When I run the Virtual Com Port demo and connect the Keil board to the PC, Windows installs an ''unknown USB device'' which has the following device instance ID:
USB\VID_0000&PID_0000\5&1B4CAF5C&0&2 Can anyone suggest what I need to change to get this demo to work? Thanks. [ This message was edited by: emann on 01-04-2008 18:57 ]Options

emann,
Check how far the stm32 gets using a debugger. If you find where it gets stuck then that may give some clue. Also, the MCBSTM32 has a different line (PD2) to disconnect the USB, so check that that port is configured okay or tied to ground using the jumper if it isn't used in the example (i.e. not floating). Paul.
