Fabio, any chance you can try ?
Here is the debug log for "usb reset": http://paste.ubuntu.com/14865306/ And here the log for the file transfer (different thumb drive and therefore different messages than posted before): http://paste.ubuntu.com/14865349/ The only changes to U-Boot I made is adding my board configuration (derived from Freescale SabreSD config). The only difference from the SabreSD config related to USB is, that I have set CONFIG_USB_MAX_CONTROLLER_COUNT to 2 instead of 1. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
