While the drives I have (PID 0xab45, "Backup+ Hub BK") are used without problem with very light loads, I'm starting to get annoyed when doing more serious work. Here is a series of messages (v4.14) I have when simply trying to balance 1 chunk of BTRFS data, ie. write 5 GiB, and waiting a long time in-between: Nov 12 16:15:35 Bidule kernel: sd 22:0:0:0: [sdaa]

I understand that latencies can climb to several seconds as the disks can do GC, and suspect that the issues (sometimes the USB reset doesn't work and a reboot is needed...) are due to some unawareness of that, but I don't know. There are several threads on distribution forums & bug trackers, but nothing really helpful, and I didn't see much on LKML.
