* usblib: usb_device_get_string decoding fixes.Andrew Chant2017-12-182-23/+83
| | | | | | | | | | | | | | | usb_device_get_string converts incoming ucs-2 text to ascii by truncating the upper byte of each character. This is error prone. This patch introduces usb_device_get_string_ucs2 to access raw USB string descriptors, as well as changes usb_device_get_string to replace any non ascii character with '?'. Bug: 70163357 Change-Id: If8f98fee4be6ea75dc0f7ce7beba7fd7b6aabf88 Test: Connected & disconnected a NuForceDAC.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | in usb_device_open, if permission is denied for a USB device node, the current code retries read-only, then sleeps for a second before retrying. If the permission was changed to +rw between the two file opens, the device could be inadvertently opened read-only. Also, change the polling interval to 100ms. 1s is a long wait for a function on the critical path of a user interaction. Bug: 68337205 Bug: 68782236 Test: with debug messages enabled, connected & disconnected a USB audio headset. Saw the writeable file descriptor returned.

| * 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
