USB Pendrive not detecting

Hello,

I am working on Rock 3A board where I’ve installed Ubuntu 20.04 OS. I am using two variants, one is server OS and another one is Ubuntu MATE desktop version.

I am trying to connect USB pendrive (16 GB) on both hardwares. But the issue is, server OS is not detecting pendrive (or I am sure the way I’m checking ). In desktop OS I can see the pendrive is detecting .

Is there any drivers should I’ve to update before injecting pendrive?

Can anyone please explain the procedure to check usb drivers.
