Gemini Ultraleap service constantly stopping

[EnyoRev]

The LMC was working under the pre-release. Upgraded yesterday to the new version of Gemini and the ultraleap service now crashes constantly. Restarting manually, affects nothing, neither does reinstalling. Log appears as follows for each crash and restart.

Moving back to Orion the device will now show connected and running but there's no data coming in. In the Diagnostic visualizer under Gemini I now get "Data Framerate: 0"

[EnyoRev]

Moved back to the 5.0 preview and now the device keeps disconnecting.

Log follows:

maybe you just need to reinstall the usb driver like in https://forums.leapmotion.com/t/left-hand-misrecognized-as-a-right/15570/4

[dankirby]

Please can you try resetting the firmware by following these instructions and let me know how you get on?

Ran the firmware Reset tool after stopping the leap service

no change

Reinstalled the USB driver.

Current status: Leap Motion shows in device manager, so the system obviously sees it.:

The control panel reports:

Upon plugging in the LMC the Device Status and Calibration Status will briefly flash green and then return to red.

I have the same problem. Hardware shows up in Device Manager under Cameras (Windows 10). The tracking service is in an endless loop, starting and stopping.

I attempted to do the firmware reset but the utility is stuck at "ResourceHost running". Not able to find the location for the drivers, to try that option.

Please help!

[ebrooks50]

An update:

I re-installed the USB driver v. 2.1.0.0 from 2015. This moved the hardware from "Cameras" to "USB Devices" in Windows 10 Device Manager. It has also stopped the endless loop of starting/stopping service.

However, the control panel still doesn't recognize the device as connected.

Appreciate some help. Thank you.

[EnyoRev]

Okay I dropped this for a bit since I was getting a whole new system to put it on anyway.

And on a fresh install, had the exact same problem.

Gemini installed. Same as above. Service constantly stopping.

Downloaded driver from old version. Installed. Leap Motion moves from Camera to USB device as it should.

No change, service still stopping.

Reboot.

Still constantly stopping. can't manually stop from services because it's crashing so often that the system just gets pipe errors:

End task the process tree. Okay. Done.

Using the firmware reset now that I know nothing is running.

Get here. Hit Enter...

10+ minutes later still on that screen.

@dankirby: Please advise?

This is a completely new system with a clean windows 10 install exhibiting the exact same issues. Is this a hardware problem at this point?

[ebrooks50]

I have to say the response and support here is incredible.

Thanks @dankirby for ignoring this thread.

[dankirby]

Hi, my apologies for the lack of updates here.

We have been working hard on an update to Gemini V5 which addresses these reported issues which should be avialable soon to test with.

I will post a further update here as soon as it is available.

[yzhu04]

I have the same problem with you! Yesterday I just bought a second-hand leap motion, and download Gemini to use that. It works well in first 2 hours and then I download the newest version of Gemini, and I try to recalibrate it. And everything goes wrong after recalibration. It always shows stop running, and cannot recallibration!

[yzhu04]

I think it's totally firmware's problem, after I download the newest version's Gemini, it just die without any reason!!!
Plz give us a solution because it's super fatal problem and makes me feel that I bought a leap motion for no use except telling me it's not working.

[EnyoRev]

Waiting with interest then.

[dankirby]

Thank you for your patience and my apologies for any inconvenience caused by these issues.

This morning we have released an update to our Gemini V5 tracking software which includes fixes for a number of reported issues.

Please can you uninstall the Gemini V5 software and download and install this 5.3 release from here and let me know if this works correctly for you?

If any issues persist please can you forward the new tracker log to support@ultraleap.com along with the specification of your PC that this is being used with?

The tracker log can be found at the following location on your PC:

C:\ProgramData\Ultraleap\HandTracker\Logs\tracker_log

[EnyoRev]

At this point I'm just assuming that firmware update that multiple people, including me, reported as frozen damaged something. Here you go though.

Clean Install
Leap Motion installed as a camera (guessing that's by your choice since you'd include the driver you want in a new installer, right?)

Service is no longer crashing constantly

Here's my basic specs but honestly everything was working in the pre-release version of Gemini, updated to release gemini and nothing has worked since even when trying to roll back and across two completely different computer system. This has been a solid month where part of my standard workflow has been completely inoperable.

[ebrooks50]

Please can you uninstall the Gemini V5 software and download and install this 5.3 release from here and let me know if this works correctly for you?

I have only removed the app during the un-install. The package updated the device in the Device Manager on its own (it's now a Camera again) and installed a redistributable.

Everything seems now to be working properly. Thank you!
