The problem appeared after Weongyo Jeong made the device, ZyXEL G-202, work in May. The device works fine for a while after being configured and then suddenly stops with "kernel: zyd0: device timeout" in /var/less/messages. A soft reboot appears not to help, the device will still not work after reboot. Cutting power will make it work again.
zyd0: <ZyDAS ZyXEL G-202, rev 2.00/48.10, addr 2> on usbus4
Just using the device for a while, eventually it will fail. A csup of ports appears to trigger the timeout quickly and reliably (haven't failed to reproduce timeout yet with 5+ tries).
