After a kernel update in my manjaro deepin, my USB 3.0 external storage device stopped working, only working in a 2.0 USB. This is related with the idle discovery configuration in tlp, i really don't know why but here's how to solve it.
Connect your device and run the command lsusb in terminal to list the usb devices. Copy your device ID.
Open tlp configuration with your prefered text editor, in this example i'll use gedit. Run in terminal:
sudo gedit /etc/default/tlp
Add the line with your device ID like:
USB_BLACKLIST="YOURDEVICEID"
In my case:
Reboot your PC and your device should be properly working.
