I assume you really mean USB HID (Human Interface Device) and 
sub-standards that work with keyboards.  USB is fully able to manage 
arbitrary data.

... Now... I went looking for reviews... and got mixed results... saying 
the G510s has 6 or more than 6 rollover.  It would appear that Logitech 
uses drivers that kick in for alternate personalities of the keyboard 
(including the use of the macro keys and the display).  It may very well 
be that as a "pckeyboard" USB devices, it has 6 rollover and as a 
logitech driver keyboard, it has other statistics.

There was one Logitech I found, tho, that claims 26 rollover... so 
there-you-go.

Either way, my real point was that I've found that the macro keys are a 
big deal ... after adequate rollover ... which I'd put at about 4.
