Troubleshooting

If the adapter is unavailable, check the platform capability message first. Missing usbmon access or missing USBPcap are environment issues, not packet parser failures.

If the timeline is empty, confirm that the selected device is actually producing traffic and that endpoint, direction, type, text, or hex filters are not excluding every row.

If a saved case looks incomplete, reopen the .bscope session and inspect whether payload retention or platform capture permissions limited the evidence.
