USB is host contolled bus. This means that there might only one unit with contoll capabilities (Host) and many others responding to it's request (Device). They aren't so different but still incompatible. It's not only a question of stack. There is also difference in power control, addressing and presence of pull-up resistors.
STM32F103 has only Device capabilities and CAN NOT BE USED WITH ANOTHER DEVICE on the SAME BUS. STM32F107 has OTG (On-the-Go USB) wich allows it to act as Host if you use a proper cable.
So far i think conncting primer2 to webcam is impossible.
