Title: A20 and hub usb to have more than two usb
Post by: artone on June 18, 2016, 05:49:43 PM

I've used USB hub with my A20-Micro without any problems.
Try with a different hub, the current one is maybe the culprit.

In my case, simple chinese 4 ports USB hub found on eBay worked.
"lsusb" was showing them as "Genesys Logic, Inc. USB 2.0 Hub"
