I had a deeper look into the PCD HAL code to verify this issue. It turns out that in stm32f1xx_ll_usb.c the maximum receive packet size gets correctly set in USB_ActivateEndpoint() but not in USB_EPStartXfer(). Here the requested length from HAL_PCD_...

I am having the same issue with STM32F103C8T6. The device descriptor request is received, the device address gets set and after that I receive a SETUP with "80 06 00 01 00 00 12 00" for my just assigned address which triggers the setup interrupt rout...
