# Version 0.53.1

> October 6, 2026

## <u>Bug Fixes</u>

* **`lager instruments` did not list a J-Link with an unlisted USB product ID.** The Lager Box
  knew only five SEGGER product IDs, so it skipped other probes. An example is the on-board
  J-Link OB of a development kit. `lager nets tui` and `lager nets add` did not offer the probe
  either. The box now lists every USB device with vendor ID `0x1366` as a `debug` instrument. A
  probe of a known model shows its model name, for example `J-Link_OB_2VCOM` for product ID
  `1051`. Any other probe shows as `J-Link`, and its address keeps the real product ID. The fix
  is in the Lager Box code, so run `lager update` on each box to get it.

## <u>Known Limitations</u>

* **An on-board J-Link OB does not offer its serial ports as `uart` channels.** Its
  `/dev/ttyACM*` ports do not appear in `lager instruments`.

## <u>Installation</u>

```bash theme={null}
