I totally understood what the original poster is getting at.  I believe the  
word to describe controller lag would be "latency".  A quick google will  
send you to numerous programs that will allow you to basically overclock  
your usb ports to a faster pooling rate and/or latency. HOWEVER,
  According to "The USB Man",   
(http://www.usbman.com/Guides/VIA%20Tips%20and%20Tricks.html), USB's don't  
overclock well and before mentioned programs usually result in even lower  
performance results. Instead He points the finger at the motherboard  
chipsets, ( VIA in particular ), and offers a plethora of solutions ranging  
from chipset latency patches, to updated controller drivers, to simple  
motherboard Bios settings that can enhance your usb latency and get your  
controllers lag free.
  And when all else fails he offers a sure fire way to beat usb lag by  
simply buying one of his reccomended brand PCI cards that converts to usb  
jacks, cutting out the chipest flaws all together.
  I highly reccomend anyone feeling the controller lag crunch to read this  
page. I think it's safe to say that what we are talking about here is not a  
fofix/python problem, and instead a "latency" issue that copious amounts of  
PC owners experience on a regular basis only due to few bios settings or  
lack of a better chipset driver.

I would also like to add some info that pertains directly to us that is  
good to know and may also help fix some controller lag issues.   I have  
used logitech bluetooth mouse and keyboard combo's for quite a few years  
now. There has been countless times wherethe mouse was basically unuseable  
due to lag and/or jitters. After much research I learned that bluetooth is  
on the 2.4 ghz frequency, along with cordless phones, wi-fi A-G and earlier  
revisions wireless-n, and of course my Wii strat, and other guitars.  
Allthough the wiimotes are bluetooth, the guitar usb dongles are 2.4 ghz,  
and I would imagine the same goes for PS3 guitars and xbox guitars as well.  
With all this crap on the same channel it doesn't take much to flood it to  
where devices are taking turns waiting in line for some bandwidth.
  I have verified this to be 100% the true cause of my bluetooth mice going  
haywire sometimes.
  I tested the theory by transferring large files from my laptop  
(wireless-n) to my home system through my wireless-n router. During large  
wi-fi transfers my bluetooth mice are all but useless. So if your  
controller lag is sporadic and offbeat, maybe check the roomates laptops  
for heavy wi-fi usage IE torrents, or limewire.  Just another possibility  
for those occasional moments when you're missing notes that you know you're  
hitting them dead on. We've all had them!

Again,  The link to the USB Man's solutions is

Good Luck!  I hope this helps!  =)
