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 ?

thanks

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.

to all that responded;

Installing a powered hub seems to have corrected the
problem.

Thanks again
