Webusb扫描文件 [英] Webusb to scan documents
本文介绍了Webusb扫描文件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
有人成功配置了webusb来扫描文档？我能够连接到USB扫描仪，但无法找到任何关于扫描文档的命令的文档：

自动驱动
下面的代码测试低级别的传输，但即使PromiseStatus标记为已解决，状态仍然失效，device.transferIn状态保留悬而未决。我无法继续前进，因为我没有找到任何有关我的扫描仪或任何其他扫描仪的文档。
navigator。 usb.requestDevice（{filters：[{vendorId：0x1083}]}）
.then（selectedDevice => {
device = selectedDevice;
return device.open（）; // Begin （（）=> device.selectConfiguration（1））
.then（（）=> device.claimInterface（0））
.then（（）=> device.controlTransferOut（{
requestType：'vendor'，
recipient：'device'，
request：0x22，
value：0x01，
index：0x01}））
.then（（）=> device.transferIn（1,64））//等待来自端点＃1的64个字节的数据。
.then（result => {
let decoder = new TextDecoder（）;
console.log（'Received：'+ decoder.decode（result.data））;
}）
.catch（error => {console.log（error）;}）;
谢谢！
解决方案
<当启用plustek驱动程序的调试日志时，以下是一些更多的调试输出：
<$ c $ 我试图通过WebUSB扫描CanoScan LiDE 25，它使用plustek芯片。 c> // http://www.linux-usb.org/usb.ids
// 04a9 Canon，Inc.
// 2200 CanoScan LiDE 25
navigator.usb.requestDevice（ （过滤器：[{vendorId：0x04a9}]}）
.then（device => {
console.log（device.productName）; //CanonScan
console.log device.manufacturerName）; //Canon
}）
.catch（error => {console.log（error）;}）;
我目前尝试使用wireshark和USBMon对协议进行逆向工程。理智家伙已经做到了这一点（
在上图中，您可以看到Wireshark和命令的追踪：
export SANE_DEBUG_DLL = 255＃已启用调试日志记录为
scanimage -p --resolution 150 --mode Gray -x 210 -y 297> image.pnm
这并不能回答你的问题。尽管如此，它仍然显示出前进的方向。
我希望最具创新性的东西是用emscripten（ https://github.com/kripken/emscripten ）转换为javascript，然后直接使用它。
<当启用plustek驱动程序的调试日志时，以下是一些更多的调试输出：
$ export SANE_DEBUG_PLUSTEK = 12
$ scanimage -L
[sanei_debug]将dll的调试级别设置为0.
[sanei_debug]将plustek的调试级别设置为12.

The code below test a low level transfer, however even the PromiseStatus is marked as resolved, status is stall and device.transferIn status remain pending. I wasn't able to go further as I didn't find any documentation for my scanner or any other scanner.
navigator.usb.requestDevice({ filters: [{ vendorId: 0x1083 }] })
.then(selectedDevice => {
device = selectedDevice;
return device.open(); // Begin a session.
})
.then(() => device.selectConfiguration(1))
.then(() => device.claimInterface(0))
.then(() => device.controlTransferOut({
requestType: 'vendor',
recipient: 'device',
request: 0x22,
value: 0x01,
index: 0x01}))
.then(() => device.transferIn(1, 64)) // Waiting for 64 bytes of data from endpoint #1.
.then(result => {
let decoder = new TextDecoder();
console.log('Received: ' + decoder.decode(result.data));
})
.catch(error => { console.log(error); });
Thank you !

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.pnm
This 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:
$ export SANE_DEBUG_PLUSTEK=12
$ scanimage -L
[sanei_debug] Setting debug level of dll to 0.
[sanei_debug] Setting debug level of plustek to 12.
