I'am using Tascam uss 122 for theater caliberation purpose. With the Tascam i'am using Isemcon microphone. And the Laptop is Dell with Windows 7 OS. The problem that i'am getting is while doing the calibration the hardware automatically gets disconnected for sometime. & it reconnects after sometime. I've tried it using with Vista OS & there it works absolutely fine. Kindly give me any suggestion as what to do to solve this issue.
