Hi,

Could somebody tell me where may I find some information about range of addresses of endpoints? In reference manual for stm32f4 I find out that there are ontly 3 in/out endpoints.

In example application IN endpoint has address 0x81 but OUT 0x01, how to count that value?

Thanks in advance :)

You can find the information about the endpoint address bits on the usb specifications. The endpoint address is defined by the usb standard, not by the microcontroller.
