Dualshock 3 randomly disconnecting while gaming

Since not the last update but the previous one, my DualShock 3 is randomly disconnecting every few minutes.
Here is the only Dmesg output :

[ 9610.302877] usb 3-6.1: USB disconnect, device number 9

I tried several USB ports, 3.1 and 2.0 with the same result.

Hmm, is bluetooth an option?

No I don’t have a dongle. Besides it wouldn’t solve the problem.
