This type of issue depend on timings: packet sizes and board DMA performance. Anyway, could you please elaborate: 1. 960 bytes case. Is it high bandwidth transfer? I mean how many packets sending in 1 (u)frame? 2. Could you please print hsotg->frame_number in function dwc2_gadget_handle_out_token_ep_disabled(). 3. No any chance to record USB trace?
