Subject: [9fans] usb: keyboards vs. hubs
Topicbox-Message-UUID: 5855d452-ead2-11e9-9d60-3106f5b1d025

What is it with keyboards plugged in to USB hubs that the kernel doesn't 
like?  I thought it was just a broken hub when I first noticed this, but 
now I've seen it on two completely distinct systems.

If the keyboard has anything between it and the CPU (e.g. a hub or KVM)
it doesn't work.  Yet on the exact same path, a USB mouse works just 
fine.  In at least 50% of the cases, the same keyboard directly attached 
works fine :-P  Am I just in a vortex field?
