I have a brand new XPS 15 9560, which finally came in the 28th of November. However, I currently experience problems with the right USB port. When hooking up an external HDD, it keeps connecting and disconnecting. At first, this rendered the HDD useless, setting it to a RAW format and losing all data. I got it back to work eventually and was under the assumption that the drive just went bad. However, i started to have the same problems with my alternative drives when connected to that port.
Narrowing down the problem, I found that the left port maintains a steady transfer speed of 122 MB/s ish, while the right keeps powering up and down. This means that data transfer wil go up to 60 MB, drop down. The disk will reconnect and the same happens. Remark: There is no sound of a physical re-connection (the well known connect/disconnect sound).
Furthermore, i have found that multiple people have this issue:

I also followed all directions given within this topic, but the problem still persists.
Do you have any other ideas?
