Oh, no! It's that pesky fohat.digs again!
A couple of months ago I had a big problem after upgrading a motherboard from Asus to Gigabyte. I keep a powered USB hub at the back of the desk, and my keyboards and mice plug into it. I have done this for a long time, but the Gigabyte motherboard refused to boot (not even a peep or POST) with the powered USB 2.0 hub connected. When I went to a non-powered hub, the problem disappeared.
There are USB 2.0 and 3.0 sockets on the back, and since I have a 3.0 external hard drive, I wanted to upgrade the USB hub. I bought a nice SIIG 4-port powered USB 3.0 hub, and plugged it into the (previously vacant) 3.0 port.
Now, the computer boots fine and recognizes both of my mice, but will not recognize my F-122/Teensy (Teensy 2.0 with v1.10 Soarer's Converter) until I unplug it and hot-plug it. I have been through several power-up/power-down cycles and it is still happening.
I know that motherboards are funny about these things, sometimes, and the stock answer is: "plug the keyboard directly into the motherboard" but I would prefer to make the hub work if I could.
Are there any new answers since last time?
Thanks! Harry
