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,
JakobE Hardware- and firmware guy @ Yubico
