this point, wouldn't it be fair to say that the loading of the
firmware is not necessarily the problem.. but the recognition that the
8x8 was plugged in is the first issue? (couldn't Linux recognize that
the 8x8 was plugged in, just as an unrecognized device.)

Hi,
FWIW:
I have a similar problem with the 2x2:
when I connect the device, it shortly shows up in lsusb, then the leds
on the device all blink once, and then it does not show up anymore in
lsusb.
Other usb devices work fine.
The MidiSport 2x2 works fine after a reboot, while the MidiSport 2x2
is still plugged in; it then immediately gives the nice burning
USB-led sign that it is allright, even before I start booting Linux.
sincerely,
Marije

The MidiSport 2x2 works fine after a reboot, while the MidiSport 2x2
is still plugged in; it then immediately gives the nice burning
USB-led sign that it is allright, even before I start booting Linux.
Thanks for the input. I tried different configurations (rebooting with
it plugged in, out... etc.) Unfortunately, my 8x8 does not behave like
your 2x2. At this point, I'm stumped. I'm wondering if it's a hardware
issues -- perhaps the voltage is just under a certain threshold.

New subject: [linux-audio-user] Midisport 8x8 - firmware not loading; is my guess
I will try it tonight with my new machine, but I had the 8x8 working
on an older machine using CCRMA for rh9. Its been a while since I have
booted that machine, but I know it was working (if that was a worry
for you)
I do remeber that it had to be plugged in and turned on before the
machine booted

Hi,
FWIW:
I have a similar problem with the 2x2:
when I connect the device, it shortly shows up in lsusb, then the leds
on the device all blink once, and then it does not show up anymore in
lsusb.
Other usb devices work fine.

New subject: [linux-audio-user] Midisport 8x8 - firmware not loading SOLVED
Thanks for everyone's help.
It was, indeed, an electrical issue. I took a powered USB hub and put it
between the PC and the 8x8 and Midiman instantly showed up on lsusb
Again, thanks for all your help!
