Simultaneous Power Supply Advice

[Campin Jay]

I've been struggling with random disconnects.

Azeron keypad and a mouse dongle --> Powered USB Hub --> Xim Apex --> T2 Powered with 7.5V --> XSX

Is that proper? I'm not sure if my stability problems come from a loop, or maybe the voltage difference of 2.5V creates a gradient across different power buses. Any advice is appreciated.

Once I knew it was my fault because I felt a static discharge against the base of the Azeron as it disconnected. But most of the time I'm just going along, mid-game, and the X-box says Please Reconnect Controller. Of course there's never an opportune time for this to happen, lol.

You don't need have 2 external source of power. You can choose power the Titan Two, or use the powered USB HUB.

Despite the input voltage be 7.5V, internally the Titan Two regulates the USB voltage to the standard USB 5V.
