Actually, there was success, at least for the command I was trying to fix: [ 294.617975] xhci_hcd 0000:03:00.0: Slot ID 1 Input Context: [ 294.617977] xhci_hcd 0000:03:00.0: @ffff880135d4b000 (virt) @ffffc000 (dma) 0x000000 - drop flags [ 294.617979] xhci_hcd 0000:03:00.0: @ffff880135d4b004 (virt) @ffffc004 (dma) 0x000003 - add flags ...

At this point, it's not an xHCI driver problem. Instead your device disconnects on its own, and you get this lovely oops message from the scsi layer: [ 323.957501] hub 4-0:1.0: port 1, status 02c0, change 0041, 5.0 Gb/s [ 323.957504] usb 4-1: USB disconnect, device number 2 [ 323.957506] usb 4-1: unregistering device [ 323.957508] usb 4-1: unregistering interface 4-1:1.0 ...
