Firstly, tried with a Microsoft natural keyboard 4000 v1 and a Logitech G5 mouse. But even through the usb hub it cant power those two peripherals.
1) Does it power again?
A) No, I have to disconnect the XIM edge so it powers down and then reconnect.
2) Do you need to unplug it?
A) The keyboard, mouse and controller becomes completely unresponsive. The mouse for example has a red light where the sensor is. But after the error, this turns off. I literally have to unplug the Xime edge and reconnect. And in about 30% of the times, the mouse, keyboard and controller starts again and I resume control of my ingame character.
3) Any lights on the devices running?
A) The xim edge pulsates in the color chosen for the particular game, in this case blue.
4) First, do you have any issue with only your DS3 plugged in through your Edge?
A) No, I just played through an entire Black ops 2 match without a single glitch with just the controller connected to the edge and the edge connected through a USB hub and into the Sony Playstation 3 slim console.
5) Does it stay on for more than 5 minutes?
A) Yes, worked with just the controller. No issues.
6) Also, are you sure your DS3 is already fully charged?
A) According to the Sony Playstation slim menu it seems the controller is fully charged.
7) Are you using a long USB cord for power / connection to the ps3?
A) Standard one meter cable. Im sitting at a normal office desk.

Which PS3 do you have? Slim? Fatty?
A) Sony Playstation 3 slim - model number CECH-2004A
9)HDD Size?
A) 120 Gigabytes.
10) What video connection are you using? Composite? Component? HDMI?
A) HDMI
11) What audio connection are you using? RCA? HDMI? Optical Out?
A) Optical out
12) Does your XIM Edge plug directly into your PS3? Or is it powered through a hub?
A) Powered through hub, because when I plug it directly into the PS3 slim, it simply shuts down the controller, keyboard and mouse directly.
13) Do you use a USB headset?
A) No
14) Do you have other USB devices connected to your PS3?
A) No
15) Are you using the standard PS3 controller cable?
