I followed this guide:

but I am getting an error "No DFU device was connected" during Realsense 435 Firmware Upgrade for Windows 10. I'm not sure how to resolve this.. Thanks

Would it be possible to open the RealSense Viewer program with your camera and see what name your D435 is described as? If it says 'Intel RealSense USB2' then that would indicate that the camera is being treated as though it is plugged into a USB 2.0 port, even if it is in a USB 3.0 port. This mode can severely limit the camera's functionality.
The USB2 issue is on Intel's list of planned fixes to address in a future firmware update. Other than doing repeated plug-unplugs like I suggested (Intel recommend trying different insertion speeds), you could try inserting the camera into the computer's USB port and then plug-unplugging the opposite end of the cable (the one that goes into the side of the camera).
FWIW - there seem to also be some legacy USB3.0 ports that report as being USB3.0 in the realsense viewer
- but which are still being treated like a USB 2.0 connected device.
On one of these systems we found that an "ASMedia USB3.0 eXtensible Host Controller" with an old driver was causing regular crashes.
It may be worth checking that all your usb related devices are running the latest drivers and patches.

Hi
I faced same problem.
I used USB 3.0 port Hardware ("SS" mark Printed) but Camera recognized as USB 2.0.
solution is simple.
1:Run "Intel.RealSense.Viewer.exe".
2:Click "More -> Hardware reset"
(below image is already USB3.0 recognized)
3:USB 3.0 recognized.
This way is reliable compared to Plug and Unplug camera many times.
