DualCore_Standalone USB Host Dual Core example
This is a typical example on how to use the STM32F4xx USB OTG Host peripheral to operate with an USB MSC
device connected to the High Speed port and a HID device connected to the Full Speed port.
DualCore_Standalone USB Device Dual Core example
This is a typical example on how to use the STM32F4xx USB OTG Device peripheral, where STM32 is
enumerated as a MSC device in the High Speed mode, and also as a HID device in the Full Speed mode,
using the native PC Host HID/MSC drivers to which the STM324xG-EVAL board is connected.
1、USB HS你要外加USB HS PHY芯片，比如USB3310，没有加的话，就USB HS就不可能成功。
2、还可以用可以用HS的FS 试试的。
