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.

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,
I am confused - today it works :-)
I tried it on 3 different days with rebooting all devices that are involved. Today Windows obviously used it's self healing capabilities (without putting my hand on it) and all MIDI is running now....
Thanks for your help!

Hi DevonZC
Are you sure you have the same keyboard version as me?
You have to look under "Hardware ID" instead of under "Device Instance Path" to get the "REV", the last 2 bytes in the USB flag. If so, then all I did was to restart the computer and the USB keyboard.
Hi, I have a similiar problem to that mentioned in the posts before:
My USB-MIDI-device doesn't work neither on a USB 3.0 or USB 2.0 port.
I have tried the workaround by changing the USB flag in the hope it will solve the problem but it doesn't work.
I use an ePiano with my Surface Pro 2 (win 8.1, 64 Bit). If I connect the piano to my PC it will be recognized as "Medeli e-Drum" and a Microsoft Driver is installed without problems.
Here are Screenshots of the driver specifications and the device Manager:
The MIDI of the piano worked under XP and Win7 on an other PC. I don't know if it would work under Windows 8.0. But now there is a problem with win 8.1 as described by many users. I tried both, the USB3 and USB2 ports but MIDI doesn't work.
In the hope it could be the same problem that was solved with advice of Elias I edited the registry:
But now I have no more idea how to get MIDI work on my 8.1 machine.
Are there any further possible solutions?
Thanks for all your help!
Devon
