I'm curious now, am I the first one who has ever tested uas on usb2?
Ni, I've tested it myself too, including running an entire distro

I tested with lot of values. I'm not totally sure but it looks the 31
is max number where it is still stable to create an ext4 filesystem.
Thanks, that is good to know. Can you try the following patch instead
of changing can_queue ? :
diff --git a/drivers/usb/storage/uas.c

Disconnection issues like you are seeing are typical for drawing
too much power from the port. Using uas as the dmesg shows you
are will allow us to send more commands to the disk at once
(which is a good thing, it is faster) and as such will increase
power consumption.
Maybe the too
Hello,
I don't think it is a power issue.
I'm using on desktop PC on usb2 port with just a simple cable but the
disk (WD5000LPVX) only consumes 1.4 Watts (read/write) and it is
stable on Windows.

Says it uses 1.4 Watts
A usbmon trace might be useful. See Documentation/usb/usbmon.txt in
the kernel source for instructions.

Hello,
I have some problems with Jmicron JMS567 (Sata 6 Gb/s - USB3.0) mobile rack.
I tried on different kernels:

I got the following errors when I ran a mkfs.ext4 command and then the
device disappeared.

Laszlo, you can try specifying the quirks=152d:0567:u module
parameter for usb-storage. I don't know if that will help, but it
might.
What can the problem be?
There's no way to tell from just this information.
Unfortunately it did not help.
Is there any other information you need?
