I have also found usb less troublesome, the problem seems to be the bandwidth of usb2, im experimenting just now with dedicated n wireless network just for the video stream. I use limelight as i have an nvidia card, around 30mbps seems to be a good rate of transfer, but im still testing. It really has came on alot in recent months, Colourcross is an even better headset once u try a few different optics in it. The phones firmware/software is a big part of the problem, streaming progs use alot of gpu so having access to the system kernel on phone, aswell as dpi and refresh rate can give you more breathing room.
