I'm looking at getting 2 for my laptops and I thought I tried one once and it didn't work. Newegg.com has 4 port hubs for $5.99 each. Any problems with them in your experience!?! Thanks...

Mike,

I've been using a Linksys ProConnect USB 2.0 4 port hub for a couple years now without any issues. Really helps when a lap top has only 2 or 3 ports and more are needed.

I've had one for years. They do need to be powered though. Maybe that's why the one you tried didn't work?

Why do they need to be powered if the device you plug in uses the power off of the USB bus...

I'm guessing that the computer USB's output gets too diluted to run 4 devices.

I'm sure you're right. On my old Gateway, the USB ports are too close together and I need something with a little more space between the ports. My scanner may not work, but it's powered by the USB bus and not AC, it should. Oh well, we'll see...

Mike,

I don't think going with a self powered unit that will be asked to handle up to 4 connections is a safe bet. I noticed that the reviews for the one you linked at Newegg implied it didn't function well when all the ports were filled. Why get one with 4 ports if you can't use them all? Hell the LinkSys is just $29. That's not the $6 that the self powered one you linked costs but for the few additional bucks you'd have reliability :)

Pros: ..
Cons: If you look at NewEggs excellent photos you'll note that the LinkSys USB 2.0 Four port Hub is powered by a wall adaptor. Unfortunately, all the power adaptor does is power the internal hub. No extra power is supplied to downstream devices from that Adaptor. So no plugging in your mp3 player and expecting this unit to recharge it.
Other Thoughts: So if you don't need to power downstream devices (lights, fans etc) buy one that doesn't need power supplied from a brick!

I've been using a USB hub for years. Mine are Belkin. Prolly junk but they get the job done. Mine also works via IR so my laptop can print w/o being connected via hard wire. I looked on the Belkin site and it doen't look like they still make that model. I did see a wireless USB hub which is pretty neat.

Mike,

I think that reviewer you cite is full of it. The pdf here http://downloads.linksysbycisco.com/downloads/USB2HUB_V10_DS_B.pdf
shows 500 mA (Maximum) per Device Port. If you look at non-powered hubs, most are restricted to 100mA (USB 2.0 defined "unit load"). Bottom line is that the wall wart ensures additional current capabilities to all ports that a non-powdered one can not.
