These bugs are in the Windows USB SDK version of the NoloVR drivers:
1) USB driver overwrites (and damages) SteamVR 'chaperone' configuration (a private file that should not be tampered with). This means that all HMDs (whether they are using Nolo or not) need to do room setup again whenever the Nolo USB driver is initialised (whether or not SteamVR is used). This is a serious bug that irritates users. There's no need for this, particularly when the software using Nolo (eg. iVRy) particularly doesn't want this behaviour. There is no way to opt out. I will modify the Nolo drivers I ship with my software to disable this 'feature', as I am tired providing support for this issue.
2) Default tracking center is 90 degrees off (anti-clockwise) or 270 degrees off (clockwise). Every time Nolo hardware is initialised the controller 'recenter' button needs to be clicked on each controller, several times, before controller and headset marker are centered towards the base station, even though the base station tracking position is correct (and so it's a bug that the devices do not start with center pointing towards base station)@admin
