Poll connection in demo seems to error out

[BryanChrisBrown]

Thanks for writing this!

I tried running it but got a panic error,

thread 'main' panicked at 'Failed to poll for events.: Timeout', src\main.rs:14:10
stack backtrace:

Not really sure how to debug this just yet, any ideas for pointers here?

Hello Bryan, can you check the following:

• Is the tracking working with other applications? In the Ultraleap control panel, are you able to see the skeleton hands when putting your hands in front of the device
• Can you try replacing the unwrap by error check, and continue on error? The transient errors happen, maybe it's one that happen at startup
