Class Compliant USB

Hi Luiz,

They are not kidding about having the USB device hooked up and recognized by the Operating System *before* attempting to open any software that addresses the device.

Most softwares go through a routine that looks for available MIDI devices when the software is started.

That means that the USB device must be hooked to the computer while you are still looking at only the desktop, with NO music softwares that use MIDI open or even minimized, they must be fully closed down when attaching the device. Wait for Windows to recognize the device, sometimes difficult because there might not be a popup to tell you such after the first time. Then and only then, start the music program.

One more thing, it is always best to remember the physical USB slot where you first connected the device and always plug it into only that slot in future, or Windows may install a new instance of the driver for each physical slot. Which may not hurt anything, but sometimes can cause problems.

Keep troubleshooting the problem, with your engineering skills I'm sure you will note a clue that will expose the nature of the problem and thus the solution!

And send me a few barrels of that OIL! *grin*
