I see a disconnect from port 4:1 of some un-enumerated device then
connect to port 2:1 with UAS blacklist:
[ 281.814757] usb 4-1: USB disconnect, device number 2
[ 283.418292] usb 2-1: new SuperSpeed USB device number 2 using xhci-hcd
[ 482.153319] usb 2-1: USB disconnect, device number 2
[ 484.250856] usb 2-1: UAS is blacklisted for this device, using
usb-storage instead
[ 484.250901] usb-storage 2-1:1.0: USB Mass Storage device detected
[ 484.258055] usb-storage 2-1:1.0: Quirks match for vid 174c pid 55aa: c00000
[ 484.264432] scsi host1: usb-storage 2-1:1.0
Are you peraphs changing the quirks in the modules config and reattach
the device?
Anyhow I see some strange reset from the USB host. What is this
device? Perhaps some self-powered external HDD?
