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?
