Hello Everyone! can someone help me with this problem:

I Bought an usb-to-parallel port adapter (lsusb give me Bus 001 Device 002: ID 067b:2305 Prolific Technology, Inc. PL2305 Parallel Port), and Linux recognize it as /dev/usb/lp0

dmesg:

[   35.125223] usblp0: USB Bidirectional printer dev 2 if 0 alt 1 prot
+o 2 vid 0x067B pid 0x2305
[   35.125307] usbcore: registered new interface driver usblp
[download]

now the problem: both the modules Device::ParallelPort::drv::parport and Device::ParallelPort::drv::linux that i tried in perl gave me this error for the first module:

Device::ParallelPort unabel to create driver parport (see Device::Para
+llelPort::drv::auto for further information) - Failed to load partpor
+t driver for /dev/usb/lp0 at (eval 1) line 3
 at ./parportcontroller line 5

and this for the second:

Use of uninitialized value in subroutine entry at /usr/local/lib/perl/
+5.10.0/Device/ParallelPort/drv/linux.pm line 68.
[download]

I Tried to hard code in the second module the device character file at line 68

$this->{DATA}{BASE} = linux_opendev("/dev/usb/lp0");
[download]

but this didn't work, the result is that my script doesn't set or get any bit from the parallel port. Here is my code:

#!/usr/bin/perl -w

use Device::ParallelPort;

my $port = Device::ParallelPort->new('linux');

if($port){
 print "Bit 0: ".$port->get_bit(1)."\n";
 $port->set_bit(1,  0);
 print "Bit 0: ".$port->get_bit(1)."\n";
} else {
 die "Errore sul driver\n";
}
[download]

and this is the result:

Use of uninitialized value in subroutine entry at /usr/local/lib/perl/
+5.10.0/Device/ParallelPort/drv/linux.pm line 68.
Bit 0: 1
Bit 0: 1

The Device::ParallelPort::drv::parport module give me the error above. Someone can help me? Thanks, and sorry for my bad english XD
