Description of problem:
When a Zaurus USB cradle is attached the kernel loads the CDCEther rather than
the usbnet module.

If I add CDCEther to /etc/hotplug/blacklist, then the proper module gets

It is, but I haven't got around to doing it yet. Please give me a bit of time 
to get it coded, tested, and pushed to Greg K-H.

It is actually a bug in the Zaurus code, since it is claiming to be compliant 
with the CDC Ethernet class specification, but it isn't.

Latest changes to Zaurus part of usbnet were coming from David-B
(larger send length for certain framings, and removal of private crc table).

Comment 5 ajs 2003-01-15 17:51:11 UTC
Is there a way to use /etc/hotplug/usb.handmap rather than
/etc/hotplug/blacklist  to get the proper device driver to load.  I tried that
but I couldn't get it to work.  I didn't really know what I was doing though.

Comment 6 Pete Zaitcev 2003-06-05 21:15:34 UTC
Is the 2.4.20-18.9 still broken for you?

Log messages produced by plugging in the Zaurus

The latest Red Hat kernel still loads the CDCEther module.

Attached are the log messages produced.

Comment 8 Pete Zaitcev 2004-08-20 08:17:24 UTC
Is this a problem still? If yes, what kernel version?
Also, I'll need a copy of /proc/bus/usb/devices.

Comment 9 ajs 2004-08-20 20:35:06 UTC
There is no longer quite the same problem: now neither module is
loaded.  I'm currently using kernel-2.6.8-1.521, but this has been the
behavior for a while.

Here is /proc/bus/usb/device with the Zaurus plugged in and after 'modprobe

works for me on fedora core 3 test 1 (amd64) using:


and the following initscript for usb0
(/etc/sysconfig/network-scripts/ifcfg-usb0) :

# Zaurus

configures/unconfigures correctly and loads usbnet, as far as zaurus
(5500 with ROM 3.10) is configured to use USB - TCP/IP (advanced).

Comment 13 Bugzilla owner 2004-09-30 15:40:24 UTC
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
