I have built the moufiltr sample, installed on several OS. I found the re-entrant issue on Windows 8.1 platform if the USB device is USB 1.0, which is USB low speed device. The same driver can work on Windows 7 x32/x64 or USB 1.1 devices on Windows 8.1 x32/x64. I don't know why the moufiltr driver has the limitation on such the specific combination, USB low speed mouse + Windows 8.1. Could it be something I had missed?

Any suggestions would be greatly appreciated.

Thanks!

  • The fact that FilterEvtDeviceAdd is called twice doesn't necessarily indicate that anything is wrong. What is the actual problem? – Harry Johnston Oct 16 '14 at 20:18
  • It will block functionality of mouse. I am curious about what the windows kernel did on windows 8.1 only. – Stanley Li Oct 17 '14 at 01:03
