Hello everybody ! I have a big problem: I have a mbed LPC11U24 and yesterday I updated my device with the latest driver (version 141212 ) and followed the explanations by "Power-cycle" the board. And now my Mbed isn't recognized itself by windows. it appears at an Unknown Device and "The device driver could not be installed". I have tried to install it manually by downloading an other firmware but I had a message saying that "The driver is up to date". So please What can I Do to restore the original firmware on my Mbed ? Do you have any idea in order to fix it ? I pushed on "reset" button on my Mbed but the led goes out. Even by pushing it a few seconds, it doesn't change anything. I precise that before I updated the latest firmware, the mbed worked fine.

PS: I hope you will understand my message, My English isn't perfect.

I have found how to fix it ! In fact I had to press and hold down the reset button and connect the USB. I didn't do that in that sequence !
