Hi @Anonymous User
I would have thought any Male Micro USB to USB 2 cable would do the trick.
You may have one laying around the house somewhere off an old phone, tablet, electronic device etc.
Here's on example from Ebay linked below approx 1.5m long (doesn't need to be 90 deg angle left or right unless the space between the back of the TV HDMI port and the rear facing wall is tight for space).
Shop around places like Amazon or Ebay and i am sure you will find a cable cheaper.
