Webusb to scan documents
Anybody had successfully configured webusb to scan a document ? I am able to connect to the usb scanner but wasn\'t able to find any documentation on commands to scan docume
-
I am trying to get scanning over WebUSB working with a CanoScan LiDE 25. It uses a plustek chip.
// http://www.linux-usb.org/usb.ids // 04a9 Canon, Inc. // 2200 CanoScan LiDE 25 navigator.usb.requestDevice({ filters: [{ vendorId: 0x04a9 }] }) .then(device => { console.log(device.productName); // "CanonScan" console.log(device.manufacturerName); // "Canon" }) .catch(error => { console.log(error); });I currently try to reverse engineer the protocol with wireshark and USBMon. The guys from sane already did that (https://gitlab.com/sane-project/backends/blob/master/backend/plustek.c)
In the picture above you can see a trace with Wireshark and the command:
export SANE_DEBUG_DLL=255 # enabled debug logging for sane scanimage -p --resolution 150 --mode Gray -x 210 -y 297 > image.pnmThis does not answer your question. Nevertheless it shows the way to go.
I would expect that the most innovate thing would be to compile sane with emscripten (https://github.com/kripken/emscripten) into javascript and then directly use it.
Here is some more debugging output, when enabling the debugging log of the plustek driver:
