Hi Rob, It really is strange behavior; I can understand being at a loss. I have been able to force XP to reinstall by first uninstalling the driver using USBDview, but that by itself made no difference. But maybe the new firmware will make a difference. I'll give the beta firmware a shot, assuming t...

The multiple copies is probably because you've plugged it into more than one USB port and has saved multiple copies of the driver. That's true, but does not account for all instances. I say this because I used USBDview to uninstall ALL drivers, then plugged in MIDI Expression into just one port, an...

Yes, USB confuses me because it seems to be implemented in layers, with each layer being shown as a "device." USBDview seems to show only one of this set of "devices" as connected. USBDview does not explicitly show any relationship among the set of devices. I used USBDview to &qu...

I got the USBDview.exe utility and dumped the USB info for MIDI expression devices on both the Dell Mini (which works) and the Dell D620 (which doesn't. But needs to.) In each case, the device was connected to the machine. (I could do a full dump like this of all devices, which might reveal somethin...

I tried it on another laptop (Dell Mini) and it works: MIDI-OX sees it and shows the CC values as I rock the pedal. But I need it to work on the D620. Is it possible that of the various USB MIDI devices I have installed on the D620, that all ports have been "claimed" (registered) as belong...

Windows XP Pro Service Pack 3. Dell D620 laptop.

For example: when I start MIDI-OX , it throws up an alert: "There are no MIDI Input devices."

I will try it on another machine to see what happens.

I plugged in MIDI Expression to the USB (Dell XP SP3). As the plug and play driver installed and I saw messages like "MIDI Expression Orange". I plugged in an expression pedal. I opened MIDI-OX, but it saw no inputs (MIDI sources). Same with Transmidifier. Same with VSTHost. I tried other ...

FINALLY. The world has needed this product for years! I just ordered one. I thought I'd write this note before I forget to. My use case: pick up band at the annual SMPTE engineering tech show in Hollywood. I can't take my USB keyboard on the plane, so last year they bought an Oxygen 61 for me to use...
