把arch/arm/mach-s3c6410/mach-smdk6410.c文件中的:
#ifdef USB_HOST_PORT2_EN
#define OTGH_PHY_CLK_VALUE (0x60) /* Serial Interface, otg_phy input clk 48Mhz Oscillator */
#else
#define OTGH_PHY_CLK_VALUE (0x20) /* UTMI Interface, otg_phy input clk 48Mhz Oscillator */
改爲:
#ifdef USB_HOST_PORT2_EN
#define OTGH_PHY_CLK_VALUE (0x60) /* Serial Interface, otg_phy input clk 48Mhz Oscillator */
#else
#define OTGH_PHY_CLK_VALUE (0x0) /* UTMI Interface, otg_phy input clk 48Mhz Oscillator */
