I haven't any problems with TrackIR on my spec from a long time till the yesterday

I'm user of Logitech G930 headphones too (Soft and drivers 8.58) and from yesterday when I'd like to connect headset to USB and after this when I run software of TrackIR (Soft and drivers 5.2.2) the TrackIR isn't detected by software. When I run soft of TiR and I didn't have headset in USB (speakers only) no any problems with TrackIR.
It looks like USB problem for me (when Track IR and Headset USB are connected in the same time). I reinstalled soft of TiR and soft of sound card and headset 2 times and the problem still exists but from a long time no any problems with this combination... I didn't install the new soft or other program from few days.
How to solve it?
