Hello,
my Sabrent DS-SC4B keeps disconnecting on my Ubuntu installation under load. So it stays connected while no Data is accessed, but completly kills the USB Host Controller when copying data to the HDD.
[ 9995.468704] xhci_hcd 0000:01:00.0: ERROR unknown event type 15

[10000.471396] xhci_hcd 0000:01:00.0: HC died; cleaning upI also added the suggested quirks for the chip (diabling UAS):
/etc/modprobe.d/disable-uas.conf
options usb-storage quirks=174c:55aa:u
and adding
/etc/modules-load.d/usb-storage.conf
options usb-storage quirks=174c:55aa:t
This is the bootup dmesg:
