I am running Chrome's WebUSB on Windows 7 to try and open a SmartCard reader. When I use navigator.usb.requestDevices() with no filter on, the device appears sometimes. If I include the vendorId and the productId in the filters, then the device isn't selectable/listed In Chrome. Additionally, when I try to operate the device with
.then(() => device.selectConfiguration(1))
.then(() => device.claimInterface(0))
I get access denied (insufficient permissions). In practice, is each device really required to have a device descriptor formatted exactly like the one posted on the WebUSB documentation in order to connect the device to Chrome and operate it? I've also tried changing the drivers to WinUSB using Zadig, but that didn't change anything.
