Are you using bus powered devices? Bus powered device. Why does the drive still run fine with uas on other machines? Why did it run with uas also on the now failing machine, until something ha= d changed? What could be broken due to test with a longer 1 meter cable? Does uas have higher spec requirements to the USB bus? I thought it's just another protocol run on USB3 with SuperSpeed (5Gbps). Using that drive on t= he failing machine still works with the usb-storage module using the older Bul= k- only protocol.
