Android Phone Not Detected By SigmaKey

Hello, i would like to ask a question regarding connecting any android phone (sony, alcatel, motorola etc) to sigmakey, but software doesn’t detect phone automatically, after turning on usb debugging mode, i have to unplug phone and have to close software and have to reopen software so software can detect phone in adb platform,
no matter which phone i connect with computer, sigmakey doesn’t detect it automatically, i have to close software and reopen to connect phone.
can you please tell me what should i do so sigmakey can detect android phone automatically?? i don’t want to close and reopen software all the time, thanks.
