Solved USB hubs inside delivery truck sporadically drop connections

January 8, 2016 at 06:56:32
Specs: Windows 7
we have to unplug then plug back in the usb cable and it works...my customers are getting very frustrated. Is there a USB hub that doesn't have this issue? We are using a powered star tech hub

I am visualizing the driving around over uneven roads causing a lot of jarring around of the hardware. Consider that the hub itself is being bumped as well as the hubs USB jacks and the USB plugs on the cords are being moved around. Try first different USB brand cords because a few of the better ones have snugger fitting connectors that will tolerate this better than the cheaper ones. Then bundle wires and use tie downs to keep movement to a minimum. If this does not work then try a different brand hub and add some cushion to its mounting. I would also recommend adding a small UPS (battery back up) between the inverter and electronics to better smooth out the power being supplied to the electronics as voltage spikes and valleys during starting and stopping the engine could be causing issues.

You have to be a little bit crazy to keep you from going insane.

the unit is inside a delivery truck and the power runs thru an inverter hard wired to the ignition fuse. When we unplug then plug back in the usb cable it always works but is frustrating to our customers

I'm not sure about what you are describing.

Is this about a Windows 7 computer?

If so, are you saying that it suddenly stops for no particular reason and can only be fixed by unplugging and re-plugging the USB connection?

Always pop back and let us know the outcome - thanks

Inverter? You mean 12VDC to 220VAC?
have to tried one of these cigar-lighter-USB-chargers that produce 2A output at 5VDC?
There maybe a need to adapt the USB cable to power-banana-plug at one end.
In my opinion a much more stable power source than the inverter.

Is this unit a USB3.0 version? Try the USB2.0 connector on the laptop.

I'm having a hard time visualizing this.

These delivery trucks have USB hubs installed. A USB cable is plugged into one. What is the other end of the cable plugged into? That is, what is the hardware that's losing the connection?
