Hello & Welcome to Just Answer,
Sorry to hear of any trouble you may be having.
May I ask:
1) the AGE of the device (I see you mentioned "new", but I need to know how new & how long you have owned it)?
2) If you have connected it to ANY other power source - besides the computer?
3) Do you have a model number printed on the back of the device, and if so, can you send that along?
I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved.
I look forward to any further questions or results that you may have.
Thanks, ***** *****
