Leap Motion (critical scorce exception: unable to enumerate

PaultheGreat 2014-03-29 02:33:33 UTC #1

So I'm tryin' to leap motion, and notice it's not connecting.

it won't let me resume tracking. I try reinstalling it a few times, reboots and different ports, no luck.

Green light is on, red lights are off.

[21:25:31] [Info] Tracking resumed
[21:25:31] [Info] Tracking paused
[21:25:40] [Critical] Scorch exception: Unable to enumerate a device with the specified name

That's what it says in the software log.

In my device manager it says "leap dev kit" and has a /!\ warning icon on it.

Says

Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)

I tried lots of stuff, but no progress.
Extra clues: two generic webcams using usbvideo.inf drivers also stopped working, but I got 'em re-enabled by installing specific drivers for them.

Maybe it's a problem with USBVIDEO but I cannot find any proper info now that yahoo search was replaced by bing

Hi PaultheGreat,

We are sorry to hear that you are having a problem with the set-up. Once the driver is installed, it should appear as “Leap Motion Controller” under Universal Serial Bus Controllers.

Please try the USBVIDEO fix from this thread: https://forums.leapmotion.com/forum/support/community-support/windows-os/2876-device-not-detected-fix?3033-Device-Not-Detected-Fix=

Go to the Device Manager.
Click on the Leap Motion device, and select “Update driver”.
Click "Browse my computer for driver software"
Click "Let me pick from a list of device drivers on my computer".
Uncheck the "Show compatible hardware" checkbox.
Select "Microsoft" as the manufacturer.
Install the Driver for the "USB Video Device" model.
Unplug and replug your Leap Motion Controller.

Those instructions posted by @LM_Kevin were for our old (DirectShow-based) driver model. Occasionally there would be a red exclamation mark next to "Leap Dev Kit". Sometimes using "Update Driver" would fix it, but are some cases where this is unfixable.

Either way, it's preferred that you install the newer WinUSB.inf based driver that should be labeled as "Leap Motion Controller" under Universal Serial Bus devices. Are you already running version 1.1.3 (the driver was introduced in 1.1.0)? Sometimes this can be fixed by reinstalling the software. If not, you can find the driver under C:\Program Files (x86)\Leap Motion\Core Services\Drivers and try installing that manually. After installing, be sure to unplug and reconnect your device on the USB port and check Device Manager again.

If you cannot install the driver our software falls back to DirectShow, but that leaves you vulnerable problems like the red exclamation mark and some programs treating your Leap device as a webcam.

So I ran dpinst64.exe

and that installed the driver for the leap.

And installed it as the leap's driver.

I was in the 1.1.3 driver version.

When it was installed as a camera, it didn't let me install the driver from the leap folder - I had to use dpinst64.exe

Thanks for the help!! I can now make leap music in peace.

I was tearing my hair out trying to get it to work.

Yup, running dpinst64.exe in C > Program Files > Leap Motion > Core Services > Drivers instantly did the trick.

hi i have a similar problem as PaultheGreat wich is the closest i have found however my leap motion unit has a red light on it and i am using different software version. shows up as leap dev kit in device manager under the webcam icon and i have installed and uninstalled multiple times recent Windows Version 5.6.1 and old versions. might be a simple error from me but most likely not. i believe i would need drivers of some sort that are still available. if anyone can still reply thanks!

Did you try running C:\Program Files (x86)\Leap Motion\Core Services\Drivers dpinst64.exe or dpinst.exe?
