    Supply additional power to your DVD drive. These drives use over 1 amp. I know my slot load requires1.6 amps. Anything less and it doesnt work or works very inconsistent. It is probably robbing power from the other devices causing them not to work.

    I have the same problem as Lukeyson. When I connect my slot-load dvd drive to mobo's usbs (using 2 usb cables: one for data and one for power) it works just fine. If I try to stick usb extension cables between the pc and the dvd - it won't work. I tried different usb extensions: cheap, expensive, repeater. Nothing worked. I also tried the powered USB hub, but that did not help either. The dvd was the only device connected to that hub.

    u need a hub that has power protection or port over-current protection, in my post #6, this hub was the only hub that worked with my pc. i've tried all the others and they failed.

    i have my slot load dvd drive plugged into my pc on 1 of the 2 ports, and the hub of other, and everything works perfectly without external power.

    did the hub u buy have individual port current protection?

    I connected the external 5V directly to the DVD. The 5V being enabled by presens of USB5V. My DVD is 10W or 2A (panasonic slot-in). Works fine.

    Problem was to find a 5V supply, as a normal linear regulator would generate a lot of heat. Only found the Opus DCL11 (15W), that was 100$ ot get to Sweden including custom tax! But its a great device.

    I have a 7 port Inland USB powered hub that supports 500mAH ports for charging cell phones. I have it powered off the 5V line from my M4ATX-250. Split one of the power connectors, the 5V line powers the hub and the 12v for my LCD.

    You'll have to run the touchscreen overlay directly to the computer anyway, I doubt it'll be recognized in a hub.

    I'm using my Eee Box computer with the micro startup/shutdown controller in combination with a universal 12v voltage switchable laptop power supply. The power supply has a built in 2 AMP 5V USB port. I ran a USB plug from that port to the 5v power input of my powered USB hub, works great. Before, when I'd plug the USB from my iphone into my car's computer, it would drop connection randomly, now it's been perfect.

    Wow. Ask and ye shall receive.

    That's almost enough to encourage me to re-engineer my solution to not require a 7 port USB Hub.

    ...if it weren't for the $50USD shipping fee to get it to Australia.

    I've been discouraged from purchasing items from MP3Car in the past because of high shipping costs.

    Oh well.
