Hi guys...my setup is as follows. I have dell laptop with only 1 usb port . I am powering it thru my cig lighter with a targus adaptor. It is placed in the back seat under the passengers seat. Now, I have the tm-701L touch screen which requires a USB port and I also have a TV tuner and fm radio tuner which require a usb port. I bought a 4 port usb hub, but if i don't attach the adaptor which plugs into the wall, my tv tuner and fm tuner won't work!! I guess the power from the single usb port in my laptop is not enough to power all the peripherals without external power. What do I do!! it's so frustrating?? Can i cut the ac adaptor and connect it to 12V dc power????? Please let me know!! Thanks. Any battery powered usb hubs????
