Dear Troy Kisky,

> set wMaxPacketSize for full speed descriptors
> fs_source_desc, fs_sink_desc to 64.
>
> Full-speed bulk endpoint can have a maximum packet size of
> 8, 16, 32, or 64 bytes, so choice 64.
>
> The hs_source_desc, hs_sink_desc, already have their wMaxPacketSize
> set to 512. That is the only legal value for high speed bulk endpoints.
>
> Strictly speaking, this patch is not needed because
> usb_ep_autoconfig will call ep_matches which will
> override wMaxPacketSize for BULK endpoints only with
> the size associated with the endpoint setup by the udc driver.
> But if you want to rely on this, you may as well combine the
> full speed descriptor with the high speed descriptor to
> minimize confusion.
