hi all: below patch introduce unbind and rebind interfaces during usb reset https://lists.ubuntu.com/archives/kernel-team/2014-April/042177.html "If a driver claims additional interfaces, the claim may fail because the old binding instance may still own the additional interface when the new instance tries to claim it. " After usb_reset_device, the whole enumeration will run again, why this patch say the previous solution will be fail to claim additional interface? thanks for your help in advance, -- 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
