"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.
