I just released zd1211-firmware-1.4
Get it from:
VERSION 1.4 (2007-10-04)
Sync to vendor driver v18.104.22.168
According to Atheros, this firmware fixes a USB disconnect issue which
most commonly appeared when running "lsusb" or "cat /proc/usb/devices"
while using the device.
I've given this some quick testing, can't see any problems with it.
