I think that's the reason one of my USB-C ports isn't working:
[ 5.849656] usb 3-4.4: new full-speed USB device number 11 using xhci_hcd
[ 5.851486] usb 3-4.4: Device not responding to setup address.

[ 6.266798] usb 3-4-port4: unable to enumerate USB device
I'm not sure if it's related, but I tweaked my ZFS settings by creating a /etc/modprobe.d/zfs.conf file with all the ZFS settings (rather than fetching them from /sys/module/zfs/parameters) and using that .conf file to increase the various prefetch and caches by 50%... it increased the data transfer speed so much that when I'm doing a file transfer to one USB drive, it spikes up to ~470 MB/s at the start, then stumbles down to ~270 MB/s, then the drive disconnects and reconnects.
I'll reset that .conf file to defaults and see if the problem persists.
Devs, let me know if you need any other logs.
[EDIT]
Ok, I backed off a bit on the ZFS settings... it's not quite as fast, but it's not causing the drive to spontaneously disconnect. Strange... it's a USB 3 port and a USB 3 drive, it should be able to sustain 470 MB/s. Perhaps that's just read speed, and during writing I just overwhelmed it?
