I've encountered problems with UBCD 4.1.1 and USB keyboards and mice.
After UBCD has booted and displayed the main menu, the USB keyboard doesn't work anymore... If you use a PS/2 keyboard plugged in a PS/2 slot, there's no problem anymore.
There's also a problem between USB mice and Cute Mouse driver, when Cute Mouse is loading, if a USB mouse is plugged, it crashes and never finishes to load... There's no problem if you use a PS/2 mouse plugged in a PS/2 slot.
I've tried with different models of computers : Compaq Evo D510 ePC, Dell Optiplex GX620 and Dell Optiplex GX745, the same problem occurs with all of them. If you use a PS/2 keyboard and mouse with a PS/2 to USB adaptor and you plug it in the USB slot of the computer, the problem also occurs. To work properly, you must plug a PS/2 input device in the PS/2 slot of the computer.
Conclusion : there's an incompatibility between UBCD 4.1.1 and USB input devices.
While reading the different topics in the "Support & Troubleshooting" section, I've noticed that other people experienced the same kind of problem.

Your tip has solved my problem I've activated the "Legacy mode" for the USB ports in the BIOS and now the USB keyboards work properly in UBCD.
For me it's a big relief because all my machines are linked to a KVM switch, so I can use only one keyboard/mouse/screen for several machines. And now it works normally (before I was forced to use a PS/2 keyboard/mouse for old computers in addition to my USB keyboard/mouse for recent computers).
Thanks a lot !
