If you have this scanner plugged into a USB 3.0 port or hub, take it<br>
out and plug it into a USB 2.0 (black port) port or hub. I've found<br>
the LiDE's up to and including the 220 (which is what I have) are<br>
fickle with USB 3.0. This may also be a function of the motherboard<br>
in your PC, because I had the same issue on numerous PC motherboards<br>
except for what I'm running now, an Asus TUF Gaming B550M-Plus.<br>
