Sorry for delay. I haven't enough time to investigate deeper.
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?
Thanks,
Minas
