Yet another WUSB600N problem

[TheConsaw]

hi guys, sorry for yet another n00b thread on the infamous wusb600n, i have tried to follow other threads instructions but i get lost, novice here

so i have downloaded the RT3572 driver from railink and put it in my home folder
executed the following then:

bunzip2 2009_1222_RT3572_LinuxSTA_V2.3.0.0.tar.bz2

tar -xvf 2009_1222_RT3572_LinuxSTA_V2.3.0.0.tar

no problems here

I have modified the 2 files as instructed:

4) add the device and vendor id "{USB_DEVICE(0x1737,0x0079)}" between the "#ifdef RT35xx" and "#endif // RT35xx //" in the file "common/rtusb_dev_id.c"
5) modify the "os/linux/config.mk" like I described in my previous message

no problems here

next step according to all instructions :
sudo make and
sudo make install, trips me up, i get "no targets specified and no makefile found"

probably a basic mistake somewhere here, but my knowledge of the command line is zilch

thanks in advance
