Description Mike McLean 2002-07-24 21:27:28 UTC 
* Milan-re0724.nightly
* kernel-2.4.8-7.80

In the initial insertion of the usb device everything goes well. (Well except
for an extraneous message on the console).  The module inserts, the device
works, and everything is happy.

If you unplug the device things also work as expected.  The ethernet device
disappears and life moves on.

BUT, if you then reinsert the device nothing happens (well the kernel detects
it, but the driver apparently does nothing).  No ethernet device appears.

otoh, if you rmmod pegasus before reinsertion, then things go smoothly.

see bug 69739 for details on the extraneous console messages.

The device in question is a Belkin F5D5050 USB Ethernet Adapter.

Comment 3 Mike McLean 2002-07-24 21:45:42 UTC 
I took the following actions during this syslog:

% insmod dummy   (testing something else)
% rmmod dummy
% ifdown eth0
(insert device)
% ifdown eth2 
% ifup eth2
% ping hank   (successful)
% ifdown eth2
(remove device)
% rmmod pegasus
(reinsert device)
% ping hank   (successful)
% ifdown eth2
(remove device)
(reinsert device)
% ip link list  (no eth2 visible)

How is the situation now (RHL 9 w/ 2.4.20-20.9)?
Comment 5 Pete Zaitcev 2004-04-19 18:46:46 UTC 
This was needinfo-ed since last October, Mike. I'll just close
for now then.

fwiw, this seems to be fixed in FC1.
