Receiving data over STM32F407 or STM32L476's USB OTG using DMA?

[Viki]

Hello!

I am working on a project and I need to receive data over USB OTG using DMA, but I could not find any channel link to it. I have configured DMA but I don't know which channel to link with it ( __HAL_LINKDMA(__HANDLE__, __PPP_DMA_FIELD__, __DMA_HANDLE__), somebody help me please....

Thank you for the response. I am using STM32F4 Discovery and STM32L476RG Nucleo, USB CDC on both. I want to receive data from PC over CDC using DMA but I could not find any resources.
