XP Dual Core USB MIDI driver problem

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...3f5 b82a5d0c8

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

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.

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.

[ashwin_athani]

Did you have any reaction from anybody? I'm verry interested in the result! i've exactly the same problem :S

Are you now able to use the MIDI device now?? Did you have to change the soundcard as suggested by one the member for it to work??

We are also facing the same problem as you did. It would be very nice to see a update on this issue.

Give this a try...Found it on another forum and just posting it around as I had big problems too.....

The Problem is really caused by Logitech Webcam
i do not know if it works if i install it again, i wont !!!!
FADERBOX IS GREAT !!!!!

I found a fix that worked for me and I hope it works for anyone else experiencing the same issue. I had to Manually delete the UpperFilters and LowerFilters registry values. (maybe only one exists at your place)

To Manually delete the UpperFilters and LowerFilters registry values, follow these steps:

1. Start Registry Editor (Regedit.exe).
START > RUN > (Type) REGEDIT (and hit ENTER)

2. Locate the UpperFilters and LowerFilters value under the following key in the registry
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E96C-E325-11CE-BFC1-08002BE10318}

3. On the Edit menu, click Delete, and then click OK.

Now you have to UNINSTALL THE USB AUDIO DEVICE, UNPLUG IT, AND REPLUG IT AGAIN

VOILA !!!! WORKING !!!!
PS, somehow u have to Use the Emulated USB AUDIO DEVICE Drivers

Many many thanks...

I've been fighting with the same problem for months (since I bought my MIDI device). When I tested it it worked on my laptop, but failed on my desktop. Then I started checking the configuration on my desktop by removing devices and drivers. I've tried different solutions suggested in internet, included re-install XP. Then I could identify that my Logitech QuickCam is the trouble maker. I've played around with it. Whenever I removed the QuickCam driver my MIDI device is back. I also noticed Logitech inserted the file LVUSBSta under the USB Audio driver. But I just can't remove it.

With the below suggested solution, I deleted (only) LowerFilters and as you said VOILA! :-)

That's great, thanks again and agian...

Many thanks; would never have figure it out either. my usb midi now functioning also.

I was apprehensive about modifying the registry directly. I know enough to find and modify registry. I don't know enough details about the registry to be sure I was doing the right thing. Indeed I accidently disabled my typing keyboard (as opposed to MIDI keyboard) by mistake by 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 not delete lowerfilters anywhere else.

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

To be safe:

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

ii) If you screw up and delete the wrong lower filter so that your keyboard stops functioning or worse you can then do a system restore after wards (providing you don't delete the mouse lower filter). If you delete the mouse lower filter AND the keyboard lower filter then 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

Hi, I have more less the same problem, I have a Novation Remote25 Le and i use a computer with DualCore,2Gb Ram, 500Gb HD and using XP with services pack 2.

XP add witout problem my midi controller, but once I want to play or record ,for example in Reason 4 I can't listen nothing. Reason 4 add without problems my midi, but can't send signal or sometimes I can listen whatever I play but not the completes notes.

I was reading about delete LowerFilters in regedit, but I dont have cams in my computer.

Please I need the fix.

I had the same problem where my Logitech web-cam driver conflicts with the Midi Keyboard (Evolution MK-425C) and thanks to various posts have solved the issue. I am now able to use the Logitech web-cam at the same time as the midi keyboard.

Initially I only had the midi device installed and it worked fine. Then, I installed the Logitech driver and the midi device was no longer recognised by Reason (my music software).

To solve the problem, I did the following:

1. Go into the registry editor (go to Start Menu, Run and type regedit)

2. Go to this location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E96C-E325-11CE-BFC1-08002BE10318} and delete the two items "LowerFilters" and "UpperFilters"

3. Go to this location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{6BDD1FC6-810F-11DO-BEC7-08002BE2092F} and delete the item "LowerFilters"

4. Go to this location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{6BDD1FC5-810F-11DO-BEC7-08002BE2092F} and delete the item "UpperFilters"

5. Move back to the root of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\

6. Launch a search (i.e Ctrl F with the option to search in "Data") and type "LVUSBSTA". For any place found (only in the "Control\Class" area), just delete the "LowerFilters" item (it is the item that contain the value LVUSBSTA found). For me, I didn't find any other places than the ones mentioned here.

7. Then uninstall the midi device driver, unplug it and plug it back in. Windows should recognise it and install it and it should work!

Thanks to all the people who posted in various forums. All I've done is summarise the bits and pieces that eventually worked for me.

Can anyone help fix this problem on MAC OS 10.4

I have Vestax VCI-100 Midi Controller and i just got M-audio fast track pro audio interface, When i connect the Audio interface the USP Midi Controller doesn't appear..

Can Anyone help me Work with Both at the same time!

operating system : Mac OS 10.4

[Jpalm]

so i've had the same issues, with my duo core XP sp2, but i don't have a logitech webcam or any cam. I tried doing the register edit trick but the sound and video card didn't have any "upperfilters" "lowerfilters" in the places discussed earlier. so i deleted some that were maybes and restarted and unistalled, re installed and it STILL didn't work .

does anyone have any suggestions know? basically everything is installing fine. but windows won't recognize it in my control panel as a midi device.

I don't have an answer for you I'm afraid as i have the same problem. What
you may like to know though is that the MIDI cable will send data to your
device. So the problem IS software related. Microsoft don't seem to want to
release a driver for this fix unfortunately. So you're stuck.

The posts of TitoPulpo and impermanence33 worked for me. Thanks very much both of you guys!!

The steps of impermanence33 worked better, since now I have both my usb midi device and Logitech Cam working. Also the label "Sound, video and game controllers" remains attached.

Hei , ive just made this great song on Band -in a - box , and then I find out
that i dont have Midi input as described above due to the dual core problem .
I dont have an extern midi-device or MIDI cable , but would that help to
overcome the problem, and enable me to use the computer ?
Just to make sure if im truly f..ked....
Think it is disgusting that Microsoft wont addres this problem...
