[gentoo-user] strange dmesg output

[gentoo-user] strange dmesg output

[Maxim Wexler]

Hi group,

Still sorting out the glitches in the new 2.6.30-r7 kernel.

eg the strange output of dmesg:

...

usb-storage: Bulk Command S 0x43425355 T 0x8 L 0 F 0 Trg 0 LUN 0 CL 6

usb-storage: Status code 0; transferred 18/18
usb-storage: -- transfer complete
usb-storage: Bulk data transfer result 0x0
usb-storage: Attempting to get CSW...
...

and so on, for 2739 lines. Nothing about other drives, file sytems,
hardware, busses etc. When I plug in a usb key, for instance, dmesg
doesn't even notice although the log console(F12) makes a note of the
device. The earlier kernel acts "normally".

Did I leave something out of the kernel? I can't think what.

It looks like you have USB debug turned on. I remember there was a
kernel that was released that had that. Normally it's off, but you
should turn it off if it's on.

Maybe you pulled in too much :-)

It could be some debug flag switched on in the USB storage subsystem.

#CONFIG_USB_DEBUG is not set

I'm not aware of such a "subsystem". Can you give an example?

[edit]

CONFIG_USB_STORAGE_DEBUG = y

I turned it off, recompiled, copied the kernel over and rebooted.
$dmesg still displays the verbose 'usb-storage' lines and excludes
everything else

here's a long thread on this same subject

https://lists.one-eyed-alien.net/pipermail/usb-storage/2008-November/004121.html

I don't think he found a solution either.

The good news, the system can now see the soundcard. Before I had to
run alsaconf at every boot.  Is there a connection?

It's a generic term applied to coherent chunks of the kernel.

The whole kernel is one large system.
The part (usually with a single maintainer) that deals with USB storage is a 
sub-system
