Joystick disconnecting constantly during match

[Hitchhiker 42]

Hi,
We (4557) are currently competing at the NE DCMP. So far it has been going well, but we have encountered a problem that can be... problematic at times.

One of our joysticks (specifically a HOTAS of this model) often disconnects during a match (i.e. the driver station stops seeing it). This is quickly remedied by a rescan of the joysticks. Nevertheless, it slows us down somewhat and even prevented us from getting on the batter at one point at the end of a match.

An FTA at our event suggested two options: static building up (in which case, we should ground ourselves and the joystick to a metal beam in the castle before a match) or the USB power saving mode getting in the way (we turned that off). We haven't actually been able to test if either of these solutions work (that was after our last match today), but I was wondering if there are any other possible reasons for this happening. Are there known problems with this like with the Xbox 1 controller?

Thanks for the help.
