Program gets "Error Setting up PI Engineering Device", crashes if I do anything after that.

[rec]

I built as per the instructions without incident, and attempted to run the demo program build/testgui/pietestgui. I see a GUI window, but when I click start, I get:

`Error Setting up PI Engineering Device`

and then the program crashes if I try to actually do anything.

I instrumented the program a little and discovered that the error code (which the programmer didn't take the time to put in the error message) is 205: PIE_HID_SETUP_CANNOT_OPEN_READ_HANDLE and the path that it's trying to open at that point is 0003:0010:00 (whatever that means).

Here's what's printed on the console.

Can confirm, seeing the same issue.

Hello, jgarvin. Because this problem does not exist across the board (did not/does not exist on our test machines), we need a bit more information to chase down the issue. Which distro are you seeing this behavior on?

[jgarvin]

I actually figured it out. The problem is just that I hadn't copy the udev file over, so my username didn't permission to access the file for the pedals. You might want to add a FAQ entry to your README or change the program itself to suggest checking this in the error message.

While I have your attention though -- is there anyway using the bundled programs in the SDK to map the pedals to key presses, or do I need to write code myself using the API to accomplish that? (I'm on Linux)

jgarvin, thank you for the follow-up. It sounded like a permissions issue to me too, but I wasn't sure the culprit. I will add it to the list of updates.

The SDK doesn't included any sample code for key presses, but when I was testing originally I used this sample as a reference to send keystrokes: http://www.doctort.org/adam/nerd-notes/x11-fake-keypress-event.html
