My mbed is NOT recognized by my PC

Mbed OS

My mbed is not recognized as a port by my PC. Instead, it is recognized as a portable device. I want to do serial communication with Tera Term. I know win10 doesn’t require serial driver installation. Please someone solve this problem.

Hello Jan

・My PC OS : Windows 10 Home
・My mbed : LPC1768
・My using teminal : Teraterm
・What i already tried :
(1) I can compile from pc to LPC1768 and run some program
(2) I wanted serial communication to get the value of the 9-axis sensor with mbed
(3) But my Teraterm does not recognize my mbed
(4) After investigating, I found that win10 does not require the mbed usb driver
(5) But device manager shows my mbed as portable device

Please let me know if you find out…

  • Connect the USB cable directly to USB port of your motherboard, not to a front panel.
  • There were an issue on WIn10 I think, so if you have still old firmware… this could be also handy - Firmware LPC1768 LPC11U24 - Handbook | Mbed
  • Check if some device was not recognized via Windows device manager

If steps above does not help and you have a laptop with Win10 Pro, then connect the usb cable to the laptop. I’ve never worked with the Win 10 Home, but I remember from older Windows versions, that was always pain to work with Home edition when you want to do something more. You will see if something change.
