This variable, if set, overrides all devices, manually configured
in the log files and disables auto discovery.
Examples:
SANE_AIRSCAN_DEVICE="escl:Kyocera eSCL:http://192.168.1.102:9095/eSCL"
SANE_AIRSCAN_DEVICE="wsd:Kyocera WSD:http://192.168.1.102:5358/WSDScanner"
Formal syntax:
"PROTO:DEVICE NAME:URL"
Where:
- PROTO` is either `escl` or `wsd`.
- DEVICE NAME will appear in the list of devices.
- URL is the device URL, using `http:` or `https:` schemes.
The primary purpose of this variable is the automated testing
of the `sane-airscan` backend.
