I have a Studiologic Numa which connects via USB. For some reason when I connect the USB cable it powers on the keyboard but mac does not recognize it at all, and Audio Midi Setup is useless when I ask it to rescan midi. This is a brand new macbook pro running Snow Leopard. Oddly enough, it works fine with my old macbook running Leopard.
Usb Keyboard Not Recognized
There seems to be a tremendous bug in Windows 10 whereby class compliant USB Midi devices are not recognized properly (read as composite devices instead of USB Audio devices, and with an error flag in Device Manager) or are recognized but cannot communicate to DAW programs that are supposed to use them.
I have searched for hours, and found nothing but many, many threads of frustrated users. Help options seem to be limited to useless generic posts about contacting the device manufacturer (even though this issue occurs on TONS of devices and again, these are class compliant devices) or trying Windows troubleshooting or repair (but this is an inherent bug, so there's nothing to fix).
Is there any hero out there who has solved this problem? Or anyone with some kind of access to a higher level of tech support? I don't imagine the fix would really be that difficult for dedicated high-level MS engineers, but it's clear that no one has solved this yet and it's a major Windows 10 shortcoming.
I've just spent $800 on a new Windows 10 PC, and am very frustrated to find I can't use my keyboard anymore without spending another $50 on a MIDI USB device cable that has specific Windows 10 drivers.
Thanks!
If your USB MIDI device is not being recognized by your computer, consider the following:
Windows
Check the Windows Device Manager to see if your device (or any new devices) appear. MIDI devices should appear in the Sound, video and game controllers category. If they appear with a yellow question mark or exclamation point, right-click and choose to update the driver.
Mac

For devices that require a driver, disconnect the device, uninstall the drivers, repair disk permissions, then re-install the latest drivers. Repair disk permission is done using the Disk Utility which can be found in the Applications>Utilities folder. Open that up and select your System Drive (usually labeled Macintosh HD), click the First Aid tab and click Repair Disk Permissions.
General
- Try connecting to different USB ports, then check the Device Manager again
- If your device is connected to a USB hub, try connecting it directly to ports on the computer. Alternatively, if the device isn’t being recognized on the built-in ports, try connecting to a USB hub
- Test the device on a different computer
- Test with a different USB cable
Note: If you are using a long USB cable, try a shorter cable.
