* Provide the USB device release number along with other parametersIan Dowse2005-08-231-4/+4
| | | | | | | | | | | so that devd can match on it. This field was already available to usbd and is used by a number of usbd.conf entries, so now it is possible to transfer those entries to devd.conf. Submitted by: Anish Mistry Notes: svn path=/head/; revision=149398

* Merge recent USB2/EHCI related changes from NetBSD:Ian Dowse2004-11-031-4/+44
| | | | | | | | | | | | | | | | | | | o Reduce the interrupt delay to 2 microframes. o Follow the spec more closely when updating the overlay qTD in the QH. o No need to generate an interrupt at the data part of a control transfer, it's generated by the status transfer. o Make sure to update the data toggle on short transfers. o Turn the printf about needing toggle update into a DPRINTF. o Keep track of what high speed port (if any) a device belongs to so we can set the transaction translator fields for the transfer. o Verbosely refuse to open low/full speed pipes that depend on unimplemented split transaction support. o Fix various typos in comments.

* We don't need a uhub_child_detached() routine now that we don't detachWarner Losh2004-09-091-34/+2
| | | | | | | | | | | | | | | | | device_t instances when no driver attaches. They are left around, and we need to remember them. # The usbd_device_handle->subdevs[] array likely is completely bogus # at this point, but one change at a time, since its removal will need # to have similar code replace it extracted from newbus.

* Next step in making usb more newbus:Warner Losh2004-08-141-26/+14
| | | | | | | | | | | | | | | | o reprobe children when a new driver is added to uhub o fix the usbd_probe_and_attach to set the ivars to a malloc'd area, as well as freeing the ivars on child destruction. o Don't delete children that don't attach. Evidentally, the need to do this is a common misconception. o minor formatting foo that may violate style(9) at the moment, but keeps the diffs against my p4 tree smaller. This does not solve the ugen gobbling things up problem, but the fixes I have for that expose bugs in other parts of the tree... Notes: svn path=/head/; revision=133730
* Make the USB subsystem unloadable and detachable, though currentlyIan Dowse2004-08-021-1/+2

* MFp4:Warner Losh2004-07-221-30/+29
| | | | | | | | | | Improve child_detached a little and make it conform better to style(9). Also, improve comment about what we'll be doing in the future about driver_added. Soon it will be possible to kldload usb drivers and have them attach w/o a need to disconnect/reconnect them. Notes: svn path=/head/; revision=132558

| | | | | | | | | | | | as otherwise the junk it contains may cause uhub_explore to give up without ever trying to restart the port.

In this case, Descriptor Type is 0x29 (UDESC_HUB), Descriptor Index should be 0. If I don't do a check (dev->address > 1 ... ), root hub fails. A new Cytronix 4-port USB 2.0 Hub (Cypress CY7C65640 chip) now works after this patch.
