Correct driver for USR5410-g pcmcia card

[Beeblebrox]

I have searched through the ubuntu forums for the correct driver for this and since the card is pcmcia, i have done the requisite fiddleing with "yenta_socket.ko" without result.

The chip in the card is supposedly a Tx Instr, and I keep coming up with posts that the correct driver for this is the "acx100". Under ubuntu you are to install "ubuntu-restricted-drivers" to get acx, but BT does not have this pkg in the repository.

My option then is to build acx from source. I just want to know if there is any problem with "make install" from source in BT (I don't see why there would be...)

1. Bad news for ACX100 - From the wiki:
The ACX driver has WEP support, but not WPA

2. USR home page for the device advises driver from www.linuxant.com, which as I understand kind of works like ndiswrapper. However - more importantly - the driver requires a license fee / year. Back to ACX...

3. I forgot to mention that BT does not even recognize the device (pcmcia) so not sure if the issue is the driver for the chip inside (TI-ACX111). Anyway, now I am trying to build ACX from source (requires Linux Headers - installed) with below command but get this error:

sudo make -C /lib/modules/`uname -r`/extra M=`pwd`
make -C /lib/modules/2.6.39.4/build SUBDIRS=`pwd` modules
make[1]: Entering directory `/lib/modules/2.6.39.4/build'
make[1]: *** No rule to make target `modules'. Stop.
make[1]: Leaving directory `/lib/modules/2.6.39.4/build'
make: *** [acx.o] Error 2

I assume BT has a different target setup than ubuntu? How to get the build?
