Hi all, I'm now using a new device usb3
But hot-pluging it drive you nowhere
dmesg full of
xhci_hcd 0000:04:00.0: WARN: Stalled endpoint
Does the device still work properly, even with that message?
Not everything on the device stall and it's just loose.
What do you mean by that?
First plug I was thinking it's works so I
fired fdisk and build a partition.
Using w to write on it, are now running, even if I disconnect the device after having

[706143.649079] xhci_hcd 0000:04:00.0: WARN: Stalled endpoint
So it works properly?
Is this a USB 3.0 storage device only? If so, we don't have a Linux
driver for it (no operating system does), so it might not work to its
full capabilities yet.
USB 3 is still under heavy development. The basics are there, but the
full speed improvement is still being worked on (see the changes in the
linux-next tree for examples of major speedups and lots of bug fixes.)
If you drop back to USB 2.0 controller speeds, does the device run
Ok we have done so more test on a same motherboard, with 11.3
USB-3 is working directly ( WARN: stalled endpoint is always here ) but hardrive are
correctly detected and mounted
Made with a 160GB + 1TB .
With the 2TB tried before, there a trouble when try directly (hot-plugging in the
Have error I/O code -71
After powering off the usb docking, disk 2TB inside it, power on, it works as expected.
We retry formatting & transfering for this disk (2TB) and everything seems to work.
So as it's too much hard to reproduce, I don't create a bug report.
I will wait a second failure, with clear errors that can be reproduce, I come back to
