The address looks OK to me. I do not know why it bounced.

My involvement with the RTL8187 devices only started with 2.6.X, where X is 25
or 26. I have no knowledge of the driver in kernel 2.4.

There have been various complaints about the driver, particularly on RTL8187L
hardware, that concern rate setting using the minstrel algorithm. I have been
unable to reproduce the results.

Please answer the following questions;

Does the device work is you lock the rate at 1 Mbps?

What is the USB ID as shown by lsusb?

Does it work when you use the PID rate-setting algorithm? To enable this, you
will need to set CONFIG_EXPERT=y.
