Im having the same error i have a hd pod400 i have probably plugged a usb cable into into the hub about 10 times total. About 4 months ago i started recording to my computer by plugging directly into the pods usb port i was using audacity DAW software and had no problems recording as well as when i plugged into the usb for software updates. I purchased cubase 7.5 DAW about 2 weeks ago and could not get it to recognize the pod, after trying everything for 2 days i finally went back to the old recording software and even that wont recognize the pod now. I then opened Monkey and that wont recognize the pod through the usb either. Im going to talk to support and fill out a ticket unless any one has any other ideas thanks
