V-USB AVR Devices (virtual usb) - MIDI NOT GOING THROUGH

Hello there,

We’re trying to connect v-usb avr device to Oplab, it doesn’t receive MIDI signals.
The device works with any operation systems (iOS, MAC, WIN), but Oplab doesn’t want to be friends with it.

Please help.
Thank you.

Hi Andrey,

Looking at the v-usb website, this may be a clue:
"Fully USB 1.1 compliant low-speed device, except handling of communication errors and electrical specifications."

I haven’t tried v-usb, but my guess is that they came up with something that maybe isn’t fully USB compliant but still works with most computers. If it doesn’t follow the USB electrical spec, there may not be much we can do about it, but let’s give it a try.

I’ll reply to your email support request with some follow-up questions to troubleshoot this. I’ll keep the forum posted if we find a solution.

Best, TE

If anyone else has got a v-usb device working with oplab, please let me know in this thread.
