Ok, I see the point. The above patch should not bring any regression, since if MPS < maxpacket(ep), then we will set the descriptor's wMaxPacketSize as ep->ep.maxpacket. I'm just wondering if you could share the wMaxPacketSize of your platform (lsusb -v on HOST). In my case it is: wMaxPacketSize 0x0200 1x 512 bytes -- Best regards, Lukasz Majewski Samsung R&D Institute Poland (SRPOL) | Linux Platform Group _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
