Error: No USB KB Input Device

Aguden · 12 Oct 2014

I installed a Superspeed USB 3.0 7-port hub since I was about out of USB ports. I moved my mouse, Wacom tablet and a Logitech portable keyboard (keyboard #2 that I use when I am using the Wacom tablet for photo editing) to the 7-port hub and plugged the hub into power and a USB 3.0 port on the W7 PC. When I restart the PC, I come up to with:

ERROR: No USB KB input device. Strike the F1 key to continue, F2 to run setup utility.

Useless advice since it can't find a KB!. In addition the the wireless KB, there is my regular KB, and all has worked fine until the Hub. Neither KB is active when this error appears.

If I turn the power off, the PC boots normally but as soon as I try a restart it comes back with the error. I am wondering if anyone has an idea od a way to get some of the additional ports I'm looking for. The mouse and Wacom seemed to work fine and it looks like the dual KBs may be the problem. Any USB help would be appreciated.

Having worked with a number of computers my experience is that the USB keyboard and mouse must be plugged into USB ports on the computer, not on a Hub. Adding to the issue is the limited power available in the onboard USB ports, a Self-powered Hub is best for most other devices. Some computers of a few years ago used to need the mouse and keyboard plugged into ports nearest the power supply, gives the appearance that those ports get power before the others. I haven't had occasion to check if the mouse and keyboard work with USB 3.0 but can say that an HP printer plugged into a USB 3.0 port would quit printing after about an inch of date with an error of lost communication, plugging it into a USB 2.0 port gave no problem [nice to have light when working under a desk].

The BIOS is generating the error when booting and from a practical standpoint is not seeing the USB Hub soon enough.
