[sane-devel] problem with UMAX 2000P scanner

[aneesh m raj]

Hi ,
Thank u it worked the mode was in ECP+EPP . Im using a program to detect scanner devices but I cant retrieve the device by calling sane_get_devices() function .The 
SANE_Device structure is NULL.


%%%%%%%%%%%%scanner.h%%%%%%%

#include <sane/sane.h>
#define SANE_MAX_USERNAME_LEN 128
#define SANE_MAX_PASSWORD_LEN 128
typedef void (*SANE_Authorization_Callback)
      (SANE_String_Const resource,
       SANE_Char username[SANE_MAX_USERNAME_LEN],
       SANE_Char password[SANE_MAX_PASSWORD_LEN]);
SANE_Status initialize_scanner(SANE_Int* version,SANE_Authorization_Callback callback);
void exit_scanner(void);
SANE_Status get_scanners(const SANE_Device*** device, SANE_Bool local);

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
//scanner.c

#include <stdio.h>
#include "scanner.h"

int main()
{
  SANE_Status status= 0; 
  const SANE_Device** dev;
  int i = 0;
  status = initialize_scanner(NULL,NULL);
  if(status != SANE_STATUS_GOOD)
  {
  printf("Scanner not properly initialized...\nExit code: %d\n",status);
  exit(0);

  }
  else
  { 
        status = get_scanners(&dev,1);
        if(status == SANE_STATUS_GOOD)
          { 
            /*
            dev[i] is NULL
            */
            while(dev[i] != NULL)
                {
                   printf("Name - %s\n", ((const SANE_Device*)dev[i])->name);
                    printf("Vendor - %s\n",((const SANE_Device*)dev[i])->vendor);
                    printf("Model - %s\n",((const SANE_Device*)dev[i])->model);
                    printf("Type - %s\n\n",((const SANE_Device*)dev[i])->type);
                    i++;
                }
           }

         
  }
  exit_scanner();  
  return 0;
}

SANE_Status initialize_scanner(SANE_Int* version,SANE_Authorization_Callback callback)
{
  return sane_init (version,callback);

}

void exit_scanner(void)
{

  sane_exit();

}


SANE_Status get_scanners(const SANE_Device*** device, SANE_Bool local)
{
  
  return  sane_get_devices (device,local);

}

Thanks in advance
Aneesh

  Hi ,
  Im using a UMAX 2000P parallel port printer and I have downloaded SANE and the patch for UMAX, when I run the umax_pp tool I receive a message "No scanner found Status 134 not expected" .Im using debian linux kernel 2.2.20. Any help is appreciated.
  Regards
  Aneesh
