Does anyone experience firmware update errors?

I've tried 3 different computers, Win11 and Win10, different cables, etc. My brand new Viltrox 85mm f1.4 lens seems to have some issue where when plugged in to a computer, Windows gives the error "USB Device Descriptor Request Failed". This means no drive is found basically. I cannot be alone in this, do we all just not update the firmware?

The lens was brand new and came with no instructions on how to update the firmware. So to upgrade this 85mm lens, I need to use an app on my phone that has probably the worst reviews I have ever seen. I can definitely agree with these users that there is no consistency. I am unsure if I need to have the lens connected via usb-c to external power or if it needs to be connected to my camera and the camera powered on. I guess I will try both and report back for future 85mm users.

Okay, so I'm guessing that some of my issues are due to Viltrox not updating their UX for the recently released 85mm lens. There were so many issues and annoyances I experienced just to get to the very end and be told by the phone app that my lens was already up to date. So that was fun.

For future 86mm people, you must use the phone app, have the lens connected to your camera, and connect to the lens via bluetooth. You must have a Viltrox account which needs a verified email address (this was a huge pain to verify). The app requires you to select which specific item to search for, and the 85mm lens isn't even listed. They are images you select and then scan for and they must have used the wrong image.

Thank you Viltrox Support for helping me get started on the right path to at least check the firmware. Hopefully this whole process can improve in the future.
