Here's an idea, If the customer adds a device to a specific receiver, leave it there! Don't be a hateful idiot and undo what the customer intentionally did. There's a reason we all hate logitech. Your software is beyond pathetic. You hate your customers, so we hate you. Open source options, options+ (what a misnomer), and the unifying software and we at least can undo your malicious customer hating idiotic choices. I don't care what language it's written in, I'll learn it just to undo what you idiots ruin. Send your developers back to whatever preschool you stole them from and let them have recess.
