* libusbhost: It's no longer assumed that "bus/usb" exists once "bus" was createdZiv Hendel2013-08-261-3/+16
| | | | | | | | | | On some devices there is a slight delay between the creation of "/dev/bus" and "/dev/bus/usb". Previously, the code assumed that both are created in the same time which caused "watch_existing_subdirs" to fail and libusbhost to stop working until the device is rebooted. The fix will setup an inotify event on the creation of the "bus/usb" so it will not be missed once it's created. Change-Id: I17f06dd167e61573307425e48898e12ebc954093

* libusbhost: generates a static libraryGuillaume Ranquet2012-12-101-0/+10
| | | | | | | | | | due to limitations of the droidboot OS used for POS, there's a need for a static libusbhost library. this permits to include libusbhost in droidboot Change-Id: I0f0c07817ad19b773b466b69fd6e997877d41b34 Signed-off-by: Guillaume Ranquet <guillaumex.ranquet@intel.com>
* libusbhost: permits client polling on inotify wdGuillaume Ranquet2012-12-101-65/+105
| | | | | | | | | | | | Modify libusbhost to expose the inotify watch descriptor to clients This modification permits clients to add the watch descriptor to their polling loop so that they don't have to use a dedicated thread only for libusbhost.

* libusbhost: Fix USB device discovery on bootBenoit Goby2012-08-021-15/+43
| | | | | | | | On some devices, /dev/bus/usb does not exist on boot, it is only created when the otg port is in host mode. Use inotify to detect when /dev/bus/usb is created and then start watching subdirectories. Change-Id: Ic1472a5ea7a7118cdbb560cc7071ade9bcee753a
* libusbhost: Fix possible missed "device added" notificationBenoit Goby2012-08-021-20/+43
| | | | | | | | | | When a new bus is added, check for existing devices in the bus directory, since devices may have been added before calling inotify_add_watch. Also add missing inotify_rm_watch calls. Change-Id: Ie69fc995a3e8b18431099b252be86f0054fe5531
