Query: Check your PC's device manager before you buy this

This device will not work if your PC has the Intel BA/BAM USB controller, so save yourself a major headache and check your PC before you buy. How do you check? Right click on "my computer" click on the "hardware" tab, click on "device manager" then look under "Universal serial bus controllers" and see if the one installed on your computer is a version of the Intel BA/BAM. the problem may be with the Viking device or with the Intel controller, I'm not sure, but I'm giving this device 1 star becase A) This info should have been posted and B) when I talked to tech support at Viking and said "you should post this info" they basically said "not our problem" which I thought was rather unhelpful.
