Me again. I still have a problem. I have modified usbDevices vendorId and productId of permisssions in manifest.json. But it can not enumerate my device all the same, please help me out.

Is your device a hid device or a usb device?

Is your device a U2F device?

No. Image that if it's a u2f device, after i added "u2fDevices" permission in permisssions of manifest.json, it was supposed to work.

Am i right?

Is the extension written by yourself? Or use the open source extension https://github.com/google/u2f-ref-code ?

I used the open source extension.

Here is part of code from usbgnubbydevice.js



From the code, you can get that the usb device in this extension works only for Yubico device. So you need to modify vendorId and productId according to to your own device.

Note:
The extension is sure to call API chrome.usb.getDevices() to enumerate usb device. Thus you can check palce where uses this API to find out the problem.

Code: Select all

/**

 UsbGnubbyDevice.WINUSB_VID_PIDS = [
       {'vendorId': 4176, 'productId': 529}  // Yubico WinUSB
            ];

Aha, it works, it works.. Thank you very much for your help.

Command format that the extension sends is not inconsistent with my product command format. I may need to implement it by myself.
