    Default MAudioUSBMIDI.sys 5.10 causes BSOD - UC33e on Win7 x64 SP1

    My UC33e stopped working, no matter how I try to remove and reinstall the driver.
    The hardware works, it turns on, but no software can read its signals.

    And if that's not enough, I occasionally get a BSOD from MAudioUSBMIDI.sys.

    This is the minidump:

    042712-27112-01.dmp 27/04/2012 23:55:29 SYSTEM_THREAD_EXCEPTION_NOT_HANDLED 0x1000007e ffffffff`c0000005 fffff880`077b2eeb fffff880`035721f8 fffff880`03571a50 MAudioUSBMIDI.sys MAudioUSBMIDI.sys+ba89 x64 MAudioUSBMIDI.sys+aeeb C:\Windows\Minidump\042712-27112-01.dmp 4 15 7601 262,144


    This is on Win 7 x64 SP1, with the the latest 5.10 driver. I'm not sure exactly when the problems started, but they're only with this driver and this keyboard.


    Thanks in advance.

    I don't know how to read the differences in the minidumps, but here's another one


    042812-33025-01.dmp 28/04/2012 01:45:50 SYSTEM_THREAD_EXCEPTION_NOT_HANDLED 0x1000007e ffffffff`c0000005 fffff880`07496eeb fffff880`035801f8 fffff880`0357fa50 MAudioUSBMIDI.sys MAudioUSBMIDI.sys+ba89 x64 MAudioUSBMIDI.sys+aeeb C:\Windows\Minidump\042812-33025-01.dmp 4 15 7601 262,144


    The device isn't recognized by audio and by midi programs, even though Win7 acknowledges the driver as being installed correctly. Sometimes Win7 doesn't acknowledge that.


    I'd also like to point out to a similar problem that has been raised in a different bulletin board, about a different M-Audio instrument:
    http://www.techsupportforum.com/foru...xe-599699.html
    The conclusion there was that the problem is in the driver, but that M-Audio doesn't care much about it. I really hope that's not the case.

    If the problem is in the driver, I hope there will be a fix soon. This instrument is very handy for me.

    The UC33e is plug and play on Windows and will work without the M-Audio driver. Try uninstalling the driver and then reconnecting the device and let Windows install the drivers built into the OS and test to see if you have problems. If the device is not recognized by any applications, see this USB MIDI Keyboard, Controller & Interface Installation Troubleshooting Guide.

    Thanks for your quick reply, right now it works and I hope I won't get any BSODs.

    Didn't realize it works plug and play.
    I guess there's just a problem with the latest driver.
