  I just got a 1240U and was very very happy when everything seemed to work. Then the other
  shoe dropped...

  It turns out that when I set the scan resolution to 800 or higher in xsane I get a message
  "Error during read: invalid argument" and
  [epson] error in receive - status=5.
  I have been using the TPU (I'm not sure that matters).

  Meanwhile the kernel reports
  read_scanner(0):funky result - -32. Please notify the maintainer.

  I have to kill xsane, and afterward it is unable to find any devices. Then
  kernel talks about NAK received. The only way to restore order seems to be to completely
  remove the usb stack (just scanner doesn't work) and insmod everything again.

  Just to make clear everything works perfectly below at 600 dpi and lower!

  I'm using a sane rpm from helix gnome that contains epson backend 0.1.33.
  The kernel is a Mandrake 2.2.17 (i.e. backport), and I got a number of other USB devices
  that work just fine (Phillips web cam, pegasus ethernet, and Epson Photo printer).

  I will of course try a more modern backend. I also saw on the FAQ the NAK
  timeout, but I'm not sure that's the problem since it only happens after things are
  screwed.

  I was wondering whether anyone has reported this type of thing. I'll let you know what the
  more modern backend does.
