Here is a work around that prevents USB3.0 timeout occurring under latest Mint and Ubuntu distros
Im my case I have a Samsung T3 SSD drive, the vendor ID and product ID can be seen in the /var/log/syslog when connecting the device:
usb 4-1: New USB device found, idVendor=04e8, idProduct=61f3
usb 4-1: New USB device strings: Mfr=2, Product=3, SerialNumber=1
usb 4-1: Product: Portable SSD T3
usb 4-1: Manufacturer: Samsung
So to turn off uas for idVendor=04e8, idProduct=61f3 you can do this
su
echo "options usb-storage quirks=04e8:61f3:u" > /etc/modprobe.d/ignore_uas.conf
locale-gen --purge --no-archive
update-initramfs -u
reboot
Should be all good again
