I tried to send along an attachment that might have explained what I've
found so far. This time I'll include it inline cause it's not "REAL" long.
I've tried to
ls >/dev/ulpt0 and
ls >/dev/unlpt0 The latter because of something found in
www.apsfilter.com. in both cases the computer hung up indefinitly.
Below here is the file I tried to include on the original. note the
references to :Cuecat. it is the only other USB device I have and I used it
for reference and trial

From apsfilter.org handbook
Q: My USB-connected Epson Stylus printer won't work with {Free,Net,Open}BSD! [from the gimp-print FAQ]
A: By default, the BSD device driver for the USB printer device (usually ulpt0) does a prime, or USB bus reset, when the device is opened. This causes
the printer to reset itself (one can hear the print head moving back and forth when this happens) and lose sync. After this the printer won't go into graphics
mode and instead spews characters all over your expensive photo paper. This has been observed on the Stylus Photo 870; it likely exists with other
USB-connected Epson Stylus printers.
The fix is to use the unlpt0 device instead of ulpt0. The driver doesn't perform the USB prime when unlpt0 is opened. If this device doesn't exist on
your system you can create it with
mknod unlpt0 c 113 64 root wheel
in the /dev directory.
--------------------------------------------
dmesg:
.
ulpt0: HEWLETT-PACKARD DESKJET 656C, rev 1.10/1.10, addr 2, iclass 7/1
.
usbdevs:
% usbdevs -v
Controller /dev/usb0:
addr 1: self powered, config 1, UHCI root hub(0x0000), Intel(0x0000), rev 0x0100
port 1 addr 2: self powered, config 1, DESKJET 656C(0x2304), HEWLETT-PACKARD(0x03f0), rev 0x0110
port 2 addr 3: low speed, power 48 mA, config 1, product 0x0101(0x0101), KYE Systems Corp.(0x0458), rev 0x0100
##Here I removed the connectors then replaced it. Note the difference
between the printer and cuecat.
HP 656C Printer connector being removed from USB port:
uhub0: port error, restarting port 1
ulpt0: at uhub0 port 1 (addr 2) disconnected
ulpt0: detached
Connector re-inserted:
ulpt0: HEWLETT-PACKARD DESKJET 656C, rev 1.10/1.10, addr 2, iclass 7/1
Radio-Shack :cuecat disconnected:
uhub0: port error, restarting port 2
ukbd0: at uhub0 port 2 (addr 3) disconnected
ukbd0: detached
And re-inserted:
ukbd0: KYE Systems Corp. product 0x0101, rev 1.10/1.00, addr 3, iclass 3/1
kbd1 at ukbd0
Note the second line: kbd1 at ukbd0 , kbd1 or actually /dev/kbd1
cat /dev/kbd1 , then swiping different bar codes yields lots of data.
# ls -CF /dev/u*
/dev/ugen0 /dev/ugen0.14 /dev/ugen0.6 /dev/ulpt1* /dev/urandom
/dev/ugen0.1 /dev/ugen0.15 /dev/ugen0.7 /dev/ulpt2* /dev/usb*
/dev/ugen0.10 /dev/ugen0.2 /dev/ugen0.8 /dev/ums0 /dev/usb0*
/dev/ugen0.11 /dev/ugen0.3 /dev/ugen0.9 /dev/unlpt0*
/dev/ugen0.12 /dev/ugen0.4 /dev/uhid0 /dev/unlpt1*
/dev/ugen0.13 /dev/ugen0.5 /dev/ulpt0* /dev/unlpt2*
ls >/dev/ulpt0, ls >/dev/unlpt0 hung up the computer. I MAKEDEV'd ulpt1 &2
and unlpt1 & 2. they returned "device not configured". Back when I had a
parallel fed printer I would/could ls /dev/lpt0 or cat <file> | dos2unix
>/devlpt0 if needed. That's what I've tried to do to discover the device
name of my usb printer to no avail/
I hope this is better explanation of what I've tried.
