USB HID descriptors may push/pop the current state to allow description of items residing in a so-called union. FreeBSD currently only supports 4 such push levels. If the push level is not restored within the processing of the same HID item, an invalid memory location may be used for subsequent HID item processing. Verify that the push level is always valid when processing HID items. Reported by: Andy Nguyen (Google) Sponsored by: Mellanox Technologies

Set the maximum exit latency to 0 for XHCI USB 3.0 devices, because we don't implement link power management, LPM. This fixes error code XHCI_TRB_ERROR_BANDWIDTH for isochronous USB 3.0 transactions. Submitted by: Horse Ma Sponsored by: Mellanox Technologies

Implement a detaching flag for the sound(4) subsystem to take appropriate actions when we are trying to detach an audio device, but cannot because someone is using it. This avoids applications having to wait for the DSP read data timeout before they receive any error indication. Tested with virtual_oss(8). Remove some unused definitions while at it.

Remove the power bit from the super speed root hub port status register because it clobbers the super speed link status when a device is in super speed mode. Currently the power bit is not needed for anything in the USB hub driver. This fixes USB warm reset for super speed devices. Tested by: Shichun.Ma@dell.com Sponsored by: Mellanox Technologies

In usb(4) fix a lost completion event issue towards libusb(3). It may happen if a USB transfer is cancelled that we need to fake a completion event. Implement missing support in ugen_fs_copy_out() to handle this. This fixes issues with webcamd(8) and firefox. Sponsored by: Mellanox Technologies
