USB Midi Controllers Not Working On Windows 8.1 (SOLVED!) [Windows Update]

Anonymous

Hello, I have a problem (see subject above).

I have been trying to fix it on my own but nothing seems to work.

I have never had this issue before and I have been Producing music since XP.

On Windows 8 my midi controllers worked just fine. As soon as I updated via windows store, My controllers have become unresponsive.

I have checked (And updated!) under device manager all of the Universal Serial Bus Drivers.

Everything seems to be working fine there, except when running any DAW (digital audio workstation) such as: FL Studio, Cubase, Pro Tools, Ableton, Ripper, Studio One, Reason.

The midi controllers show up as available but do not send or receive any midi messages.

Both my external Audio Interfaces work as far as Outputting sound in both Directwave and ASIO.

But midi does not.

PLEASE HELP, I do not EVER wanna be a MAC fanboy... but this Windows 8.1 update is pushing me away.

No Midi Controllers = No New music from me = Shopping around for a new system pretty soon :(

Any help on this would be greatly appreciated.

Fix for this issue is in August update released this morning.  Please install update.  With this fix, you don't have to apply the registry setting to workaround the problem.

We were able to repro the issue with TEXTECH INTERNATIONAL LTD. (USB\VID_15CA&PID_0101 ) MIDI device. This device works when connected to 2.0 but not on 3.0 port. We debugged the issue and found the regression.

The 3.0 host controller driver in Windows 8.1 is forwarding a MSOS descriptor query to the device and that some how causes the device to get confused. The interesting part is that the even though the device is not fully functional, it doesn't fail any I/O. So from looking at the bus trace, every thing looks good. It is this one query that is sent during initialization causes the device to sulk, and then it never internally recovers.

Windows 8 doesn't send this query.

Another thing to note is that this issue manifest only for composite devices.

Fortunately there is a registry override to inform the core USB stack to not send this query. So I request you to apply the registry setting for now to workaround the issue.  We will try to get this fix added to a future update and roll it out widely. 

Get the VID/PID/REV ID of the device from the device manager. For example, for the device I'm using the VID/PID/REV values are 15CA/0101/F110.  With that, create the following registry entry (this registry key might have been already created in some case) and set the "osvc" value to 00 00.

HKLM\System\CurrentControlSet\Control\usbflags\15CA0101F110\

    REG_BINARY “osvc” = 00 00

Unplug and replug the device.

Let me know the results.

    Hi, Did you manage to sort this problem out.

    It seems as if Microsoft have given up on Music Production PC,s

    and just left it up to Applemac.

    I have been trying to recover my Pro Tools recording studio for nearly a year now after a win 8.1 upgrade.

    The software is wrong, the drivers are wrong, the interface is out of date  ....

    and now it won't even input basic midi keyboard

    and  my new  high spec software synth has locked up

    So I would be interested to know how you got on.

    i am having exactly the same issue. If i connect my Alesis DM7x i get no triggering at all from the pads. However if I connect my Akai MPK mini using the same USB cable it will trigger the VST
