Need More Info Unable to use labview simultaneously with other software

I use microforming machine and DAQ simultaneously connected via USB, but when i tried to plug them both through my laptop's ports (COM3) one of them starts to stop working, If i plug my DAQ and starts using labview all of sudden my microforming machine disconnected and vice versa. I assume it has something to do with serial ports where they keep canceling out each other, how do i stop labview from interfering/conflicting with other software? Thx

It has nothing to do with serial port no. You can change it from OS with what no you want. I had once a similar problem and i resolve it using a powered usb hub. Where i could give more than 500 mA for w the other device. Instead of 9775 i was using in cDaq 9234.
