2018-05-07usb-host: skip open on pending postload bhGerd Hoffmann
usb-host emulates a device unplug after live migration, because the device state is unknown and unplug/replug makes sure the guest re-initializes the device into a working state. This can't be done in post-load though, so post-load just schedules a bottom half which executes after vmload is complete. It can happen that the device autoscan timer hits the race window between scheduling and running the bottom half, which in turn can triggers an assert(). Fix that issue by just ignoring the usb_host_open() call in case the bottom half didn't execute yet.

2017-06-21usb-host: support devices with sparse/non-sequential USB interfacesSamuel Brian
Some USB devices have sparse interface numbering which is not able to be passthroughed. For example, the Sierra Wireless MC7455/MC7430: # lsusb -D /dev/bus/usb/003/003 | egrep '1199|9071|bNumInterfaces|bInterfaceNumber' Device: ID 1199:9071 Sierra Wireless, Inc. idVendor 0x1199 Sierra Wireless, Inc. idProduct 0x9071 bNumInterfaces 5 bInterfaceNumber 0 bInterfaceNumber 2 bInterfaceNumber 3 bInterfaceNumber 8 bInterfaceNumber 10 In this case, the interface numbers are 0, 2, 3, 8, 10 and not the 0, 1, 2, 3, 4 that QEMU tries to claim. This change allows sparse USB interface numbering. Instead of only claiming the interfaces in the range reported by the USB device through bNumInterfaces, QEMU attempts to claim all possible interfaces. v2 to fix broken v1 patch formatting. v3 to fix indentation.

2017-01-31hw/ppc/spapr: Fix boot path of usb-host storage devicesThomas Huth
When passing through an USB storage device to a pseries guest, it is currently not possible to automatically boot from the device if the "bootindex" property has been specified, too (e.g. when using "-device nec-usb-xhci -device usb-host,hostbus=1,hostaddr=2,bootindex=0" at the command line). The problem is that QEMU builds a device tree path like "/pci@800000020000000/usb@0/usb-host@1" and passes it to SLOF in the /chosen/qemu,boot-list property. SLOF, however, probes the USB device, recognizes that it is a storage device and thus changes its name to "storage", and additionally adds a child node for the SCSI LUN, so the correct boot path in SLOF is something like "/pci@800000020000000/usb@0/storage@1/disk@101000000000000" instead. So when we detect an USB mass storage device with SCSI interface, we've got to adjust the firmware boot-device path properly that SLOF can automatically boot from the device.

2016-06-13usb-host: add special case for bus+addrGerd Hoffmann
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 Armbruster
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.

2013-10-22usb-host-libusb: Fix reset handlingHans de Goede
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 Hoffmann
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>
