Description Uwe Hermann 2015-07-31 21:53:32 CEST

The saleae-logic16 driver doesn't work as expected if channel 0 is not enabled/used.

Happens with both sigrok-cli and PulseView, so it's likely a libsigrok or hardware issue.

Example when only channel 0 is enabled (works correctly):

Example when only channel 3 is enabled (doesn't work as expected, i.e. it doesn't return 10 samples, and says "status LIBUSB_TRANSFER_TIMED_OUT received 0 bytes" instead):

This works for me with the MCUpro version.
