PS/2 barcode scanner shows no output, kernel 2.6 (atkbd.c)
Hi.
I tried to use a barcode scanner (Labau LS300 PS/2) under Debian 3.1 but it
failed. When using Debian's kernel 2.6.8 (2.6.8-2-686-smp) I don't get any
useful output of the scanner except of the following messages
in /var/log/kern.log.
Jul 25 08:13:45 debian kernel: atkbd.c: Keyboard on isa0060/serio0 reports too
many keys pressed.
Jul 25 08:13:46 debian kernel: input: AT Translated Set 2 keyboard on
isa0060/serio0
Jul 25 08:14:08 debian kernel: input: AT Translated Set 2 keyboard on
isa0060/serio0
Jul 25 08:14:37 debian last message repeated 2 times
A compiled Kernel 2.6.12.3 doesn't work either.
But after booting Debian's kernel 2.4.27 (2.4.27-2-686-smp) the appropriate
scan values are printed to the screen as expected.
When scanning barcodes while Linux keylogger (lkl) is running
each value is saved successfully in lkl's logfile.
If DEBUG_ATKBD is set in "/usr/src/linux/drivers/input/keyboard/atkbd.c" and I
scan a barcode I get some more output in /var/log/kern.log but nothing useful
(for me).

Seems to be a problem of kernel 2.6 in general because it works with kernel
2.4. Is there a workaround or kernel option to allow the use of ps/2 barcode
scanners with kernel 2.6?
