Subject: Re: [linux-usb-devel] Please send a copy ....
Patch your kernel source and then do:
"make M=drivers/usb/storage"
and it will just build the usb-storage module (assuming you've
configured it as a module). You can then either insmod the file
(drivers/usb/storage/usb-storage.ko), or copy it to your modules tree,
and modprobe it (you'll need to rmmod it if it's already loaded).
First a couple of comments about the patch:
* the line numbers of your patch are off by about 40 lines, is this
a problem? Are my sources close enough for this? The Id line in my
source says:
* $Id: unusual_devs.h,v 1.32 2002/02/25 02:41:24 mdharm Exp $
The base tar file in the package is linux-2.6.11.tar.bz2, and there
seem to be no patches to the file in question, and here is the SRPM:
kernel-2.6.11-1.27_FC3.src.rpm.
* the patch as sent is applied only to the DB25 version of the device,
I am actually working with the HD50 version. I believe that two
changes are therefore needed.
I have appended a diff -u for the actual change that I made.
After uninstalling usb-storage.ko, replacing it with the newly rebuilt
version, modprobe'ing it, and plugging the USB device in again, the
warning messages are gone from the syslog files (see below). Looks like
success!
Now a totally different question is, how to get the Exabyte drive to
wake up the new storage device on its own (I currently have another
device in the chain that DOES wake up the new storage device when
powered up!). Oh well, that is my problem, at least everything works
once the new storage device is woken up.
Hope all this helps, please let me know if something else is needed.
Thanks, AG
