Running codes of mbed USBHID in my own board

Hello I want to use mbed codes for USBHID in my own hardware (nxp lpc1768). I read what is in the link of prototype-to-hardware, and I used jtag for programming of my own micro (my board also accept .bin for programming). When I use mbed board, computer recognizes the incoming usb and I can communicate with the board via usb, but when I use my own board, the computer returns an error indicating that the incoming usb is not recognized (it is good that computer recognizes that it is a usb, but computer cannot find appropriate driver for it). What is the problem? Do I need to develop some drivers ? Thank you.

Do you have it wired correctly? For example here is how the application board did it: http://developer.mbed.org/cookbook/mbed-application-board#schematics

yes I do it correctly, just as what mentioned in the web site of prototype-to-hardware. but, when I want to get signature of device or start the application using Flash Magic, the bellow error returns: Operation Failed, failed to autobaud - step 1

Thats a completely different error than the one you mentioned above. Which USB -> Serial converter are you using to run flashmagic?
