Well, I cannot finish printing anything now and I believe, that one of above is responsible. 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 :)
