  • Best mountable, DC powered USB Hubs?

    I have an EPIA board and it only has two USB ports and with the ever expanding number of peripherals hooked into my computer I am in serious need of some USB Hubs. Several of my devices (USB HDD, USB 802.11b adapter, etc.) take up pretty much all the power that a single USB port can supply, so hubs that get their power from the USB port are not an option. I also am running off DC, so wall-wart powered hubs are not an option. I have managed to power several peripheral devices that would ordinarily run off bricks by using the +5 and +12 volt lines of the molex connectors coming off my power supply. Both of the USB hubs I have tried require unusual voltages (7.5 volts). So, anyone have any ideas on how I can get some powered USB hubs to work in my car? I would ideally like something that can easily be mounted.

    I have a USB2 hub which IIRC said it needed 6V. I hooked it up to my 5V from the PSU, and it is working, powering a USB GPS, and a USB2 to IDE adapter for my slimline CDROM drive

    Check for some more USB hubs, there are some out there that run off 5ish volts

            Yes, I know that there must be some out there that work, but saying so doesn't help me any. If you have something that works reliably off the 5 of 12 volt lines of a molex connector, could I please get some brand/model numbers. I don't want to just go around buying USB hubs until I find one that works.

              This is what I bought, works perfectly off my 5V line: http://cgi.ebay.com/ws/eBayISAPI.dll...tem=3054173165 . It has four hi-speed ports and is the smallest powered hub I could find for cheap. They are now 3M stuck in my glove box. Just search ebay for "Mini USB 2.0 HUB" and you'll find a lot.

              I didn't know that they even made 7.5V hubs, that's is rediculous in my opinion. It must be regulated internally to 5V.

                Have you guys checked this out ?? Seems like a cool idea, and with a little ingenuety you'd be able to mount or modify it not to expose the guts...

                it seems to take power from a floppy drive power hookup...

                  thanks for the link. I wouldn't be suprised if closer inspection of that board reveals it to be using just the 5v or 12v... both good for what we're talking about :-)

                    I really like the looks of that one from siig, particularly that it takes a floppy connector. I think I saw one like that at Fry's once, so I will check there in the next few days.

                        Will this work, it sais it's powered via the USB Hub and has per port overload protection, but I wonder weather that hub would support say 4 Mobile USB2.0 DVD ROM drives... (Powered off the USB Port) Not that I need that many but as far as power draw goes I wonder .... :scratch:

                        Than again for under $10 ... we'll see... And there's other auctions for that price too

                            Not directly related but I purchased on of these cables

                            http://linitx.com/shop/product_info.php/products_id/323

                            Its converts the mini-usb connector for the 3rd and 4th USB ports on the Epia MB into a normal MB connector. Its works a treat with the front connectors on the 3688 case I have meaning that I've now got 4 usb sockets all able to give out the full 500ma.
