This board doesn't have a 48Mhz clock, so I set the reference clock in the USB PLL to a 12Mhz external crystal (see patch). Still, I'm having trouble getting it to work; I'm seeing these messages (see attachment for full log): s3c-hsotg s3c-hsotg: s3c_hsotg_rx_data: FIFO 8 bytes on ep0 but no req (DxEPCTl=0x00028000) hub 1-0:1.0: connect-debounce failed, port 2 disabled This looks like the hardware is configured correctly, but the currently-in-use gadget isn't setting up an EP0 RX transfer? I've tried Mass Storage, serial, Ethernet, ... gadgets and they all give the same errors. Any hints/pointers would be welcome!
