problems with /dev/usb/lp0


can someone help me with this problem, everything works normal with the lp0, but when i use the usb-port it won't work:
i think the problem is in here (the first part i used for the parport and that worked):
# mknod /dev/parport0 c 99 0
#AVRDUDE_PORT=/dev/parport0

AVRDUDE_PORT=/dev/usb/lp0

this is the Makefile:

AVRLIB=/export/usr/local/avrlib


TRG = lcdtest



#assembler flags
#ASFLAGS = -Wa, -gstabs

#compiler flags
#CPFLAGS = -g -Os -Wall -Wstrict-prototypes -I$(AVRLIB) -Wa,-ahlms=$(<:.c=.lst)

#linker flags
#LDFLAGS = -Wl,-Map=$(TRG).map,--cref





##### Customize the values as indicated below and :
##### make
##### make disasm
##### make stats
##### make hex
##### make writeflash
##### make gdbinit
##### or make clean
#####
##### See the http://electrons.psychogenic.com/
##### website for detailed instructions


####################################################
##### #####
##### Configuration #####
##### #####
##### Customize the values in this section for #####
##### your project. MCU, PROJECTNAME and #####
##### PRJSRC must be setup for all projects, #####
##### the remaining variables are only #####
##### relevant to those needing additional #####
##### include dirs or libraries and those #####
##### who wish to use the avrdude programmer #####
##### #####
##### See http://electrons.psychogenic.com/ #####
##### for further details. #####
##### #####
####################################################


##### Target Specific Details #####
##### Customize these for your project #####

# Name of target controller
# (e.g. 'at90s8515, atmega8', see the available avr-gcc mmcu
# options for possible values)
#MCU=at90s8515
#MCU=at90s8535
#MCU=atmega32
MCU=atmega8535

# id to use with programmer
# default: PROGRAMMER_MCU=$(MCU)
# In case the programer used, e.g avrdude, doesn't
# accept the same MCU name as avr-gcc (for example
# for ATmega8s, avr-gcc expects 'atmega8' and
# avrdude requires 'm8')
#PROGRAMMER_MCU=m32
#PROGRAMMER_MCU=8535
PROGRAMMER_MCU=m8535

# Name of our project
# (use a single word, e.g. 'myproject')
PROJECTNAME=lcdtest

# Source files
# List C/C++/Assembly source files:
# (list all files to compile, e.g. 'a.c b.cpp as.S'):
# Use .cc, .cpp or .C suffix for C++ files, use .S
# (NOT .s !!!) for assembly source code files.
PRJSRC=a2d.c timer.c buffer.c uart.c rprintf.c lcd.c lcdtest.c

# additional includes (e.g. -I/path/to/mydir)
#INC=-I/path/to/include

# libraries to link in (e.g. -lmylib)
LIBS=

# Optimization level,
# use s (size opt), 1, 2, 3 or 0 (off)
OPTLEVEL=s


##### AVR Dude 'writeflash' options #####
##### If you are using the avrdude program
##### (http://www.bsdhome.com/avrdude/) to write
##### to the MCU, you can set the following config
##### options and use 'make writeflash' to program
##### the device.


# programmer id--check the avrdude for complete list
# of available opts. These should include stk500,
# avr910, avrisp, bsd, pony and more. Set this to
# one of the valid "-c PROGRAMMER-ID" values
# described in the avrdude info page.
#
AVRDUDE_PROGRAMMERID=stk200

# port--serial or parallel port to which your
# hardware programmer is attached
#
# mknod /dev/parport0 c 99 0
#AVRDUDE_PORT=/dev/parport0

AVRDUDE_PORT=/dev/usb/lp0

##### below to use the makefile but may wish #####
##### to override a few of the flags #####
##### nonetheless #####
