Public bug reported:
I have the following hardware:
* Dell XPS 13, which has two USB ports—one USB 2.0, one USB 3.0.
* Sans Digital MS4UM+B (http://www.sansdigital.com/mobilestor/ms4umplusb.html)
with four hard disks.
I am trying to transfer data between two of the disks in the enclosure,
using dd.
When I connect the enclosure to the USB 2.0 port, dmesg contains:
[ 892.056502] usb 3-1: new high-speed USB device number 3 using xhci_hcd
[ 892.073556] usb 3-1: New USB device found, idVendor=152d, idProduct=0551
[ 892.073567] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=5
[ 892.073573] usb 3-1: Product: USB to ATA/ATAPI Bridge
[ 892.073578] usb 3-1: Manufacturer: JMicron
[ 892.073582] usb 3-1: SerialNumber: DCA1861915FF
…and I can transfer hundreds of gigabytes without issue, at USB 2.0 speeds (20
MB/s).
When I connect the enclosure to the USB 3.0 port, dmesg contains:
[ 658.873399] usb 4-2: new SuperSpeed USB device number 2 using xhci_hcd
[ 658.890861] usb 4-2: New USB device found, idVendor=152d, idProduct=0551
[ 658.890872] usb 4-2: New USB device strings: Mfr=1, Product=2, SerialNumber=5
[ 658.890878] usb 4-2: Product: USB to ATA/ATAPI Bridge
[ 658.890883] usb 4-2: Manufacturer: JMicron
[ 658.890887] usb 4-2: SerialNumber: DCA1861915FF
…and I invariably experience a kernel panic shortly after data transfer begins.
I attach two screenshots. If I can manage to probe dd (sudo killall --signal
USR1 dd), the transfer appears to be going at USB 3.0 speeds.
The enclosure was not powered on when I ran 'ubuntu-bug linux' to report
this, so I'll attach another dmesg showing the device being attached to
first the USB 3.0, then the USB 2.0 port.
