I am running Windows 7 on a Thinkpad W510 and just bought a Logitech S520 wireless keyboard and mouse.
When I try to boot, the system hangs at the Thinkpad splash screen.
I updated the BIOS to the latest version but it had no effect. I also changed the boot sequence so that USB boot was after HD boot.
This had no effect and the system still hangs on boot.
If I remove the USB receiver the system boots fine and I can then insert the USB receiver and everything works propely.
Is there anything that I am missing? This just doesn't make sense.
Thanks for any further suggestions.

don't use usb 3.0 port.
it should work fine in other 2 usb 2.0 port.
at least in my W510, usb 2.0 port work fine with logitech's receiver.

My w510 hangs with pretty much anything plugged into the USB on boot.
My guess is it'll take a BIOS/Driver update, but no word yet on when.
Call lenovo support and raise the issue so they have more datapoints of it happening.

I have the newer port replicator (issued July ?? 2010) and it is always plugged in to USB 2 port. From the port replicator I go to a powered USB hub. In the later I have the transmitter for my Logitech mouse. I have never tried the Logitech transmitter directly in my laptop so can indicate whether that would hang my system and at least right now I'm not interesting in trying it.
