I expect that removing hardware does the same thing Also suspend current increases by around 15mA if that module is loaded. I tested with having everything disabled which is attached to that usb bus. System was GTA04A5 (with dm3730 processor and usb3322 phy) I know it has worked once, but I do not remember the version. The kernel config used can be found here: http://misc.andi.de1.cc/config-4.15.gz Regards Andreas BTW: I am at the FOSDEM, will probably spend a lot of time in the hw enablement devroom. So maybe ideas could be discussed directly. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
