Can you provide extra 3.3v power through the USB port on the EXP GDC BEAST? Can I just connect a male to male USB cable from my notebook to the BEAST?

Hey guys, Ive got a strange situation which I cannot explain. My setup is a Gigabyte U2442V with a GT640m dGPU and a HD4000 iGPU. 3rd gen i7 with HM77 chipset.Windows 8.1 64bit. Im using a pci-e exp gdc beast with a dell da-2 to power a GTX 680. I have been able to get the system running in windows without any issues, Ive played a few games and have no issues at all. Through the bios I am able to disable the dGPU so that windows only sees the iGPU and the eGPU. My problem is with the initial startup. When I first cold boot my system it immediately powers down, you can hear the hard drive make a noise as it immediately turns off from a high spin rate. It then shows the post screen on the laptop display. I now have to enable the dGPU and save changes and restart. It then restarts all by itself, powering down and making the same hard drive noise again. It shows the post screen and I go into the bios and turn the dGPU off, save and restart. This time it does not suddenly power off and there is no hard drive noise. It reboots without cutting the power off with the eGPU working. This procedure works every time and does not appear to be related to a time delay of any kind. I have installed Setup 1.30. Before I installed Setup 1.30 rebooting, shutting down(fastboot) and shutting down(normally) would mean that I would have to repeat the above procedure. Now it would turn on as normal from a shutdown or restart.Also sleep did not use to work, waking from sleep with the eGPU would result in a BSOD. Sleep works now. But if I shutdown or try to wake from a sleep after a few hours, even if everything was left plugged in, it would result in having to repeat my bios procedure above. Also waking from sleep would BSOD just like before I installed Setup 1.30. Finally Setup 1.30 can only see my eGPU once I do my bios procedure above. I have tried saving and restoring ports but it doesn't seem to work. Also hotplugging, (removing the hdmi end of the pcie to hdmi cable and reconnecting), in Setup 1.30 or F8 windows halt does not work. The only way I have gotten it to work is with my bios procedure but using it this way would mean that i need to leave my laptop on all the time or have to deal with hard drive damage due to the sudden power offs that my procedure results in.
