Crappy USB MiniB plugs, 5506

I have recently taken delivery of 4 ASA5506X NGFW boxes. What is with the USB console connection? All 4 are barely useable, the plug has to be pushed in, and held to function properly. It seems to not be going in far enough to make a reliable connection. Since these devices all need to be reflashed, this becomes tricky. Took me a while to figure out why I could not connect to some devices.

Have I just got a bad batch or is this a design fault?

Is there a "MarkII" cable, or some case modification that allows a positive connection?

I have only ever used generic

I have only ever used generic USB cables to connect to the USB console and I have never had an issue. Go and buy some cheap cables and I suspect it will work out.

Tried that, not really much

Tried that, not really much different. It seems that the PCB is too far away from the rear of the case, hence the USB cable cannot penetrate enough for a reliable connection. Some devices and cables are worse than others; the best firewall and cable work OK, provided the table they are on or the cable are not bumped. The worst require constant force on the cable to work, either holding it in with one hand, or jamming it against some object.
