2016-06-13usb-host: add special case for bus+addrGerd Hoffmann1-4/+52
This patch changes usb-host behavior in case we hostbus= and hostaddr= properties are used to identify the usb device in question. Instead of adding the device to the hotplug watchlist we try to open directly using the given bus number and device address. Putting a device specified by hostaddr to the hotplug watchlist isn't a great idea as the address isn't a fixed property. It changes every time the device is plugged in. So considering this case as "use the device at bus:addr _now_" is more sane. Also usb-host will throw errors in case it can't initialize the host device. Note: For devices on the hotplug watchlist (hostport or vendorid or productid specified) qemu continues to ignore errors and keeps monitoring the usb bus to see if the device eventually shows up.

2016-03-22include/qemu/osdep.h: Don't include qapi/error.hMarkus Armbruster1-0/+1
Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little. More work is needed for that one. Signed-off-by: Markus Armbruster <armbru@redhat.com> [Fix compilation without the spice devel packages. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2015-11-03usb-host: fix usb3ep0quirk testGerd Hoffmann1-1/+1
usb->speed is the usb speed the device is actually running on in the qemu emulation (i.e. from the guests point of view). So when plugging usb3 devices into ehci hostadapter this is HIGH not SUPER. To figure whenever the host talks to the device with superspeed we have to check speedmask instead and see whenever the superspeed bit is set there.

Quoting from: linux/Documentation/ABI/stable/sysfs-bus-usb: Note that some devices, in violation of the USB spec, have a configuration with a value equal to 0. Writing 0 to bConfigurationValue for these devices will install that configuration, rather then unconfigure the device. So don't compare the configuration value against 0 to check for unconfigured devices, instead check for a LIBUSB_ERROR_NOT_FOUND return from libusb_get_active_config_descriptor().

2013-10-22usb-host-libusb: Fix reset handlingHans de Goede1-6/+4
The guest will issue an initial device reset when the device is attached, but since the current usb-host-libusb code only actually does the reset when udev->configuration != 0, and on attach the device is not yet configured, the reset gets ignored. This means that the device gets passed to the guest in an unknown state, which is not good. The udev->configuration check is there because of the release / claim interfaces done around the libusb_device_reset call, but these are not necessary. If interfaces are claimed when libusb_device_reset gets called libusb will release + reclaim them itself. The usb_host_ep_update call also is not necessary. If the reset succeeds the original config and interface alt settings will be restored. Last if the reset fails, that means the device has either disconnected or morphed into an another device and has been completely re-enumerated, so it is treated by the host as a new device and our handle is invalid, so on reset failure we need to call usb_host_nodev().

2013-04-16use libusb for usb-hostGerd Hoffmann1-0/+1449
Reimplement usb-host on top of libusb. Reasons to do this: (1) Largely rewritten from scratch, nice opportunity to kill historical cruft. (2) Offload usbfs handling to libusb. (3) Have a single portable code base instead of bsd + linux variants. (4) Bring usb-host support to any platform supported by libusbx. For now this goes side-by-side to the existing code. That is only to simplify regression testing though, at the end of the day I want remove the old code and support libusb exclusively. Merge early in 1.5 cycle, remove the old code after 1.5 release or something like this. Thanks to qdev the old and new code can coexist nicely on linux. Just use "-device usb-host-linux" to use the old linux driver instead of the libusb one (which takes over the "usb-host" name). The bsd driver isn't qdev'ified so it isn't that easy for bsd. I didn't bother making it runtime switchable, so you have to rebuild qemu with --disable-libusb to get back the old code. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
