LS1046A RDB not booting: mbed problem?

I've just setup my LS1046A RDB kit and followed the Getting Started Guide:

Downloaded and installed the mbed serial port driver and installed Tera Term,

When connecting the USB cable between console port and PC, Windows shows an USB drive/folder for a short period, and then is disappears. This continues on and on. The green LED D8 periodically blinks (like the CMSIS-DAP controller is rebooting).

Sometimes it becomes stable, and the USB folder contains a file fail.txt with content: SWD ERROR.

 

Any suggestions (We have 2 kits with the same problem)?
