Hotspot while charging via USB - Galaxy S III Q&A, Help & Troubleshooting

Hi,
I've been trying to use the built in Hotspot on my GS3, but whenever I plug it into my laptop to have it charge, the Hotspot stops working (i.e. no more ping).
Any idea how to fix this?

Observations about tethering

When using MobilAP, or USB tether, on my Captivate, I could not play a video, or watch a slide presentation at FoxNews. Before applying a stock rooted rom to my AT&T SGS2, I was using PDANet to tether my phone and I could watch both. Now that I have the stock MobilAP(Portable Wi-Fi Hotspot) and USB tethering working on my SGS2, it acts the same as my Captivate. I did find that by enabling USB Debugging, as PDANet instructs you to do, the stock USB tethering will play the videos and the slide shows; however, Portable Wi-Fi Hotspot will not play them.

[Q] cm7 reverse USB tether plus wifi tether to produce non Adhoc?

So, I'm running on the latest nightly of cm7 on my vibrant with a glitch kernel. What I want to do is share my wired connection with my laptop, phone, and ps3 without having a wireless router. The thought is to use reverse USB tethering to put the connection to my phone then use the wifi hotspot ability to share the connection with my ps3. I know the ps3 won't recognize Adhoc being produced by the computer, also it's impossible to receive wifi and broadcast it at the same time. So is it possible to do what I propose?

[Q] Turn on hotspot automatically when connected to Bluetooth

Is there a way to make the hotspot turn it self on when I connect my Bluetooth?
I have a car stereo that I have wifi on, and I use my phone as a hotspot for it. Now I'm wondering if there is a way for the hotspot to turn it self on when I get it my car? The stereo automatically connects to my phone through Bluetooth as a hands free, so can't that be something to use to turn on the hotspot?
Any clues?
