We’ve been having an issue at work with our data wrangling boxes and some older USB3 drives, specifically on Debian. It turns out the UAS module breaks some drives from mounting and they never get assigned a device ID correctly. If you plug the USB3 drive in to a USB2 port though it will mount fine but then ou lose all that lovely speed!
The fix is this (as root, as I live dangerously):
echo “options usb-storage quirks=059f:104b:u” > /etc/modprobe.d/blacklistUAS.conf
Obviously swap out your USB ID for your device. You can find it by doing `lsusb`
Bus 002 Device 002: ID 059f:104b LaCie, Ltd

Don’t forget to add the :u after your ID, else it will not work.
