It looks as if printer gets some amount of data but then communication 'stops' and printer waits for more data (usually I have about 2cm of page printed, paper locked and later printer error leds start blinking happily :) Not sure, if it's directly related, but system seems to be less responsive later. Version of usblp.c from 2.6.0-test2 compiled with 2.6.0-test3 does not work as I expected (I can load module, but printer is not detected - no usual 'usblp0: USB Unidirectional printer dev 3 if 0 alt 1 proto 2 vid 0x03F0 pid' message in logs). I traced my problem down to -test2-bk2 (with bk1 everything works correctly). o Printer is connected to /dev/usb/lp0; it's HP840c o ver_linux output: http://zeus.polsl.gliwice.pl/kernel/2.6.0-test3/ver_linux o config: http://zeus.polsl.gliwice.pl/kernel/2.6.0-test3/config o dmesg: http://zeus.polsl.gliwice.pl/kernel/2.6.0-test3/dmesg o /proc/bus/usb/devices: http://zeus.polsl.gliwice.pl/kernel/2.6.0-test3/devices o some related logs: http://zeus.polsl.gliwice.pl/kernel/2.6.0-test3/logs Any suggestions are welcome :) jk -- Jacek Kawa --- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.

Yes. Looks as if once/reboot (I've just checked my logs); with
-test2-bk2 and -test3.
Were you the whom I sent the diagnostic which which gave no results?
No, any problems with usblp previously. :)
Does this help?

Well, behaviour is different now - after printing those 2cm
printer doesn't wait anymore, but feeds page and then print
some garbage, which seems to be some random part of memory - once
for example something that appears to be HTTP negotiation.
No more CPU-hungry usb process, so cups could probably send
all he wanted to send...
