Despite initial issues, I could finally put my 10 meter USB cable to work. As it turns out, the front USB ports could not provide enough power for this cable; but the ports on the back could.
With that said, a surprising issue has emerged. I can operate my WiFi adapter dongle on the other end of the 10 meter cable, but not simpler devices. My input devices such as a mouse or keyboard should not draw much power. But they aren't recognized; the mouse would light up, the keyboard Num-Lock would not. My USB hub is not recognized, neither is my bluetooth adapter. These two would light up; for the hub the PC explicitly shows up a message "This device is not recognized".
So why is this?
You would naturally wonder why I am attempting to set up input devices on the other end of a 10 meter cable. I actually have an elaborate plan (if not naive). The hub is to harbor input devices and the WiFi adapter, the PC is to broadcast as a hotspot, my Tablet is to connect to the hotspot and a VNC server would allow me to remotely control the PC from the Tablet. The 10 meter cable keeps the input devices within my reach.
