If multiple executions of colctl are done in a short amount of time this error is shown:

$ colctl --status
Device status:

Most probably the USB devices is not reset before

Please also consider Windows support. It is broken now. I will fix this tomorrow.

Sorry about Windows, I have not thought it could break it.

@leinardi No worries, glad you are helping. For once I directly pushed the fix because I guess it is not worth a review.
