USB keyboard stops working on installation at language selection

I'm installing Ubuntu 13.10 Server (amd64) on a HP Proliant Microserver. I'm using a USB keyboard which works fine until I opt to install Ubuntu and get to the (first) "Select a language" screen. At this point the keyboard becomes unresponsive and the number lock light turns off.

The BIOS is configured to support USB devices in legacy mode (hence I can get past the initial boot screen). Unfortunately the machine does not have a PS/2 port, however I have tried using a range of keyboards to debug this:

• a standard USB keyboard (Microsoft Ergonomic 4000)
• an alternative USB keyboard (G15)
• a PS/2 keyboard using a passive PS/2-USB connector
• and another PS/2 keyboard using an active PS/2-USB connector.

Unfortunately I get the same results with all of these. I note that this has happened to someone else with a wireless keyboard - could this be a case where the installer is not reloading USB devices?

Solution 1:

I found that unplugging the kb and then inserting it into a different usb port did the trick.

Solution 2:

I experienced the same problem. Turns out there was something in the BIOs setting that needed to be enabled.

This is how I found it:

1. Press f2 on Boot to enter BIOs setting
2. When in BIOs, Change Boot order to desired preference (CDboot first)
3. Go to Advance << Chipset Config << USB Device Legacy Support (enable this)
4. Save and Exit

Althouggh every device may be different, the Idea is to look for some setting involving USB devices and ensure that they are enabled during'Legacy' mode.

Hope this helps.
