On Chrome OS we want to use USBguard to potentially limit access to USB
devices based on policy. We however to do not want to wait for userspace to
come up before initializing fixed USB devices to not regress our boot
times.

This patch adds option to instruct the kernel to only authorize devices
connected to the internal ports. Previously we could either authorize
all or none (or, by default, we'd only authorize wired devices).

The behavior is controlled via usbcore.authorized_default command line
option.

USB: remove the URB_NO_FSBR flag 2017-12-12T12:16:07+00:00 Alan Stern stern@rowland.harvard.edu 2017-12-11T16:58:21+00:00 aa15d3d257f9edcb8d15ed27e228d1c0080cb919 The URB_NO_FSBR flag has never really been used. It was introduced as a potential way for UHCI to minimize PCI bus usage (by not attempting full-speed bulk and control transfers more than once per frame), but the flag was not set by any drivers. There's no point in keeping it around. This patch simplifies the API by removing it. Unfortunately, it does have to be kept as part of the usbfs ABI, but at least we can document in include/uapi/linux/usbdevice_fs.h that it doesn't do anything.
