12 On some Kinect devices where the desired configuration is already the
13 currently active one libusb_set_configuration() fails in some way
14 causing the subsequent bulk transfer to fail, and the program to exit,
15 with this message:
16
17   libusbx: error [op_set_configuration] failed, error -1 errno 110
18   About to send: 09 20 02 06 01 00 00 00 60 00 00 00 00 00 00 00 15 00 00 00 00 00 00 00
19   libusbx: error [submit_bulk_transfer] submiturb failed error -1 errno=2
20   Error: res: -1    transferred: 0 (expected 24)
21
22 Only set the desired configuration if it hasn't been set already.
23 This prevents the problems from above.
24
25 Do the configuration check as illustrated in
26 http://libusbx.sourceforge.net/api-1.0/caveats.html that is by checking
27 that the current configuration is still the desired one after claiming
28 the device.
