Hi, all! I formerly had a 4-port non-powered USB hub connected to my Surface Pro for desk use. Attached to it were an external hard drive, DVD drive, thumb drive and wireless keyboard/mouse receiver. It worked fine, but I wanted a few more ports for occasional additional thumb drive use, etc., as well as a different form factor better suited to a more convenient location a few feet away from where I keep the Surface. I bought a well-reviewed Amazon 7-port powered hub and a 6' USB extension cable. I initially connected the new hub directly to the Surface without connecting the power supply. All four USB devices worked just fine even without external power. I tried to use the USB extension with a regular USB cable and charger to charge a separate Acer One 8" tablet but it took FOREVER to charge, which I later found is common, as there is a significant voltage drop. But that's not really my problem.

I relocated the new hub and connected the power supply and extension cable. Now my wireless receiver, DVD drive and thumb drive work just fine, recognized and accessible by the Surface, but it can't see my external hard drive. If it was a non-powered hub I would say that the Surface didn't supply sufficient amperage to power the drive over the extension cable, but given that the DVD drive works just fine and that the hub is powered and that all four devices worked just fine when connected directly to the Surface, I have no reason to suspect the Surface, the extension cable or the HD to be the culprits. Which means I am out of suspects! LOL

Any thoughts? Thanks in advance!

Looking for the hedge trimmers and wondering

if a kitchen blender would work,
