Zyd: device timeout after a while.

[Zoltán Kéri]

Hello!

Zyd driver is not working properly under FreeBSD. After a while I get the
following error: "zyd0: device timeout".
I have to re-plug the USB WLAN stick in order to make it work again, but
the problem is, it happens often.
If I am not downloading anything, this error does not actually happen, as
far I know.

How to re-produce the bug?

1.) Plug in the USB WLAN stick and make sure your internet is working
properly.
2.) Load a few pages or download a file at an average speed.

After all that, if you want to make it work again, you have to re-plug the
USB WLAN stick.
By the way, if I am only using for example "irssi" and not downloading huge
amounts of data, this bug does not occur.
