Linux and USB 3 Enclosures

If you have trouble with your USB 3 Disk with Linux, check your /var/log/messages or dmesg. If you find something like this:

[ 4205.587316] sd 6:0:0:0: [sdh] tag#11 uas_eh_abort_handler 0 uas-tag 12 inflight: CMD OUT 

The you have a device that has Problems with UAS. Create a file /etc/modprobe.d/disable_uas.conf with content:

options usb-storage quirks=0x174c:0x5106:u
options usb-storage quirks=0x174c:0x5136:u
options usb-storage quirks=0x0bc2:0xab20:u
options usb-storage quirks=0x0bc2:0xab21:u

Then rebuild initrd and reboot. If this does not work, check if the vendoe and device id is missing in the lis and add a line. Find the ids with lsusb.
