It looks like ndiswrapper doesn't like the Windows driver that you loaded into it. Sometimes this happens. First, remove the Windows driver that you have currently installed:
Then install a better driver. According to the ndiswrapper site, these are links to ones that should work for your card:
sudo ndiswrapper -r net8187b
