[PATCH v3 16/17] usb: dwc2: gadget: Program ep0_mps for LS

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Vardan Mikayelyan <mvardan@xxxxxxxxxxxx>

When device is enumerated in LS we should program ep0_mps accordingly.
USB2 spec says that in LS mode, control ep mps must be 8.
