This adds USB support to Set and Get the Device Configuration. These control transfers are standard device requests that need to be added in order to behave properly for USB suspend/resume (and in general). Before this CL, the Get command always failed and the Set command had no effect internally. With this CL it works. Note that this particular change only supports ONE configuration for the Cr50. If/when we add additional configuration descriptors, we'll need to update it again. BUG=chrome-os-partner:50721 BRANCH=none TEST=make buildall; manual tests on Cr50 This CL includes a test program. Connect the Cr50 to the build host, and use that program to read and change the configuration. cd test/usb_test make ./device_configuration ./device_configuration 0 ./device_configuration 1 ./device_configuration 2 You may need to use sudo if your device permissions aren't sufficient.

These tests need to be built and run by hand, unless/until we set up a lab with known devices attached to a test host.
