Post subject: XP Dual Core USB MIDI driver problem Archived from groups: microsoft>public>windowsxp>device_driver>dev (more info?)
Hi,
I manufacture a USB MIDI class device that works on many different PCs
running XP and MACs running OSX, but it does not work on 3 customer
machines that are all Intel Duo dual cores running XP. I have found
only one post on the web with the same issue with USB MIDI class
devices other than ours.
The device is found by the OS and is installed normally. It appears as
a USB composite device and as a USB Audio device, just like it does on
all other XP systems. The problem is that it is not installed as a
MIDI device in XP.
One customer was able to get our USB MIDI device to work after a clean
re-install of XP, but it stopped working after they installed the extra
drivers/ updates from the OEM disk.
systems with the problem so far:
1. Desktop Intel PD 805 Dual Core (2.66 Ghz ), motherboard is Abit NI8
SLI
2. Unknown Acer dual core laptop
3. Acer Aspire 5672 WLMi laptop
Can anyone suggest how I can get in touch with MS directly to solve
this?

I'm also having this problem and have been searching for a solution for
a while. Have you had any luck?
My laptop is an Acer Aspire 5670 Core Duo and my controller is an
Alesis Photon X25.

I have this exact same problem!!!!! So glad I found this post, hope
someone can really find an answer.
I have a Toshiba Laptop with Windows Media edition installed on it.
It's
the Satellite A105-S4134. I am a music teacher and I am trying to use a
MIDI keyboard with my laptop but I can't seem to get it to function with
my music composition software (Sybellius).
Here's what I did: I inserted my USB cable into my keyboard which has a
USB port on it and then inserted it into my laptop. I then powered on
the
keyboard and Windows did it's typical "new device detected" deal. It
then
automatically installs the driver and calls it a "USB Audio Device."
I'm not
sure if that's right because it is a MIDI device... Anyway, after that
the
software program I use tells me that it does not detect any MIDI
devices.
I've looked over the softwares manuals, tutorial vidoes, everything, it
is
NOT the software program.
Here's what I'm thinking:
a.) My sound card doesn't support MIDI input (I called Toshiba about
this
and they just did the typical, "lets see if your sound card is
working..."
>< I don't know how to tell if it does or not.
b.) Windows MCE is no good for this and I need XP (easy fix because my
workplace offers this to me for free, yay for me!)
c.) The wrong driver is installed. If this is the case, I have no idea
how
to change this and would appreciate some explanation on how to install
and
find the appropriate MIDI driver. I already did the "update driver"
option and windows said this is the latest Driver.
d.) I guess it could be the processor but I really wasn't think that
was the conflict.

Hello all,
I'm developing a USB MIDI class device too. It is still not in production
as I got exactly the same issue.
My device is working fine on VISTA and many XP PCs but is failing on others.
It was not easy to diagnose as I was developing on a dual core and was
searching in the "XP direction" instead of thinking about this dual-core
issue.
More and more of my customers will buy a dual core and will fall into this
issue.
I checked many ways of overcoming this, spend much valuable time looking at
my USB
descriptors - My first reaction is always to think that I'm wrong - and came
to the
conclusion that it was a Microsoft issue.
I'm contacting Microsoft now to get a fix.
I will report if succesfull.
Your post was most helpfull as it pointed me in the good direction.
Thanxs for it,
Thierry

I had the exact same problem with the same Toshiba computer ! I updated
the Realtek 97 AC '97 soundcard from the Realtek website and after that
Windows recognised the Midi devices. Hope this helps.
