[sane-devel] Error in HP LaserJet M1005 Backend

[m. allan noah]

Yes- the standard says that the backend should not assume that
sane_get_devices will be called before sane_open. a better fix might
be to check for this condition, could you try this instead?

SANE_Status
sane_open (SANE_String_Const name, SANE_Handle * h)
{
  struct device_s *dev;
  int ret;

  if(!devlist_head)
    sane_get_devices(NULL,(SANE_Bool)0);

  dev = devlist_head;

  if (strlen (name))
...

if this works, and meets with the AUTHOR's approval, i will put this
in SANE CVS before release...
