I’m trying to disable/enable USB camera using devcon. It fails with the following output:
c:tempdevcon>devcon disable “USBVID_199E*”
USBVID_199E&PID_8207&MI_008&11CAF5B4&0&0000 : Disable failed USBVID_199E&PID_820716210163 : Disable failed
I execute devcon in a console run with admin privilegs
What could be the reason?
I have such issue when tried 32-bit devcon.exe (located in Program Files(x86)) on 64bit Windows 7.
Solution is to use 64-bit version of devcon.exe
Also, you need to run devcon with admin privileges (ie, start cmd as Administrator, then run devcon).
