[9fans] usb/print problem since last update

[Akshat Kumar]

Last time I played with printing, was quite a while
before the last update to usb/print (apparently Sep.
25). And stuff worked back then.

Here's the output now:

cpu% usb/print
usb/print: startdevs: opening #0 /dev/usb/ep7.0
usb/print: /dev/usb/ep7.0: config: d2h data too large to fit in uhci
usb/print: no device found

and what does the ctl see?

cpu% cat /dev/usb/ep7.0/ctl
enabled control rw speed full maxpkt 8 pollival 0 samplesz 0 hz 0 hub
4 port 1 idle
255 csp 0x00ccff csp 0x020107 csp 0x00d4ff vid 0x03f0 did 0x4f11 HP
'Officejet 5600 series'

Using the backup, usb/_print from July 28, stuff still
works (there's a usable /dev/lp^$n device for printing
and no error).

Have you updated your kernel?

We increased the size of the max ctl request in both the usb
library and also in usb[ueo]hci.c

You seem to have a new library but an old kernel. The library
is asking for more max size than the kernel can afford now.

I'm sorry, I should have teached the kernel how to cope with
old sizes. In the mean time, it's easier if you recompile your kernel.

I haven't updated the kernels. Will do.

Furrthamoa...
With the old usb/print (and the old kernel stuff), I get this
each time I try to print:

cat: write error copying /tmp/pdf178624: request timed out

and there seems to be no way of shaking it.
Was this perhaps addressed in the latest kernel and tool
updates?


Thanks,
ak

I think it should.
But let me know if the problem persists.

thanks

I haven't been able to test printing yet, but with
the new Kernel and tools, my terminal needs to
be rebooted each time I disconnect and reconnect
the printer USB (or turn printer on/off, of course).
usb/print otherwise just says "no devices found".
On the other hand, regardless of however many
reboots I do, and when I plug in the printer,
usb/print *never* finds the printer on my CPU
server. I'm not sure if it has to do with the
different kernels or what... just have noticed this
distinction. Prior to these updates, I could unplug
and replug the printer without any hassle.

usbd is in the boot section of each kernel

Please, enable debug and send me the output
off-list.

thanks

It turns out, the problem was just a shoddy
USB port. Using another one, printer works
fine. Also, the old timeout bug is no longer
there.

Thanks for your fine work and all the tasty
fish, Francisco.
