mbed LPC1768, no reaction when connecting to USB

09 Apr 2018

Hello, I tried to connect the mbed 1768 to the USB of two PCs (1x WinVista, 1x Win10) , but there is no reaction, this means I cannot see the mbed as a storage drive. On this PCs there are several software and drivers for electronic development (i.e. Atmel Studio, Jungo driver for AVR mkII, and more) installed. When I connect the mbed to a real office PC (only win7 and office installed) I can see the mbed in the device list and I can use it as described in the manual. So my question: what can bloc the mbed at my two development PCs ? Do you have any ideas? Thank you
