I am experiencing constant high cpu usage as soon as I plug my UD-3900 in to my laptop USB slot. It is a USB 3.0. I found a support case from a few months ago where one of your other users was experiencing the same issue. I went through the steps that the Plugable employee listed but unfortunately I still have the issue. Is this a windows issue or a Plugable issue? My laptop runs completely normal when not plugged in to the UD-3900.
