Driver rtl8187 should work for this device.

AFAIK, that has never worked.

Your device has the USB ID 0bda:8189. That is built into the device. You cannot
force it to be anything else.

It appears that you are not using NetworkManager. If that is true, then I think
you should be preparing the correct ifcfg file for whatever distro you are
using. The hexadecimal key for WEP should be there. A passphrase almost never
works there. If you want to use WPA or WPA2, then you can use a phrase; however,
you will need to install wpa_supplicant and the appropriate configuration file.

To test is your device is working, get rid of ndiswrapper, allow rtl8187 to
load, and (as root) run the command 'iwlist scan'. If you can see your AP, then
the device is likely OK.

You should pick one of the distros you mention, and post a request for wireless
configuration on their help forum. I do not use any of them, and I'm not
familiar with their specific configuration.

I also recommend using NetworkManager. It makes wireless setup much easier.
