Issue After Reboot

I'm thinking of trying the key with a newer version of Linux as well. I recently installed Centos 6.1 under a Hyper-V virtual machine; unfortunately,  Hyper-V doesn't support passing through the USB device to the guest OS. I'll find some time soon to install Linux on a physical machine and give it another go.

FWIW I'm using Gentoo Linux and it works fine for me after rebooting.
The Gentoo ekeyd package has some patches, especially to the udev
rules and scripts, maybe you will find something in it that is useful
to solve your problem. (note they have patched it to use
/dev/entropykey/ instead of /var/run/entropykey/)

I'm using linux kernel 3.1.7, ekeyd 1.1.4, udev 171.

Here's the patch:
