Hi, i am using Acer Swift SFX 14 - 41G
Today one of my USB 3.0 port can't detect some of the devices
My USB port can detect device like my flash drive and my HDD (USB 3.0), but my USB unable to detect my other device such as pen tablet, mouse, printer (any devices that uses 2.0). my other devices isn't broken because it can be use with the other USB (But i need to use pentab and mouse at the same time for efficiency)
The USB still giving the power to my device, but the input or output isn't shows up on my device
How do i fix this? i already try to uninstall and reinstall from device manager, but it wouldn't help. any ideas?

+i don't know this information is necessary or not, the "broken" USB is "Always-On USB"

The only solution I can come up with is to reinstall your USB driver on Device Manager, under Universal Serial Bus Controllers. Uninstall them and restart your PC.

Always-On might be why it can still charge your USB 2.0 devices and not detect them.
