Unhandled exception: Failed to set Hardware property 'Sharpness' as a part of DeviceWrite

[_jts]

Hi there,

Just got my Leap Motion controller from Amazon and am trying to use in Manjaro Linux (kernel version 4.15.18-1 if it matters). I installed the 2 available packages, leap-motion-driver & leap-motion-sdk, from AUR. Running lsusb shows the device as "Leap Motion Controller". When I try to run sudo leapd though, I get the following over and over again:

[Info] WebSocket server started
[Critical] Secure WebSocket server failed to start

[Info] Leap Motion Controller detected: LPXXXXXXXXXXX

Would appreciate any help getting this resolved. I saw other threads that mention this error, but the package suggested to reinstall was a .deb file, not a .pkg.tar.xz file. I tried downloading and converting the .deb to a .pkg.tar.xz using debtap, but was getting errors.

same error here unfortunately.

I've escalated this to our engineering team to investigate

I am getting the exact same error as the poster above. I tried to use the leap motion on my macbook pro 15" 2018 and my friends macbook pro 13" 2015. When the leap motion is plugged in, its LED on the side turns red. Any help would be greatly appreciated.

[jhung]

A red LED usually means an issue with the firmware on the device. Are you seeing the same sharpness error in the software log as the original poster?

If you're not, you can try resetting the firmware by running our firmware reset tool:
https://leapmotion.box.com/s/x0por7h9ypltc2rtr5ez

Mount the .dmg file and open up a Terminal window and input the following lines:
cd /Volumes/LM_FirmwareReset_Mac
./FirmwareReset

[jgalvin97]

Hi thanks for the response. We downloaded the dmg and followed your steps. The firmware reset tool ran asked us to pause tracking, we did then it asked us to "please plug in your leap motion controller.". Yes we have the sharpness message in our log, our log is identical to the one above.

[jhung]

Try uninstalling the Leap Motion software and install the version here: https://leapmotion.box.com/s/fyh1nxdwvmslg2f18qep1e1r5xx05p38

Unfortunately, we don't have a version of this installer for Linux at the moment and the Windows version is a bit outdated.

[jgalvin97]

I've just uninstalled and installed your software version but I still get an error relating to sharpness. Here is the software log.

Thanks for the info. I'll need to have our engineers look into this. I've already escalated this issue to them and will update when I have more information.

[spencercap]

i tried the firmware reset tool also, but no luck.

i was able to get around this issue only by updating the leap motion device using the leap motion software on windows 10 via bootcamp on my macbook pro.

[jhung]

So the firmware update on Windows resolved this issue for you?

Mac OS 10.12.6
Leap Motion v2.3.1+31549

I'm getting the same issue. Device light is red as soon as I plug it in to my laptop. Software log shows this below repeating over and over again. This is the second controller I've had that has been relatively DOA. The MacOS Firmware Reset Tool was a damaged file in the dropbox link on the website, so no go there. Ordered a new one (this current one) and am still experiencing similar issues.

UPDATE
It just displayed the below and now is not being recognized by the computer at all. There is no light on the device LED there is no recognition from the Leap Motion software. There is a WestBridge device shown as connected in the system information pane.

The MacOS Firmware Reset Tool was a damaged file in the dropbox link on the website, so no go there.

You need to open up a Terminal window and manually run the reset tool by entering the following lines:
cd /Volumes/LM_FirmwareReset_Mac
./FirmwareReset

Let me know if that revives the controllers for you

Same issue on Mint 18.3. Solution was to have a friend with a windows machine reset the firmware. Now it is functional, but it doesn't work nearly as well as it did when we tested it on the windows machine. Is this because the windows drivers are of the Orion version, while the linux driver/daemon is based on v2.3.1 SDK? If not, are there any provided tools to find problems/bottlenecks? Do I need some specific udev rules or anything? I followed the instructions in the README but it provides no further insight into the performance differential. It is honestly barely useable.

[jhung]

Is this because the windows drivers are of the Orion version, while the linux driver/daemon is based on v2.3.1 SDK?

This is correct. The v2 software was released a few years ago whereas the latest version of the Orion software (v4) was released a few weeks ago. The hand tracking has much improved since the release of the V2 software.

I'm also getting this issue now.
The log below repeats over and over.
LED on the device is solid red.
Macbook Pro running 10.13.6
I have tried the firmware reset software using both mac and PC.
On Mac the software hangs at 'Please plug in your device', and on PC it hangs on the prompt following.
Have uninstalled and reinstalled Leap software and restarted my laptop a number of times. Same issue on another mac.

Any workarounds yet?

Unfortunately, it sounds like there's an issue with your controller. Where and when did you purchase it from?

[rjpeart]

It's ok, we got it sorted using the firmware reset module on another PC.
