I need a powered USB Hub, 7 (or more) ports.

Lots of conflicting reviews out there.

What do you fellow lurkers recommend?

Thanks!

Since USB is so, um, universal it's not surprising to find a
manufacturer who keeps model numbers and prices the same but has changed
the chip(s) inside which may noticeably change performance,
unfortunately. I.e., the popular D-Link DUB-H7
(http://www.amazon.com/D-Link-DUB-H7-.../dp/B00008VFAF)
has been around for at least 5 years now, and has gone through multiple
internal design revisions.

What do you fellow lurkers recommend?

I have one of these that I like:
http://www.newegg.com/Product/Produc...82E16817182208 --
pretty inexpensive and it "works fine for me."

Note that very few hubs -- almost none once you're above 4 ports --
comes with a power supply beefy enough to provide a full 500mA to all
ports; I've often felt that the ratio of the power supply's current
output to "number of ports multiplied by 500mA" gave at least some
indication of the quality of the design. (I.e., if they cut a bigger
corner with the power supply, they probably made bigger cuts elsewhere...)

Manufacturers do this, of course, since it's incredibly unlikely anyone
would actually have, e.g., 10 peripherals that all truly need 500mA on a
10-port hub, so they save money with a smaller power supply.

Good direction pointing, Joel!

Consider a powered USB 3.0 Hub? I see that they are not that much more
expensive.
Anyone know of problems with these?

I have one of their USB-1gbs Ethernet adaptors. Its made well, and
works. (although USB is only good for ~200mbs)

Really? I thought it was 480mbs? That is, the main port..

Get a PCI card that adds USB functionality.

I was all set to buy a hub when I came across a computer lying on the
sidewalk, and it had a USB board inside. No need for a hub after that,
but I do get more USB ports.

Of course, if there was a special reason for a hub, you didn't mention it.

Let me know when you find some four port low profile USB boards
laying around, for salvage. I need two.

Eeek, Senior moment? Well, I sure didn’t get the full 667mbs
theoretical thruput, but is was somewhere around the USB port speed.
Which must have been ~400mbs, not 200mbs. I should check it again. But
the point was that it worked with out a hitch.

'Cept for really cheap crap, i haven't had any hub problems.

You may wish to get some USB 3 hubs, but they are never more than 4:1.

Not a lurker, i post.

If you can't get 'em for free (and shipping is never really free), these

That's not low profile. I bought two of these from another seller.
Three weeks later I got an e-mail stating that the entire shipment was
defective, and they refunded the money.

This is interesting:

http://www.ebay.com/itm/200698468108 I've had computers with dead USB
ports because of bad drivers and no way to update, since they had no
PS/2 ports.

Wow, that is.

I guess there's a lot of those "industrial" keyboards (either ruggedized
or with extra keys or whatever), barcode scanners, etc. that have PS/2
interfaces and aren't going away any time soon? So on new builds it
ends up being easier to stick in a card like that than to pick from the
small number of motherboards that still have PS/2 keyboard/mouse support?

I've seen plenty of PS/2 to USB converters for keyboards and mice, but
for industrial PCs I can see that a PCI card might be a bit more attractive.

There are gender flippers both ways.

The difference with this card is that it goes under the PCI bus and
gets an interrupt assigned to it as in the legacy method and will almost
always underlying OS support, whereas a USB to PS2 device will not get an
interrupt and *has* to also have underlying OS support for an HID device.
