Comment 40 for bug 433438

I'm having a similar problem after an update I installed this morning I'm running Kubuntu Lucid with kernel 2.6.32-24-generic (64bit)
In my case the issue involves my usb mouse and keyboard. I've checked and the keyboard an mouse are working in the bios but then are deactivated when linux boots.

As a workaround I've had to add a ps2 keyboard and mouse to get past the login screen. Then if I wait a couple of minutes the mouse ad kbd are enable.

Based on the syslog (att.) it looks to me like the usb HID drivers aren't being loaded until a bit more that 2 minutes after I begin the boot process.
