Thread: USB to Parallel Driver Problem

usb parallel driver problem
wish u happy new year!!!!!!

purchased usb parallel port cable ( supports ieee1284 standard).this cable plug , play cable. install usb printing support @ device manager in windows 7.

is there way or driver install parallel port in computer linux enviorenment?

because need use cable jtag programmer. dont have parallel port on laptop.if able install usb parallel cable(which support ieee1284) true parallel port jtag software support jtag programmer.

did lots of things regarding work. dear experts please me resolve this.im in sereous issue on problem.thank verymuch. , have nice time.

while i've used 1 usb parallel cable, (cables go....i believe),
worked out of box on parallel printer. think yours do
same.

try in terminal see it's recognized:

code:

dmesg | tail

then plug in usb parallel cable , do:

code:

dmesg | tail sudo lshw -c usb lsusb

for more detailed information.

example, i've ran command , plugged in usb serial
adapter , get:

code:

larry@debian:~$ lsusb bus 002 device 004: id 046d:c408 logitech, inc. marble mouse (4-button) bus 002 device 002: id 8087:0020 intel corp. integrated rate matching hub bus 002 device 001: id 1d6b:0002 linux foundation 2.0 root hub bus 001 device 003: id 13d3:5130 imc networks  bus 001 device 002: id 8087:0020 intel corp. integrated rate matching hub bus 001 device 001: id 1d6b:0002 linux foundation 2.0 root hub larry@debian:~$ lsusb bus 002 device 007: id 058f:9720 alcor micro corp. usb-serial adapter bus 002 device 006: id 046d:c408 logitech, inc. marble mouse (4-button) bus 002 device 002: id 8087:0020 intel corp. integrated rate matching hub bus 002 device 001: id 1d6b:0002 linux foundation 2.0 root hub bus 001 device 003: id 13d3:5130 imc networks  bus 001 device 002: id 8087:0020 intel corp. integrated rate matching hub bus 001 device 001: id 1d6b:0002 linux foundation 2.0 root hub larry@debian:~$

now can more information adding couple of options lsusb,
adding vendor : product information 058f:9720.

code:

lsusb -v -d 058f:9720

if software writing parallel port may need create
symbolic link usb device software's output routed
through usb parallel port. real parallel port in *nix typically
/dev/lp0 or /dev/lp1 device. (the usb serial adapter typically are
/dev/ttyacmo or /dev/ttyusb0, i've never looked usb parallel
cable.)

i've listed "ls -alt /dev/u*" devices on desktop usb parallel cable:

larry@lk-ubuntu:~$ ls -alt /dev/u*
lrwxrwxrwx 1 root root 7 2012-01-03 14:15 /dev/usblp0 -> usb/lp0
lrwxrwxrwx 1 root root 7 2012-01-03 10:29 /dev/usblp1 -> usb/lp1

and links shown.......

i've done type of thing serial port , works great!

appears in bit of reading..............
