I don't know if this is an issue but I used to connect my USB hub in my USB 2.0 port with keyboard and mouse plugged in the hub. Back then, it seems to work fine and no issues encountered. But today, when I plugged both of my peripherals in my USB hub (plugged in to the USB 2.0 port), the mouse buttons are not working. It seems I need to spam clicking it in order to function, it is like a delay or something. I tried unplugging my keyboard and the mouse buttons works fine now. Also, I tried plugging in my USB hub to another port, this time to the USB 3.1 Gen 1 Type-A port. And it works fine, mouse buttons are now functioning well with no delays and also my keyboard is working fine. Both are plugged in to the USB hub.
Now back to my question, Does a USB 2.0 and USB 3.1 Gen 1 Type-A have different speed and capacity? And how come plugging in my USB hub in USB 2.0 used to work fine back then but today It doesn't anymore. I'm really don't think if my USB ports are faulty since I used to plug my peripherals directly and it seems to work fine.
I haven't tried plugging in a USB hub with peripherals connected to my other laptop. I guess I'll try and see if I have the same issuse.
Thank you in advance for the answers
