Topics About this product: 7 Port High Speed USB 2.0 Hub with 3A Power Adapter
I have this: Plugable USB2-HUB-AG7 7-port USB 2.0 Hub with 3A Power Adapter
(correct me if I am wrong) When a host PC is attached and this hub is properly connected to a regular AC outlet, up to 6 connected USB devices are each supplied with 500mA of power.
(correct me if I am wrong) The red LED light on this device indicates that the hub is receiving power, either 500mA from the PC (upstream USB port) or 3 amperes from the external AC adapter. So the red light does not tell me if the device is supplying full amperage to connected devices. If 7 devices are connected and this hub is not connected to an AC outlet, it is possible for the red light to be lit but each device is receiving less than 100mA.
Here is my problem: Sometimes connected devices seem to be starved for milliamperes. I suspect this problem is intermittent because sometimes the power connector becomes loose and I do not notice it (again, because I am seeing a red light all this time).
Question: Please recommend some sort of handy-dandy way that I can quickly determine how many milliamperes are being supplied (by a port on this device) to connected devices.
I found this:
Question: What do you think? Can you recommend another device better suited to this purpose?
