Devcon unable to reset a device RRS feed

  • Question

  • Hi Team,

    I am facing an issue i connect USB camera to my remote system after some days my USB camera goes down due to power disconnection automatically and even not shows in device manager.  I saved its HW instance ID and tried to reset the device to initiate USB but it gives error that device not present. Camera start working if i physically plug unplug camera USB how can i reset device without physical visit to re initiate USB device.

    I am facing great trouble in that its also impacting me financially appreciate your quick response.

  • If the device is missing from device manager, it has been reported missing and nothing relying on pnp can manipulate the state of the camera. This includes devcon. Your only hope is that the UsbView application shows some indication of the device and you can do something to the parent upstream usb hub to trigger the device to reenumerate properly
