The device class for the nolo head tracker was set to an HMD. This causes problems on dependant projects like Monado which expects HMDs to include display devices. The nolo head tracker is not an HMD so this commit changes it to a generic tracker class.
Some VR Devices' data is routed through another device. This commit updates the simple program to allow polling of such devices. This commit also adds a feature for allowing the user to select the device that is polled via the command line first showing the device ids and then promting the user to select the device to be polled.
When the nolo base station is connected, if it is the first device returned by the hid_enumerate, than OpenHMD exits because the STATION is the wrong device. This code correctly iterates through the linked list ignoring the STATION if it is connected and ensures that the other NOLO devices are registered.
The trackpad reports values with the range of [0,255] for x and y axis. Monado expects a range of [-1, 1] for both axis. This commit normalizes the output for the trackpad to [-1, 1]. The controller y and z axis were assigned to the incorrect values (swapped). This commit only changes the y and z axis for the controllers as the head tracker appears to be correct.
The gyo and acceleration data from nolo was reversed. This caused the code to swap the variable names. It could be that in previous nolo firmware the data formatting was different than the latest firmware? This commit fixes the gyo and acceleration when retreiving those values from the nolo controllers.
