Hello to all !
I am the maintainer of the sane-escl backend, I have an error on an
https access on a canon XK90 scanner.
If you have an idea of why and how to bypass it, I'm interested!

     curl_handle = curl_easy_init();
     curl_easy_setopt(curl_handle, CURLOPT_URL,
"https://192.168.yyy.xxx:443/eSCL/ScannerCapabilities");
     curl_easy_setopt(curl_handle, CURLOPT_SSL_VERIFYPEER, 0L);
     curl_easy_setopt(curl_handle, CURLOPT_SSL_VERIFYHOST, 0L);
     curl_easy_setopt(curl_handle, CURLOPT_WRITEFUNCTION,
memory_callback_c);
     curl_easy_setopt(curl_handle, CURLOPT_WRITEDATA, (void *)var);
     curl_easy_setopt(curl_handle, CURLOPT_HEADERFUNCTION,
header_callback);
     curl_easy_setopt(curl_handle, CURLOPT_HEADERDATA, (void *)header);
     curl_easy_setopt(curl_handle, CURLOPT_FOLLOWLOCATION, 1L);
     curl_easy_setopt(curl_handle, CURLOPT_MAXREDIRS, 3L);
     CURLcode res = curl_easy_perform(curl_handle);
     if (res != CURLE_OK) {
           printf("respond: %s\n", curl_easy_strerror(res)); // respond:
SSL connect error
           exit--1);
     }

I don't have access to the device!

Thanks to all
Thierry
