I don't have this to test, but it seems plausible. If you plug in the yubikey first and then attach the true keyboard, does the real KB fail to work?

Yubikey not recognized in pre-boot

2010-08-18T11:51:54+01:00

We've recently got a report from a user who uses the Yubikey for TrueCrypt. When the Yubikey is attached to a docking station together with an external USB keyboard, the Yubikey is not recognized. Removing the USB keyboard makes it all work. A second attached USB keyboard does not work either. Attaching a PS/2 keyboard is ok.

To me, it seems like the BIOS only recognizes one USB keyboard (the first found probably).

The user has HP 2540P, 8440P & 8540P laptops.

Anyone seen a similar behavior in any other setup ? Anyone with this laptop family that could try this setup ?

Thanks,
