1. Short description.
  This driver/program is intended to "overclock" USB mice under Windows 98
  through XP x64. I have personally tested it only under Windows 98SE,
  Windows 2000 SP2 and Windows XP SP1. Testing under Windows XP x64
  was performed by Dark_Cloud.

  You can learn more about theory and the program here:
  http://www.overclockers.ru/lab/15925.shtml (in Russian language(*))

2. Installation:
  1. !!! See addition from 2005/12/26 (on text below). !!!
  You need a patched version of the system driver USBPORT.SYS for
  versions Windows 2000 SP4, Windows XP and Windows XP  x64. 
  You DO NOT need to perform the same action for Windows 9X, ME and
  2000 till SP2. There are comments that you also do not need to patch 
  USBPORT.SYS under Windows 2000 SP4, but I did not check it.

  First, make a BACKUP copy of USBPORT.SYS(*)

  Locate the patched USBPORT.SYS in the corresponding folder 
  USBPORT_Patched\*\ You have to install it by overwriting 
  the current one in the following order (for 32-bit OS):
  %sytemroot%\Driver Cache\i386\
  %sytemroot%\system32\dllcache\
  %sytemroot%\system32\drivers\  

  Use the following order for 64-bit OS (I did not verify it):
  %sytemroot%\Driver Cache\amd64\
  %sytemroot%\system32\dllcache\
  %sytemroot%\system32\drivers\

  After that reboot. After rebooting check, if USBPORT.SYS in             
  %sytemroot%\system32\drivers\ is the one patched by me. You can do that
  for example with FC /b

2. Install my driver HIDUSBF.SYS. For this purpose execute SETUP.EXE (there
  should also be .INF and .SYS files). Click Install Service. 
  Then choose the line with your mouse and put a checkmark Filter On Device.
  Check that in the row Filter it says Yes.After that choose desired refresh
  rate. After that click Restart. Check if the refresh rate has really 
  changed (for example with the program Mouse Rate Checker). 
  If your rate did not change, then you should either  restart, plug out
  and plug in mouse cable or stop your mouse and restart it in 
  Device Manager. Dark_Cloud has reported that the button Restart does not
  work in Setup.EXE under XP x64. I cannot possibly look into it at the moment,
  since I don't have that hardware and software. If the rate does not 
  increase more than 125Hz, then you should try DECREASE it to 31Hz or 62Hz.
  If the rate does decrease, then the driver functions properly, but 
  you didn't complet Step 1. - the patched USBPORT.SYS was not installed.

  Good luck in overclocking mice :)

1. Translation was executed into English.
Job was done by TimFortress (email: mofey@front.ru) 2005/07/22
(*) in text above is translator additions.

2. In case of HIDUSBF service wasn't installed under Win x64 through Setup.EXE
(button "Install Service") you may try to do this by OS standard possibility:
mouse right button click on HIDUSBF.INF -> Install

3. There was added possibility to uninstall HIDUSBF service and file:
mouse right button click on HIDUSBFU.INF -> Install

Added 2005/12/26:

1. Driver was enhanced - for its installation under XP is NOT 
required to install corrected USBPORT.SYS. However, if there is observed
some anomalies - you may go back to old working sequence
(corrected USBPORT.SYS + driver in the folder DRIVER\STD).
Thank Alan 'Strider' Kivlin for the idea of patching the code 
of USBPORT.SYS on the fly.
Thank Root for valuable link for realization.
The same development for Windows XP x64 is still not done - there is a
difficulties with testing.

--------------------------------------------------------------------------------

Added 2006/01/12:

1. Above-mentioned development is executed for XP x64.
Thank Dark_Cloud once again for recurrent testing.

--------------------------------------------------------------------------------

Added 2006/09/30:

1. Drivers for 98/ME and 2000 shrink to fit in one page.
2. DRIVER folder and HIDUSBF.INF reordered.
