Thanks,

The Right hand pane will show you the device info for whatever device or hub you have clicked / selected in the LH pane eg the HUB or the Flash Drive or the Intel Root HUB even
It may show whether the HUB and or Flash Drive both support Wake on Resume etc ie D0,D2,D3 etc

USB Devices get power from the USB port. But many require a separate power adapter in addition. USB Hubs should always have a power adapter attached, and plugged directly into the wall, not a power strip. And the hub should be plugged into the Back USB port of the computer and not the front which has weaker ports.
That being said, USB Mass Storage Devices (ie) USB HDD's, Flash Drives, etc, especially those without power adapters, should be plugged directly into the Back USB port of the computer. USB Mice, Keyboards, Printers, Scanners, Cameras can all plug into the Hub and get recognized.
The Rear USB Ports are soldered to the motherboard. The Front USB ports connect thru a cable from the front port to the motherboard., Because the USB ports are not directly connected to the board, these ports will loose a little power transferring thru the cable.
Same for a Wall port vs a Power Strip, because the strip is going thru a cable to the wall, it will slightly have less power then plugging a device directly into the wall socket. Hubs are very limiting in power, since what should power one device is now plugged into a Hub which wants to power several devices and it has to split the power between all of them. The power loss is minor and most devices won't know the difference, but USB Mass Storage devices are much more sensitive and require as much external power as possible to get recognized, especially with weaker USB ports, like Laptop USB ports which are notoriously underpowered, depending on the manufacturer. Most low powered devices won't have a problem, but if you are having problems with your device, plug it in directly.
I contacted the usb hub manufacturer 1st as I thought it may help and they did have a newer Firmware , which actually didn't help immediately but upon finding out that , they helped me found a firmware update for the built in hub on my motherboard which did get everything working together.
In my search for info I came across the Plugable website , they sell all things USB , so had alot of information on HUBS, as many use the same Chipsets inside so their information is applicable to other manufacturers too.
