Error finding FPGA: "okUsbFrontPanel: Could not claim interface" #196

Closed byronprice closed 2 years ago

byronprice commented 6 years ago

I recently merged my branch with the upstream branch and now get the following error:

okUsbFrontPanel: Could not claim interface Device could not be opened. Is one connected?

aacuevas commented 6 years ago

It seems as if it's trying to open the acquisition board twice. Does the issue occur when dragging the Rhythm node to the signal chain or when loading a prior signal chain?

byronprice commented 6 years ago

I've got it set to automatically load a signal chain. I can't get it to open without doing so. Then, it gets stuck with the "Cannot find acquisition board" window.

aacuevas commented 6 years ago

You can always delete or move the lastConfig.xml file, which contains the last loaded signal chain. Actually, please move it and send it to me ( to aaron@open-ephys.org ) so I can see what is causing the issue. I've tried making a chain with an Rhythm node and autoreloading it myself and I cannot seem to reproduce this.
