Description of problem:
I'm using usb networking (usbnet module) to connect
my HP iPAQ H2210 PDA (running Linux 2.6.3 with
the Familiar distribution) to my laptop:
As soon as I plug in my iPAQ, I can see that
the "usb0" network device is available:
> ifconfig -a
usb0 Link encap:Ethernet HWaddr 52:27:5E:D3:3F:A5
inet addr:192.168.0.200 Bcast:192.168.0.255 Mask:255.255.255.0
inet6 addr: fe80::5027:5eff:fed3:3fa5/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

TX packets:19 errors:4 dropped:0 overruns:0 carrier:0
RX bytes:28 (28.0 b) TX bytes:1274 (1.2 Kb)
Then, I run the below commands:
> ifconfig usb0 192.168.0.200
> route add 192.168.0.202 dev usb0
and then I can ping the iPAQ (192.168.0.202) without any problem.
This works fine with FC1, FC2 T2, but no longer works with
FC2 T3 :-(
I noticed the below error in /var/log/messages:

Here's information about my USB controllers ("lspci" output):

If other users are facing such an issue too, connecting to
another computer through USB networking, I'll be glad
to hear details! So, don't hesitate to post your comments
about this ticket.
I'll try with the latest stock kernel too...
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Connect another GNU/Linux computer with
a kernel supporting USB networking, through a USB cable.
2. Check that you have a "usbnet" network device
3. Run the ifup and route commands on both computers,
and try to ping the remote computer
This issue no longer happens with Linux 2.6.6-rc3-bk1.
I used the same config file as in the Linux 2.6.5-1.327
kernel shipped with FC2 T3.
So, this is a kernel issue, and I hope FC2 T3
will ship with a more recent kernel.
Thanks for everything that you do.
Good luck for the finish line!
Oops, I meant "FC2 Final" and not "FC2 T3"
I'll close then.
The problem is how upstream keeps a paced development...
I'm not familiar with Fedora / Red Hat's development process,
I read the bugzilla's documentation about "UPSTREAM",
but still I wonder whether it's all right to close this bug,
before a package fixing it is released.
Another issue that I see is that another
Fedora tester may encounter the same bug, will search for open
bugs about it, and will not find this entry with default
search settings, as it is closed.
Because of this, (s)he will file one more bugzilla ticket about the
What do you think?
I prefer to get dups.
Yes, strictly speaking it's premature to close. However I swim
in bugs, so I have to cull the field.
Do what's more convenient for you. I trust you...
Anyway, I'll keep an eye on this issue, as this is
something I do every day.
This no longer happens with Linux 2.6.5-1.358.
