COM port disappeared for mbed on new HP Spectre 360 computer
/media/uploads/captaintim/com_port_issue_with_hp_spectre_360.doc Just bought a new HP Spectre 360 with fast 256GB SSD storage and discovered my mbed has been demoted to a portable device (no more COM port for you, see screen shot). Some other controllers (nRF51 DK, BC118) I use worked when I download FTDI drivers but mbed remains unaffected. Anyone else have this problem? One workaround suggested connecting using a USB>UART cable but no RS232 jacks are available on this machine.

The Lpc1768 module will show up automatically as memory stick, but you have to install a device driver for the serial port. Check the platform page for the link. The USB to Uart cable can connect between a USB port on the PC and a serial port (3v3) on the lpc1768 side using one of its serial ports. This could be an FTDI like device that also needs a driver on the PC side.
Thanks for your suggestion to install a serial port driver. I think I was fooled by it appearing as a serial port in Connected Devices. Here's where the driver and explanation is located: https://developer.mbed.org/handbook/Windows-serial-configuration I clicked on the download and saved "mbedWinSerial_16466.exe" ran installed the driver I needed. TeraTerm when started displayed text and numbers when connected to the Hewlett Packard Spectre 360 computer which it wasn't doing previously. Nice job and thanks for the help.
