Hi Alexander Holler, is EHCI on omap3 already working? On my beagleboard xM usb start hangs at this position in method ehci_hcd_init: + /* perform TLL soft reset, and wait until reset is complete */ + writel(OMAP_USBTLL_SYSCONFIG_SOFTRESET, + OMAP3_USBTLL_BASE + OMAP_USBTLL_SYSCONFIG); regards, chris.
