Best mountable, DC powered USB Hubs?

**Dan Marsh** · 12-26-2003, 06:33 PM

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

I bought one off newegg that use 5v, but 2.4A!

off the shelf at comp USA I got a usb 2/1 that runs off of 5v DC. 1 inch square of velcro and dazam! 4 more usb ports.

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.
