5.14 Serial list empty

Typical symptoms

  • OS Device Manager sees a COM/tty entry but Studio’s picker is blank.
  • “Authorize serial first.”
  • Open fails → port busy.

Why it happens

Local serial tooling needs explicit pairing. Hit Add, pick your adapter in the OS dialog, then the Studio dropdown fills in.

Fix flow

  1. Verify Windows/macOS/Linux enumerates the cable; install FTDI/CP210x drivers when missing.
  2. On terminal or serial add-flow press Add.
  3. Confirm the debugger’s COM/tty inside the consent UI.
  4. Choose baud (115200 typical) and Connect.
  5. If everything shows “Unknown,” purge via Clear unknown serials, then redo authorization.

Remember: serial view doesn’t create a persisted device—you still need SSH for Moss tooling, filesystem, RD, OpenClaw, etc., once connectivity returns.
