After installing the correct drivers and checking the usb multiple times. Following the instructions for DFU mode i still get the error . I tried using “dfu-util -l” as suggest in another forum and it says cannot open DFUdevice. Any suggestions on how to proceed i need to update the firmware on the device.
!!! I was unable to detect any devices in DFU mode...
> Your device will blink yellow when in DFU mode.
> If your device is not blinking yellow, please:
1) Press and hold both the RESET/RST and MODE/SETUP buttons simultaneously.
2) Release only the RESET/RST button while continuing to hold the MODE/SETUP button.
3) Release the MODE/SETUP button once the device begins to blink yellow.

Cannot open DFU device 2b04:d00a
What driver did you download?
It’s true, Win 10 won’t need drivers for USB Serial, but for DFU it still does - so I guess you just tried the wrong drivers.
If you had the correct ones, DevMgr would not list it under Other devices with a question mark and decorate the device with an exclamation mark.
And the fact that DevMgr can display the name string does not indicate the system knows what a Photon DFU Mode is.
So I still think this statement didn’t helping the diagnosing process.
