Hi Mach6,
Thanks very much for the informative reply!
I managed to fix the issue for the USB3 driver by following torpedor's advice and assigning it to the 'USB Root hub' (thanks).
I am still having a problem with the fingerprint drivers unfortunately. I can see in the HIIClient.log that it recognises that my driver package needs to be downloaded but it fails and nothing installs. I will attach a pictire of the log as I can't figure out how to attach files (by the amount of information you replied with I think you will be a lot more helpful than LANDesk support!)
Thanks,
Peter
