Hi,
we want to use the STM32F106RCT6 in our Future Products. So we Build an prototype an all works fine except the USB DFU Bootloader. We plugged the USB Cable in and the PC didnt recognize the Device.

The Markings on the Chip

STM32F107
RCT6
990RG    93
MYS  99  031

We wired the Vbus on PA9, an rest of USB also, BOOT0 = 1,BOOT1=0

After the Reset nothing :O

Whats wrong with these Chips? Have we forgot something?
