Reading and Checking the Mainboard ID

Note
  • This tutorial describes how to read and check the ID of a mainboard. For tool boards, please refer to the ID search tutorial for the corresponding product.

Precautions​

Important Notes
  • Must connect to the host computer via SSH, please use network login to connect to the host computer (such as Raspberry Pi and other devices).
  • Before proceeding, ensure the mainboard has been flashed with the USB firmware.
  • This tutorial is only applicable for mainboard ID search, not for tool board ID search.
  • Please confirm the host computer and the mainboard are correctly connected.
  • To view the tool board ID, please refer to the relevant tutorial in the corresponding product directory.

  • No ID Displayed: If no ID is displayed after executing the command, but the lsusb command can detect the device, there may be several possibilities:
  1. System issue.
  2. Incorrect command used; the USB ID search method may not find other firmware.
Handling Multiple IDs

If multiple IDs appear, please select the corresponding ID based on your mainboard's MCU model.
