XP Dual Core USB MIDI driver problem

Posted: 08-28-2006, 05:48 PM
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.

like here:
http://groups.google.com/group/micro...c43f5b82a5d0c8

But I have not been able to find a solution.

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?

thanks
Mike

I have this exact same problem!!!!! So glad I found this post, hop
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
MIDI keyboard with my laptop but I can't seem to get it to function wit
my music composition software (Sybellius).

Here's what I did: I inserted my USB cable into my keyboard which has
USB port on it and then inserted it into my laptop. I then powered o
the
keyboard and Windows did it's typical "new device detected" deal. I
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 tha
the
software program I use tells me that it does not detect any MID
devices.
I've looked over the softwares manuals, tutorial vidoes, everything, i
is
NOT the software program.

Here's what I'm thinking:
a.) My sound card doesn't support MIDI input (I called Toshiba abou
this
and they just did the typical, "lets see if your sound card i
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 m
workplace offers this to me for free, yay for me!)
c.) The wrong driver is installed. If this is the case, I have no ide
how
to change this and would appreciate some explanation on how to instal
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 tha
was the conflict.

Someone please help us and reply to this post!

Many thanks; would never have figure it out either. my usb midi no
functioning also.

I was apprehensive about modifying the registry directly. I know enoug
to find and modify registry. I don't know enough details about th
registry to be sure I was doing the right thing. Indeed I accidentl
disabled my typing keyboard (as opposed to MIDI keyboard) by mistake b
deleting the first LowerFilter I came to using the search facility.

Advice:

There may be many registry entries with the HEX name wotsit:
4D36E96C-E325-11CE-BFC1-08002BE1031.

You need the one that refers to game controllers and sound. Do no
delete lowerfilters anywhere else.

You only need to delete one lower filter. Leave the uppers alone;
didn't have to delete any of them to make it work.

To be safe:

i) Create a system restore checkpoint unde
start->programs->accessories->system Tools-> system restore

ii) If you screw up and delete the wrong lower filter so that you
keyboard stops functioning or worse you can then do a system restor
after wards (providing you don't delete the mouse lower filter). If yo
delete the mouse lower filter AND the keyboard lower filter the
apparently you have to do a CMOS reset. Don't take my word for that...
use the net on someone elses computer to find the solution...

You've been warned!

Have fun

Dizzy..
