Issue After Reboot

It's because the udev rules don't work in RHEL/CentOS which are supposed to create a symlink in /dev/entropykey that the default ekeyd config is looking for.  One way around it if you are only going to use one key in the system is to change /etc/entropykey/ekeyd.conf to have a line "AddKey /dev/ttyACM0" rather than the default one of "AddKeys /dev/entropykey".  (Make sure to put the device path in quotes.)  This avoids the whole issue of udev not creating the link on boot.  Maybe one of these days I'll fix the udev rules.

Subject: Issue After Reboot

I received the entropy key recently and I've been generally impressed by it. One minor question that has come up is whether the USB driver fails to detect and connect to the device after a reboot.

I'm using Centos 5.4. If I perform a reboot with the device attached to the computer, then it doesn't seem to work properly. The 'ekeydctl list' command shows nothing running after the reboot and "entropy_avail" is low. On the other hand, if I plug in the device after the boot up completes, everything works normally.
