      Move fields from USBHostDevice to USBDevice.
      Add bits to usb-desc.c to fill them for emulated devices too.
      Also allow to set configuration 0 (== None) for emulated devices.

      usb-host: rip out legacy procfs support · 097db438
      Gerd Hoffmann 提交于
      This patch removes support for parsing /proc/bus/usb/devices for device
      discovery.  The code lacks a few features compared to the sysfs code and
      is also bitrotting as everybody has sysfs these days.
      
      This implies having sysfs mounted is mandatory now to use the usb-host
      driver.  udev isn't required though.  qemu will prefer the udev-managed
      device nodes below /dev/bus/usb, but in case this directory isn't preset
      qemu will use the device nodes below /proc/bus/usb (default usbfs mount
      point).
      
      Bottom line: make sure you have both sysfs and usbfs mounted properly,
      and everything should continue to work as it did before.

      usb-host: properly release port on unplug & exit · c75fead6
      Gerd Hoffmann 提交于
      Factor out port release into a separate function.  Call release function
      in exit notifier too.  Add explicit call the USBDEVFS_RELEASE_PORT
      ioctl, just closing the hub file handle seems not to be enougth.  Make
      sure we release the port before resetting the device, otherwise host
      drivers will not re-attach.

      Fix parse of usb device description with multiple configurations · 7279a85f
      Cao,Bing Bu 提交于
      Changed From V1:
      Use DPRINTF instead of fprintf,because it is not an error.
      
      When testing ipod on QEMU by He Jie Xu<xuhj@linux.vnet.ibm.com>,qemu made a assertion.
      We found that the ipod with 2 configurations,and the usb-linux did not parse the descriptor correctly.
      The descr_len returned is the total length of the all configurations,not one configuration.
      The older version will through the other configurations instead of skip,continue parsing the descriptor of interfaces/endpoints in other configurations,then went wrong.
      
      This patch will put the configuration descriptor parse in loop outside and dispel the other configurations not requested.

      usb-host: add usb_host_do_reset function. · c7662daa
      Gerd Hoffmann 提交于
      Add a special function to reset the host usb device.  It tracks the time
      needed by the USBDEVFS_RESET ioctl and prints a warning in case it needs
      too long.  Usually it should be finished in 200 - 300 miliseconds.
      Warning threshold is one second.
      
      Intention is to help troubleshooting by indicating that the usb device
      stopped responding even to a reset request and is possibly broken.

      usb-host: fix host close · 39fba3ad
      Gerd Hoffmann 提交于
      The whole usb_host_close() function is skipped in case the device is not
      in attached state.  This is wrong though, only then usb_device_detach()
      must be skipped, all other cleanup (especially device reset and closing
      the file handle) still needs to be done.  There are code paths where
      usb_host_close() is called with the device in detached state already.
      
      This fixes usb-host devices not being released and returned to the host
      after removing them with device_del.

      usb: use iovecs in USBPacket · 4f4321c1
      Gerd Hoffmann 提交于
      Zap data pointer from USBPacket, add a QEMUIOVector instead.
      Add a bunch of helper functions to manage USBPacket data.
      Switch over users to the new interface.
      
      Note that USBPacket->len was used for two purposes:  First to
      pass in the buffer size and second to return the number of
      transfered bytes or the status code on async transfers.  There
      is a new result variable for the latter.  A new status code
      was added to catch uninitialized result.
      
      Nobody creates iovecs with more than one element (yet).
      Some users are (temporarely) limited to iovecs with a single
      element to keep the patch size as small as possible.
