I found this in Documentation/usb/power-management.txt: "Note: Dynamic PM support for USB is present only if the kernel was built with CONFIG_USB_SUSPEND enabled (which depends on CONFIG_PM_RUNTIME). System PM support is present only if the kernel was built with CONFIG_SUSPEND or CONFIG_HIBERNATION enabled. (Starting with the 3.10 kernel release, dynamic PM support for USB is present whenever the kernel was built with CONFIG_PM_RUNTIME enabled. The CONFIG_USB_SUSPEND option has been eliminated.)" but I'm quite unsure how to change it. What about: "System PM support is present only if the kernel was built with CONFIG_SUSPEND or CONFIG_HIBERNATION enabled. Dynamic PM support for USB is present whenever the kernel was built with CONFIG_PM enabled. [Historically, dynamic PM support for USB was present only if the kernel had been built with CONFIG_USB_SUSPEND enabled (which depended on CONFIG_PM_RUNTIME). Starting with the 3.10 kernel release, dynamic PM support for USB was present whenever the kernel was built with CONFIG_PM_RUNTIME enabled. The CONFIG_USB_SUSPEND option had been eliminated.] Rafael -- 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
