HP India — External USB Microphone Not Working with Laptop

Recently, I bought 4 HP Laptops for my Call Center and when I connected USB microphone with the laptop, two of them were working and two of them are not working. I tried several updates. Removed the headphone driver and re-install it, but nothing works for me. So, I tried connecting to the HP Support center, and they told me to update the BIOS of the system. I updated it but not helped me. After that I contacted HP WhatsApp support team, the message from their said is like a joke... They keep saying it is the problem with the external device ... They mean the headphone. I connected the headphone with other laptops, and it is working fine. I sent them a video to understand what is the problem, but even they are saying "we are not supporting external devices". 4 Laptops of same brand and 2 of them are not taking USB microphone, and they are blaming the USB microphone that works with other two laptops. Bad service from an reputed company called HP.
