Windows 7: Error ID 2001 - Usbperf - each time I launch perfmon.exe

30 May 2012   #1

Windows 7 Ultimate x64 - SP1
Error ID 2001 - Usbperf - each time I launch perfmon.exe

Hi all

Since a couple of month I get an error log message when I launch permon.exe :

Error ID 2001 - Source : Usbperf

Source: UsbperfType: WarningDescription:
Unable to read the "First Counter" value under the usbperf\Performance Key. Status codes returned in data.

Microsoft has published a workaround but it doesn't work on my system :

usbperf Event 2004 is logged in Application log

I have searched many sites onto this subject but all my research led me to nowhere ...

Does someone has a idea to get rid off these annoying message ?

Thank you

The workaround disables that check - so the errors should not be seen in the event log.
I suggest checking the workaround to see if the registry entry exists as it is suggested in the article:


 3.  On the Edit menu, click Add Value, and then add the following registry value: 

 Value name: Disable Performance Counters 
Data type: REG_DWORD 
Radix: Decimal 
Value data: 1

Thank you for your answer.

Unfortunately, I've already tried set this key in different places.

No changes, except an error message when I try to lauch perfmon.exe (no remember exactly but it's like : unable to set this counter).

Check Windows for corruption. Run SFC /SCANNOW Command - System File Checker up to three times to fix all errors with a restart in between each. Post back if it continues to show errors after a fourth run or if the first run comes back with no integrity violations. Use OPTION THREE of SFC /SCANNOW Command - System File Checker to provide us with the sfcdetails.txt file if errors occur.

After the 1st scannow all errors were fixed. I have rebooted and scanned again 4 times without any more error detected.

Error message still present in log after lauching perfmon.exe but this sfc/ scannow cleaning had to be done

Is there an easy way to update usbperf.dll, could it be useful ?

If you'd like to try replacing it, here's a copy from my system (attached to this post in a .zip file). My system is also Win7 SP1 x64 bit

As with any unknown file from the internet, scan it with an antivirus BEFORE opening it.

Good luck!

Well, thx for the file but mine is protected by the system when I try to replace it

It's probably not corrupted anyway (because of the protection on it).
