StarTech.com 7-Port Metal Industrial SuperSpeed USB 3.0 Hub Rail Mountable (ST7300USBM) Review

This box is top notch as far as quality - the box is black painted metal with mounting flanges, and comes with little metal clips for mounting to a rail. It comes with a male-A to male-B USB 3.0 cable for attaching to your computer.

However, be careful! It does *NOT* come with a power cord, and Startech does not make, sell, nor suggest anything as a solution! After a chat session, I found that to fully power the 7 USB 3.0 devices, you need a AC to DC power adapter that outputs 40 volts and 6.3 amps. I've searched all over and haven't found any solution - there is no laptop power adapter that is suitable. If I could buy a power cord for the box, I'd give it 5 stars. But as it is, I'm giving it 2 on account that I can't use the thing. At this point, I wish I had gotten something else.

What I've done is I bought: http://www.amazon.com/A200-ST2043-A355D-S6889-A505-S69803-L305D-S5869-L305D-S59222/dp/B0080E6U20/ref=sr_1_77?ie=UTF8&qid=1360113158&sr=8-77&keywords=40v+6a+dc which has DC-Output : 19V-6.3A-120W. That wouldn't be enough to fully power all the ports, but might power half of them... I cut the end off the power adapter and plugged the wires into the terminal block that StarTech provides.

StarTech says that the power light only comes on if the unit is plugged into the computer. The light does not come on if it is only plugged into the power adapter. StarTech confirms this.

This is all plugged in and nothing has blown up yet. There are a couple of interesting SuperUser posts about USB powering:
[...](it won't let me paste links here...)

As for Startech, the person in their chat-support was patient and willing to help, but did not have a viable solution to the problem, and didn't promise anything.

[UPDATE March 5,2013]
Folks, I returned this device (much credit to the seller, Adventurer's Bag for being so helpful!) and instead, I purchased this:
http://www.amazon.com/dp/B009NESU4M/ref=pe_175190_21431760_M3T1_ST1_dp_2
It is a 10-port metal-encased USB 3.0 drive by Orico that does come with a 12v-4amp power adapter.

I don't know if it is a characteristic of USB 3.0 adapters, but with these last two devices (the Startech and the Orico), when you plug a device into a different port, it has to install the drivers again for THAT port. It's not like what you are used to on a computer's USB 2.0 ports where you can plug a device in once and it is always recognized after that. No, with these hubs at least, each port is treated as a separate entity. But after you have plugged the devices into the port, the computer will remember it on THAT port. That means in order for the computer to remember the device on every port, you have to plug it into every port.

Most of the consumer Reviews tell that the "StarTech.com 7-Port Metal Industrial SuperSpeed USB 3.0 Hub Rail Mountable (ST7300USBM)" are high quality item.
