As per the Lenovo specs, there is no powered USB on the T510 at all. For some reason or other it's available only on the T410 and 410s. Similarly, there is no switchable graphics on the T410, only on the T410s.
I knew that going in--I didn't expect a powered USB port, though I wish Lenovo would have included it.
The configurations are not very predictable and features don't necessarily follow price. Buyers would be well advised to check the "Compare" and "Tech Specs" tabs on the Lenovo site before they commit. Of course, they may all not be correct, as shown by the Firewire port on mine... The Firewire was a nice surprise, though; it's not supposed to be here!
[Edit] If I were to guess, perhaps it's an issue with power that is somehow related to the larger screen size of the T510 series?

Erik - Did you try going into standby with a USB peripheral plugged into each of your USB ports? There might be a BIOS setting to handle this, though I'd be surprised if this is disabled by default.
None of your USB ports are yellow/orange?

That's very helpful advice.
I had a dream that I took my laptop apart, and found this:
I didn't find any issues with the seating, nor any cable issues.
There is a small black tab on the upper right, that is a physical extension of the top of the palmrest). It appears to be part of the keyboard support. It's not touching the magnesium underneath, so there's a bit of flex if you push on it. I don't know if it should be seated against metal or not.
I didn't want to unplug the keyboard, as i'm not familar with the connection type. It might be a tiny bit bowed but i wouldn't feel comfortable trying to straighten it.
Then I woke up, and was thankful that I didn't risk my warranty by doing this IRL.
Thanks for the great write up and the youtube video. Hopefully, you'll expand your review to look beyond the keyboard as you spend some more time with the system... I think we'd all be interested in your ongoing thoughts.
In the mean time, let's explore your keyboard observations....
In the past we got a lot of feedback on this, but the focus was always on the left side of the keyboard where there was initially a lot of clear span area, and the reduced weight keyboard, sans stiffener plate from earlier T61 keyboards would tend to flex there. (August 08-Nov 08 builds were the time we heard the most on this). Starting in Nov '08, we shifted manufacturing to use the T61 keyboard while an update / enhancement was developed.
In April '09 and onward, we returned to using the weight reduced keyboard, but added support brackets inside the system to reduce flex / improve the feel on the left side. Very rarely were there any complaints with the right side of the keyboard because there is so much support from the magnesium roll cage there.
Since your system is showing flex on the right side, I have to suspect one of the following things may be a possibility:
1) The keyboard is not properly seated in the system. The rollcage casting (magneslium) has a couple ridges toward the bottom (palm area) of the keyboard tray. When the keyboard is installed it must be pushed down and slid under the bezel below the LCD. If it isn't forward enough, a corner could be resting on this ridge, causing the keyboard to sit high on the right side, and creating the hollow area underneath. Try removing the 5 screws on the bottom with the keyboard icon next to them - remove the palmrest and check the keyboard / reseat it.
2) The keyboard could be slightly bowed. While you have the system apart from my suggestion in #1 above, remove the keyboard (careful with the ribbon cable) and visually check to ensure it is not warped. You can form it slightly with your hand if needed.
3) Lastly, while you have the keyboard out, check the area under it for any wiring that might not be tucked into the appropriate recessed channel in the roll cage. Some of the wires may have paper labels and if one is folded and sticking up, it could prevent the keyboard from seating properly.

You won't void your warranty by removing the keyboard* -- it's considered a "CRU" (Customer Replaceable Unit). The Hardware Maintenance Manual has instructions, and you can watch a video at:
Maybe someone else can comment about the small black tab... it's not ringing a bell in my attic.
Hope you can re-seat your keyboard to get a firmer typing experience.
* Edit: You probably don't have to unplug the ribbon cable, just to re-seat the keyboard. I guess you already found that out.

As per the Lenovo specs, there is no powered USB on the T510 at all.
If this were a true statement, then explain to me why my discrete T510 sitting here on my desk HAS a powered USB port. Mine is located on the rear of the system next to the modem connector.
I also watched the videos regarding the keyboard flex. I can only comment on my system here in that there is no flex on the right-hand portion of the system. On the left side (where the issue resided on T500) I have to apply more force than is required for typing in order to see any flex....and the flex is not significant by any stretch of the imagination. For you to be seeing that level of flex (again, only comparing to a sample of 1 I have seen), I would have to guess that it was not assembled correctly. But I would be very curious to know what you find out when you remove the keyboard.

There's a port in back that IS yellow; I couldn't see it was yellow until just now. The angle is such that you have to look at it from behind to notice, and I had assumed it wasn't there because of the Lenovo site.
Well, count TWO pleasant surprises: first the Firewire, and now the powered USB. If I can fix my keyboard, i'll be all set.

I think I solved the problem.
There are four keyboard screws on the bottom. One is in the middle front, visible at all times. The second one is below the cover for the memory, and cannot be accessed untilyou remove the memory cover.
When i removed the memory cover (which is ostensibly supposed to reveal another keyboard screw) there was... no screw.
That means my KB is being held on by only a single screw, when it's designed to be held by two screws.
