I had a problem of ndisgen not recognizing the .INF file simply because of the lack of a carriage return (ASCII 13) at the end.

So I opened vi, added a carriage return at the end. Or was it the other way around?

Then I was able to generate the NDIS-wrapped kernel module for 9.2_STABLE amd64 and also 9.1_STABLE i386.

But this failed to connect to network.

This was enough to make me remove NDIS support from my config for 10-STABLE and 11-HEAD.

Good part is that I finally managed to make the wireless connection with Hiro H50191 USB adapter, chipset RSU8191SU, device rsu in FreeBSD 10-STABLE and 11-HEAD.  dhclient succeeded but slower than with a working Ethernet/wired connection.

Perhaps what went wrong previously, why I was unable to connect, was wrong software commands or failing Netgear router.

Now I use TP-Link TL-WR841N router, which I bought on my own.
