At this point sigrok-cli says there is an error and stalls (I can't kill
it with control C, the main thread is gone but there are worker threads
still running).
Here I unplug the device:
{{{
KERN: usb hub 7: KERN: port 2: device removed
KERN: usb xhci 1: cancel queued transfers for pipe 0xf5719c38 (0)
KERN: usb hub 7: port 2: new device connected

And a little later:
