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.
