Re: Comedi compilation problems on Fedora Core 5 SMP (2.6.15-1.2054_FC5smp)

Hi!

Thanks for feeding this back to me. I haven't managed to test with 
2.6.15 but it seems so that hotplug doesn't work any longer. The hotplug 
mechanism starts the script /sbin/hotplug. This is called directly by 
the kernel. There might be a problem with that call so that in case of 
USBDUX the firmware is no longer loaded and has to be loaded manually.
