Does this bug happen for people after a USB drive has spun down and the computer tries to access it? My USB freezing issue goes away if I disable UAS for a particular drive. It works fine with UAS until it spins down but the USB subsystem freezes when it tries to spin it up, requiring me to reboot the PC and power cycle the drive.

To disable UAS for the drive, first find its identifier with the lsbusb command. For example mine looks like this, ie with identifier 1058:1230:

Bus 002 Device 003: ID 1058:1230 Western Digital Technologies, Inc. My Book

Add a file like /etc/modprobe.d/usb_storage.conf with the contents and the appropriate identifier:

options usb_storage quirks=1058:1230:u

and run "sudo update-initramfs -u -k all" and reboot.
