* Remove incorrect comment about how autoconf(9) works and documentmpi2014-07-121-16/+3

* Only detach the USB device you disconnected, fix a regression reportedmpi2014-07-121-3/+7
| | | | | | | by guenther@. While here set the dying flag of the disconnected device so that most of the DVACT_ACTIVATE handlers can go.
* Always assign the device address found by the USB stack even if itmpi2014-07-101-4/+8
| | | | | | | | | | | | | | does not match the hardware address. This change only matters for xHCI buses where the controller assigns device addresses. But it is the simplest way to comply with the stack requirement of assigning the first `logical' address to the root hub device. Device addresses are not much used anyway and a cleanup will follow to avoid possible confusions. This makes usbdevs(8) correctly report devices connected to xhci(4).
* autoconf(9) is your friend and it knows you more than you think. Itmpi2014-07-091-51/+28
| | | | | | | | | even knows your children! So let him handle the seperation correctly. Do not rewrite your own custom config_detach_children(9) and as a bonus start removing the usbd_port tentacles from the stack. ok pirofti@, yuo@, miod@, deraadt@
* Adds an optional bus function to set the address of a new device andmpi2014-07-091-18/+30
| | | | | | | | | explicitly set it when required. Right now xhci(4) does not need such function because it assigns addresses when the first pipe of a device is opened. ok yuo@, pirofti@

* Remove a hack to update the address and packet length for every devicempi2014-01-151-2/+19
| | | | | | | | | request and instead re-open the default pipe with updated values when attaching a new device, adapted from FreeBSD r162977. This fixes a problem where the controller could have cached the previous values and would fail to get the device descriptor, leaving the device unrecognized with a message like: "device problem, disabling port n".

* cap device's speed to the parent's one if higher. from FreeBSD.fgsch2009-01-141-1/+12

* change a device descriptor get logic during the enumeration process.yuo2008-11-241-7/+37
| | | | | | | | | | | | Some device could not handle the device descriptor request with short bLength (less than the device descriptor size(18 byte)). To handle such kind of devices, add complemental request loop to current logic. (memo: and I also found a device which can not response to any device descriptor request. It always returns only 8 byte-length head of the descriptor for 1st query. This is the reason why the device descriptor loop of this usb subsystem start with 8-byte length query.)

| | | | | | | | and then the whole string based on the returned size, not just one byte. The Lexar card reader kindly loaned by Denis Doroshenko (denis dot doroshenko at gmail.com) it's happy now, and after further inspection it's what other OSs do. Discussed with yuo@. krw@ yuo@ ok.

| | | | | | | | | | | add new quirk entry for uvideo which is required isoc transfer. Some usb2.0 devices use isochronous transfer but current usb subsystem does not support isoc transfer in ehci(usb2.0) bus. This patch introduce new psuedo usb hub request UHF_PORT_DISOWN_TO_1_1 to handover the device to ehci to usb1.1 bus(ohci or uhci). ok mglocker@ deraadt@ fgsch@
