Hi, I've bought a 2nd hand 5500PACA that appears to behave normally from toolkit and piced when I connect via CBUS, i.e. I can push a new schedule to it via cbus and get no errors. However the schedule never runs from the PACA, it does run from piced on the laptop and the CBUS time is set correctly (checked via a DLT). I've tried to reset/recover the paca but can't connect to it via usb, it's shows as an unknown usb device. I've reinstalled toolkit a couple of times and selected "force install drivers" but that hasn't helped. Any ideas or pointers to where I can find the windows drivers and manually install them? thanks!
