But first, can you have me check if your ID wakeup is enabled? I can have a test at mx28evk. Is it current upstream kernel can boot mx28evk run? I have a RevC board, I would like to know if any patches needed. > > --- a/arch/arm/boot/dts/imx28-m28evk.dts > +++ b/arch/arm/boot/dts/imx28-m28evk.dts > @@ -240,6 +240,8 @@ > > ahb@80080000 { > usb0: usb@80080000 { > + dr_mode = "otg"; > + phy_mode = "utmi"; > vbus-supply = <®_usb0_vbus>; > pinctrl-names = "default"; > pinctrl-0 = <&usbphy0_pins_a>; > > --------------------------- > > - MX23 UDC issue > > I found a workaround.

It seems not reasonable, the same question for mx23evk, it can run well with current kernel? I have no board on hand, let me see if I can find one. -- Best Regards, Peter Chen -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
