Then i would question your psu Earl ?

Goto Device Manager and expand the + sign next to universal serial bus controllers ,right click usb root hub/properties/power management and if the box (allow the computer to turn off this device is ticked,untick and ok.

Under the power tab;
What is the available power per port ?
You should be seeing something like 500mA per port.

I have several (6 or 7) devices running off 1 Usb port, Do I need a powered USB hub ?

You should get a powered hub, each usb port will then have 500mA per port available for device useage.

Running multiple devices from one usb port can be problematic, specially if you use a given number of devices at the same time, whereby the total amperage required by those devices exeeds, or in some cases approaches, the available 500mA per port.

Installing a powered hub seems to have corrected the
