I'm trying to build a driver for the Startech USB31000SW. A linux driver is included but it has to be compiled and installed. When running make I get the following errors:

make -C /lib/modules/3.2.0-52-generic-pae/build SUBDIRS=/home/lars/Hämtningar/usbnet/Linux/Kernel 2.6.x_3.x modules

make[1]: Går till katalogen "/usr/src/linux-headers-3.2.0-52-generic-pae"

make[1]: *** Ingen regel för att skapa målet "2.6.x_3.x".  Stannar. 

make[1]: Lämnar katalogen "/usr/src/linux-headers-3.2.0-52-generic-pae"

make: *** [default] Error 2

The third line translates to: No rule to create target

According to the read me file, the kernel source is needed, so I installed it from Synaptic.

This is the makefile:

CURRENT = $(shell uname -r)

TARGET  = ax88179_178a

OBJS    = ax88179_178a.o

MDIR    = drivers/net/usb

KDIR    = /lib/modules/$(CURRENT)/build

SUBLEVEL= $(shell uname -r | cut -d '.' -f 3 | cut -d '.' -f 1 | cut -d '-' -f 1 | cut -d '_' -f 1)

USBNET  = $(shell find $(KDIR)/include/linux/usb/* -name usbnet.h)



ifneq (,$(filter $(SUBLEVEL),14 15 16 17 18 19 20 21))

MDIR = drivers/usb/net

#USBNET = $(shell find $(KDIR)/$(MDIR)/* -name usbnet.h)

endif



#ifneq (,$(filter $(SUBLEVEL),21 22 23 24))

#USBNET = $(shell find $(KDIR)/$(MDIR)/* -name usbnet.h)

#endif



#$(if $(USBNET),,$(error $(KDIR)/$(MDIR)/usbnet.h not found. please refer to readme file for the detailed description))



EXTRA_CFLAGS = -DEXPORT_SYMTAB

PWD = $(shell pwd)

DEST = /lib/modules/$(CURRENT)/kernel/$(MDIR)



obj-m      := $(TARGET).o



default:

    make -C $(KDIR) SUBDIRS=$(PWD) modules



$(TARGET).o: $(OBJS)

    $(LD) $(LD_RFLAG) -r -o $@ $(OBJS)

pw

install:

    su -c "cp -v $(TARGET).ko $(DEST) && /sbin/depmod -a"



clean:

    $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) clean



.PHONY: modules clean



-include $(KDIR)/Rules.make

Any ideas would be welcome
