[9fans] usb or lp

[Sergey Reva]

Hello 9fans,

With "latest sources" (about month ago) I can't print on my Canon S200 printer with USB
interface. What happened? How fix this?

/sys/src/cmd/usb/misc/usbprint have error:

for (c in '{seq 16})
where $c used in usb$c, it only generate number from 1 to 16, how about usb0?

In my old sources I have usbprint like this:
for (c in /dev/usb?[0-9]*)
But I don't used this and printer works well.

No when I try print something I get only this:
cat: write error copying /tmp/xyz: ken has left the building

And finally in usbprint all version for printing used ep2data but in my
case work only ep1data.

With best regards Sergey Reva

I feel somthing is wrong in your usb printer setting...
Yes, usb device driver was changed, however, for printers
I think there is no difference.

I don't know what type of printer of Canon S200, however,
do you have correct entry in /sys/lib/lp/devices and neccessary 
initializer for that printer?

>No when I try print something I get only this:

I think this means you have not binded safely /n/lp to the correct
usb printer device.


1) search the /dev/usb tree, and find the strings of '0x020107',
which is the usb printer.   And then, 
echo 'ep 3 bulk w 64 32' > /dev/usb3/$i/ctl
where ep '3" is the endpoint number of USB printer's data endpoint,
and $i stands for the usb device number found.
Then, bind /dev/usb3/$i/ep3data /n/lp, and then print the data
to /n/lp.

Re: [9fans] usb or lp

[Russ Cox]

if the seq is causing problems that using for(c in /dev/usb?[0-9]*)
solves, then i would just use the good for loop instead and we 
can put it back.  or at least change it to 

for(c in /dev/usb^`{seq 0 16}) 

instead of

for(c in /dev/usb/^`{seq 16})

if not having usb0 is really the problem.  it's hard to tell
what you're saying the problem is.

Here is my /sys/lib/lp/device, it's equal to my old (working) installation:

canon - - /dev/usb0/1/ep1data - gs!bjc600+nohead generic nospool - - - -

Yes, usbprint do the same but this don't work in all version of Plan 9 which I have.
In my case writing endpoint is 1, I see it when run usb/usbd -v -d.
I have only 2 endpoints. When I try bind (in old or new) I get this:

term% bind /dev/usb0/1/ep1data /n/lp
bind ep1data /n/lp: inconsistent mount

Binding ep2data take same result.

Any ideas.

Sergey

After echo -n 'ep 1 bulk w 64 32' >/dev/usb0/1/ctl ?

No, sorry.

In my HP psc2550, working version is as follows:

 8 0x00d4ff          0 bytes          0 blocks
term% 

In this case the above 3 0x020107 is for data output endpoint.
I hope this may help you...

Add me, too.
Thanks for your help to my understanding of WinXP world.
I felt it's the world for money though.☺

>> bind ep1data /n/lp: inconsistent mount

mntgen creates /n/xxx files on demand.  If you try to bind to /n/xxx,
mntgen will create a directory to bind to (in the mntgen file system).
ep1data is not a directory but a file, so the bind fails.  Create the
(empty) file /n/lp by hand.

I fixed the problem on sources by moving /n/lp to /dev/lp and
updating usb/usbprint and the man page.  You don't have to create
a bind point in /dev.  usb/usbprint does that for you.

If you use usbprint, you probably need to adjust your /sys/lib/lp/devices.

Re: [9fans] usb or lp

Hello 9fans,

I find problem!

New usb driver not configure file epXdata for writing or inputing, old
driver do this. Why this happen?

When I run usb/usbd -v -d I can see this:

.... maxpkt 64 interval 0ms [OUT] [Bulk]                       #usbd know about direction on this endpoint
.... maxpkt 64 interval 0ms [IN] [Bulk]

But when I ls -l /dev/usb0/1 I get this:

--r--r--r U 0 rlab rlab 0 Sep 13 22:55 /dev/usb0/1/ep1data     #but not set direction for files
--r--r--r U 0 rlab rlab 0 Sep 13 22:55 /dev/usb0/1/ep2data

In old installation this looks like:
---w--w--w- U 0 rlab rlab 0 Sep 13 22:55 /dev/usb0/1/ep1data
--r--r--r-- U 0 rlab rlab 0 Sep 13 22:55 /dev/usb0/1/ep2data

When I set direction manually all works well:
echo -n 'ep 1 bulk w 64 32' >/dev/usb0/1/ctl

Thanks for help!
Sergey

I saw that too yesterday.  I'll look into it tonight.  Hopefully you'll have
an update tomorrow.

This is not really a problem because you have to send a string like
	ep 1 bulk w 64 32
to the control device before you can use the endpoint anyway.

I fixed a problem in usbaudio related to checking maxpkt.  There's an update on
sources.
