Umax 1220P scanner not detected

[hazel]

I am trying to get my scanner to work in what is basically a customised Slackware installation. The scanner worked under Debian Wheezy (kernel 3.0, sane 1.0.14).

I am now using a 2.6.37 kernel and sane 1.0.22. My parallel port is set to EPP (which is what this particular backend requires) and is correctly identified by the kernel:
parport0: PC-style at 0x378, irq 7 [PCSPP,TRISTATE,EPP]
The parport and ppdev modules are loaded automatically.

Here are the relevant kernel configuration flags:

CONFIG_PARPORT=m
CONFIG_PARPORT_PC=m
# CONFIG_PARPORT_SERIAL is not set
CONFIG_PARPORT_PC_FIFO=y
CONFIG_PARPORT_PC_SUPERIO=y
# CONFIG_PARPORT_GSC is not set
# CONFIG_PARPORT_AX88796 is not set
CONFIG_PARPORT_1284=y
CONFIG_PNP=y
CONFIG_PNP_DEBUG_MESSAGES=y

When I run scanimage -L as root with SANE_DEBUG_UMAX_PP set to 5 and SANE_DEBUG_UMAX_PP_LOW at 255, I get the attached error log.

Can anyone guide me as to what to do next?

I have egg on my face! It turned out to be a bad connector. I discovered today that my printer wasn't working either; cups thought it was printing but nothing actually got through. So I went over the whole parallel connector train and pushed all four of them in hard. After that the printer worked again and I suddenly realised that that might be what had stopped the scanner from being detected. So I tried again and this time it worked.

I can scan now - at least as root and with text originals. Pictures are lousy but there's plenty of time to fix that. I don't have much use for picture input anyway.

Thanks for returning with the solution, hazel... sooner or later, this will probably get someone else out of the same pickle.

Glad you are up and running again!
