The TG-LPC11U35-501does not have mbed interface chip on board and USB port connects to target chip USB pins. Therefore, Windows device manager may require USB driver depending on your program in the flash memory. e.g. If you programmed code which use USBSerial for printf/scanf, you need to install USBSerial driver here. https://developer.mbed.org/handbook/USBSerial

But, if you programmed just a simple blinky program for instance, you do not need USB driver and Window device manager shows "A driver isn't installed", which is expected behavior.

Thank you for your help. I programmed code which use USBSerial for printf. When the driver you told was used, USB could be recognized now. I really owe you a lot,

You will see TG-LPC11U35-501 as USB mass storage. When you connect the TG-LPC11U35-501 to Windows PC at first time, Windows build-in driver will be installed automatically. If you have a driver problem, you can update with device manager. There is no specific driver.
