Conflicts with MIDI driver

Hi,

I just purchased a Logitech Quickcam for Notebooks Deluxe. I downloaded the latest drivers from the website, and the camera seems to work fine. However, my USB/MIDI cable no longer works! This is a generic cable (Viewcon chip) that provides 2 MIDI connectors from the USB port. It makes use of a standard Microsoft driver. My system would recognize that the MIDI device was there, but not make the MIDI ports available.

I uninstalled the Logitech drivers, and now the MIDI cable works. But, I really need the camera to work too. Any idea what could be causing the conflict, and how it might be solved?

My system:

Compaq Presario V2210 laptop, AMD Turion, Windows XP Pro, 1.2GB RAM

Thanks!

Fred

Re: Conflicts with MIDI driver

Welcome to the Logitech Community Webcam Forum fpatton! :smileyhappy:
 
There was an issue a while back having to do with a MIDI keyboard that would stop working.
 
The solution was to update to the manufacturers MIDI drivers for this device, even though "class" drivers were already on the system.
 
Is the camera on a separate USB Controller, or doesn't it matter where you plug things in?
 
Version of QuickCam that is installed?

Re: Conflicts with MIDI driver

The drivers were 10.0.0, build 1439, downloaded Thursday or so. My laptop has three USB 2.0 ports, and I had the camera plugged into one of them. The MIDI cable didn't work in any of the ports. The only combination I didn't try was the camera and the MIDI cable plugged in at the same time. Thanks for your help!

Re: Conflicts with MIDI driver

I should also add that there are no "manufacturer's drivers" for this device. They claim that the drivers are built into the device, but I suspect that just means that they know all Windows XP machines have the correct driver. So there's nothing to download, although I did look. I also tried installing drivers from a cable that I suspected used the same chipset, but no luck.

Re: Conflicts with MIDI driver

I encountered a similar issue, well not similar in your specific case, but the fix might be the same.
 
Basically, I had this Audio USB port analyser tool that stopped working when I installed QuickCam 9.5. While trying to see what was going on, I noticed that Logitech installs an extra filter driver to the media stack. The registry key for the media stack is here:
 
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96C-E325-11CE-BFC1-08002BE10318}
 
The "LowerFilters" entry had a reference to both the tool... and this new component called "LVUSBSta", which I eventually found where part of the camera drivers. I removed it until I was done using my tool (it fixed the problem). Then I added "LVUSBSta" back. I don't know the implications of removing it (I didn't use my little cam at the time, I was working!), I wonder if the Audio Echo Cancellation might be effected?
 
Eitherway, you have to be extra careful if you want to play with these registry keys. The class filters are used for all MEDIA devices, so any flubs, and you wipe out all the devices you see under Device Manager's "Sound, Video & Game Controllers"! Backing up your system is highly recommended (set a restore point, and have your XP CD handy)

Re: Conflicts with MIDI driver

There's a simple reason: the audio component of Logitech's webcam drivers manages to nuke any class-compliant MIDI (and audio, as well, I think) drivers. It's funny -- on the Mac, people are routinely accustomed to installing lots of plug-and-play, driverless MIDI and audio devices. So looking for the "manufacturer's driver" in this case is not really the point. I think the combination of Windows' handling of class-compliant drivers with ill-behaved driver developers (yes, Logitech, this means you) has caused many of the independent hardware vendors to develop their own drivers just to keep another driver from squashing them.

Anyway, if anyone knows how to work around this, I'm all ears.

Here's an example:

1. I connect a Novation ReMOTE SL MIDI keyboard to my machine. This installs the device as a USB Audio Device. To correctly label it as the SL, I can run Novation's own driver, which installs an .inf file that relabels the ports.

2. I install Logitech's current build of the QuickCam for Notebooks Pro. Webcam works fine. Novation keyboard no longer functions or appears as a port. Reinstalling the Novation driver doesn't work, so I ...

3. Uninstall the Logitech, reinstall the ReMOTE device, and ...

4. The circle of life continues.

What I can't sort out is why the QuickCam installs as the same USB Audio Driver in the first place. Any way you can hack the Registry to separate the two devices?

Re: Conflicts with MIDI driver

Workaround?
 
Did you try disabling the camera microphone, AEC, etc...?
 
Did you try re-installing the camera microphone using the "standard" Windows driver?
 
Thanks.

Re: Conflicts with MIDI driver

I think I did reinstall using the standard driver; I elected not to install the QuickCam software if that's what you mean. Since I did that on my most recent install, I can't even turn AEC off. (AEC shouldn't be the problem, though.)

What's the procedure for using the "standard" Windows driver for the mic? (This may not help, since the whole problem is that Logitech hijacks the class-compliant audio driver slot in the first place.)
