I am trying to transmit and receive data on a STM32F7 (USB HOST CDC). After I receive and transmit bytes a few times my IN pipe shows a URB_Status of USBH_URB_NOTREADY and never reaches a USBH_URB_DONE state.

I am trying to transmit and receive data on a STM32F7 (USB HOST CDC). After I receive and transmit bytes a few times my IN pipe shows a URB_Status of USBH_URB_NOTREADY and never reaches a USBH_URB_DONE state.

Any ideas as to why this might be happening?

I am referring to the usbh_cdc.c file generated by CubeMX.

Thanks
