Hi
I could find a lot of sample codes which are just based on USB device or just USB Host, But I need to connect an USB Flash card to MCU through USB Host and at the same time I need to connect MCU as a device to PC.
With this way I should connect data between Flash card to PC as a Mass storage device by firmware (I don't know OTG can helps me or not?).
For example if you connect this device to PC you can see a removable device which is exactly that Flash card on USB host of MCU.
Besides, my MCU is LPC2478 or LPC2388.
How could I implement such a project?
Thanks in advance
