Hi,
I have started having problems with an external USB 3 diskdrive, the
problems started when I moved from the 3.10.2 kernel to 3.10.3.
The machine is a ASUS M5A97 PRO, BIOS 1604.

Hi
Same problem here with 3.10.3. Dmesg filtered with 'hci'.
Each of you, please post a usbmon trace showing what happens when the
drive is plugged in.

Hi Alan
Herewith the log you requested.
The trace shows that something is sending an invalid INQUIRY command
(one with a 512-byte transfer length) to the drive. Normally such
things are done by user programs, but in this case it looks more like
the command came from somewhere in the kernel. I have no idea where.
Did you change anything besides the kernel when going from 3.10.2 to
3.10.3?
If you boot now into a 3.10.2 kernel, does the drive work?
What happens if you plug the drive into a USB-2 port? (I expect it
will make no difference at all.)

Hi Alan,
The config between 3.10.2 and 3.10.3 did not change.
The drive works correctly on 3.10.2 (I usually keep the previous kernel
available just in case).
On 3.10.3 the drive fails in a similar manner when plugged into a USB-2
port.
For interest I have tried the USB-3 drive in the USB-2 ports on an IBM
thinkpad R51 laptop that is also running 3.10.3 and that fails also.
Conversely I have tried a USB-2 drive on both the IBM and my ASUS
machine and that works fine on 3.10.3 in all available USB ports.
regards
Stuart Foster
