Subject: uas: module not loaded automatically

Hi,

my Delock external USB drive stopped working after updating from a
UAS-disabled distro kernel to latest 3.17-rc7 with UAS on. That UAS was
key became clear to me only after looking at storage_probe(): the device
is ignored by usb-storage if it is UAS-capable. However, nothing causes
uas.ko to be loaded when the drive is plugged here. How is this supposed
to work in the normal case?

lsusb of the device below.

Is the uas.ko module installed, and was depmod run after installing it ?

uas.c has the following:

{ USB_INTERFACE_INFO(USB_CLASS_MASS_STORAGE, USB_SC_SCSI, USB_PR_BULK) },
{ USB_INTERFACE_INFO(USB_CLASS_MASS_STORAGE, USB_SC_SCSI, USB_PR_UAS) },

Which should make it load automatically on your device.

Hans

Definitely. Just retried after another depmod -a, and only modprobe uas
made it work.

Should this match with what lsusb -v reports for the device? I have no
reference to a device with working UAS-probe.

Yes, and it does, for both alt settings of your device:

bInterfaceClass 8 Mass Storage
bInterfaceSubClass 6 SCSI
bInterfaceProtocol 80 Bulk-Only

bInterfaceClass 8 Mass Storage
bInterfaceSubClass 6 SCSI
bInterfaceProtocol 98

Where 98 == USB_PR_UAS, seems you have an quite old lsusb if it does not
know that though. Could it be the rest of your userspace is old too, and is
not smart enough to load all matching drivers, instead only loading the first matching
driver (which happens to be usb-storage) ?

Hans

It says "007".

OpenSUSE 13.1, all updates installed. Which components are involved?
udev - Version 208? Below is the udevadm monitor output.

Hmm, that is not all that old, I would expect that to work.

Here is how things "work" on my system:

[hans@shalem ~]$ lsmod | grep uas
uas 22414 0
usb_storage 65065 1 uas
[hans@shalem ~]$ sudo rmmod uas
[hans@shalem ~]$ lsmod | grep uas
[hans@shalem ~]$ sudo modprobe usb:v174Cp5136d0100dc00dsc00dp00ic08isc06ip50in00
[hans@shalem ~]$ lsmod | grep uas
uas 22414 0
usb_storage 65065 1 uas

So as you can see the modalias taken from your udev debug output causes
uas to get loaded, can you try the above ?

Also what does "modinfo uas" say? For me it says:

[hans@shalem ~]$ modinfo uas

sig_hashalgo: sha256

Note the alias-es with vendor and product ids are from quirks, and your version
will likely not have these. But the first 2 generic ones should be there, and
match the modalias from the udev output.

Maybe, first lets try to pinpoint the cause a bit better.

That command sequence doesn't cause uas to be reloaded. Anything I need
to customize for my setup?

Not that I know of, so this seems to be a modprobe issue, and this should
probably be taken to the relevant list for modprobe. Please put me in the CC
when you send a mail there, and you likely will want to include the output
of the above commands + the modinfo output for both uas and usb-storage.

That looks good, so no idea why modprobe is not loading it.
