USB access throws Insufficient Permission error

[twzg...@gmail.com]

Hi,

I am trying to use the WebUSB to access USB devices on a Chrome browser on a Windows machine and I am getting the following error:

Failed to open device: Access denied (insufficient permissions)

Failed to open device: Operation not supported or unimplemented on this platform

Despite the USB storage device was detected:

USB device added: vendor=32902 "", product=35889 "", serial="", guid=238fe927-8b21-4f9a-90f9-15a34ea09294

How do I give permission to the USB device to allo the Chrome browser to access it on Windows ?

if the device is mass storage as you say, then WebUSB won't work by design.  for example:

I have attached a CCID smart card reader and a USB flash drive and for the flash drive it says insufficient permission which I guess I will have to use the File API.

For the CCID device, the chrome://device-log detected it as:

Driver for \\?\usb#vid_1ea8&pid_8008#00000000000001#{a5dcbf10-6530-11d2-901f-00c04fb951ed} is WUDFRd

Driver for \\?\usb#vid_1ea8&pid_8008#00000000000001#{50dd5230-ba8a-11d1-bf5d-0000f805f530} is WUDFRd

But doesn't show up when I try to use WebUSB.

Does it mean that both mass Storage and CCID are completely out of scope for WebUSB ?

last i heard, smart cards were out of scope.  for Chrome OS, there is an app already:

Last time I tested smart card access from Chrome on Windows, I had to use the workaround of installing a special USB driver.

I used this one (WARNING: This link points to a third-party application that is not affiliated with Google in any way. USE AT YOU OWN RISK) : http://zadig.akeo.ie/

But I did this testing quite a while ago, so not sure if that's relevant to the error you're seeing.

To access the ADB interface on an Android device on Windows you need to install the right driver package to tell Windows to let applications like Chrome connect to the device. Instructions for Google phones. Instructions for all other phones.
