the man says so, lol.
I looked up the most recent regulations on USB devices, which is very lengthy, and it directly states devices that have not been approved cannot be used in the network.
plus, i tried a year ago with a ducky 1087xm, and they seemed weirded out by the brand and chinese letters (probabaly thought i was a N.Korean spy haha). But oh well, my loss is someone elses gain? Although they don't seem to be moving. Is my pricing off? I thought it was a bit below normal, maybe im wrong?
