How to Fix Betaflight USB Connection Errors ⭐

Since I literally get this question EVERY day, I might as well make a video about how I get around this problem. Note, this is what works for ME. Yes, there are other ways to fix this problem like with many things, more than one way to tackle a problem...
Here are the links to the two tools I mentioned...
🚩 Zadig - zadig.akeo.ie/
🚩 impulseRC driver fixer - impulserc.com/pages/downloads
⭐ Note, you may also need to re-install the STM32 USB drivers

6 years later and still works! thank you so much man!!

I HATE DRIVERS. LITERALLY THE MOST STRESSFUL PART OF THIS HOBBY.

The only thing worse are student drivers

Everyones new at some point

[@JesusNOTreLIEgion]

@@TheBoatPirate 7 months later and the joke is STILL going over your head LOL. No offense just found this funny. Hope all is well brother

[@GrumblyAirMonk]

agreed. im about to give up opn this hobby becauise of betaflight

[@BULLETENVY]

@@GrumblyAirMonk don't do it dude. Its the most amazing (expensive) hobby ever. Once it works and your flying something you built it will be all worth it. Sadly these bastards are making it illegal shortly

[@pimpedoutstereos9747]

Thankyou for sharing this. I was able to get my eachine qx95s into dfu mode after watching this and have got it on betaflight 3.3 now so I hope it flies more stable now

[@Dobemandan]

Another thing that's very important is that some usb cables don't work... Ones that are for charging only don't work. Swap cables before pulling hair out.

[@mickclitheroe8585]

I've got a big piece of yellow tape around my data cable now !

[@d1o2n4]

Swapped my existing cable for a gaming mouse cable I had spare and works great. Thanks heaps. Anyone experiencing connection issues should make sure its a data cable first.

[@jamz670]

hah hah. That's 45 mins of my life I'll never get back.

[@0xanier0]

You guys please check the cable u use, it keep mean the difference between frustration and buying another and/or difference FC.

[@MrSWUSH]

Dude you saved me so much frustration.....i tried 3 cords and nothing, pulled the cord that connects a samples board to my pc and bam worked like a charm!

[@WaynePilot]

After almost 4 yrs this video still fixes my issue. Thank you for the help👍

[@jrodrc4137]

Thank you so much for this Albert. I could not flash new firmware on my HGLRC f425. I tried Zadig with no luck. I tried the new driver that frequent flier talks about. I had to use impulse rc driver fix. Thank fully it was so easy to use, Im not good with computers. Just a few clicks. Now I rock the newest firmware and I am going to go watch your video on Betaflight 3.2 and set it up again. Thanks

[@nickhopkins3913]

Thanks for sharing. After quite a while of trying to find my issue it was fixed instantly with impulseRC driver fixer

[@bohdiwolf]

[@AlbertKimTV]

awesome!

Dude I have tried literally ALL the fixes and the problem still persists. Did you do anything other than just install the impulse fixer?

You are the man. The Impulse RC driver fixer worked for me. Thank yo so much

[@cw8165]

Thanks Albert. Had been banging my head all night with ELRS niggles and a quad that seemed dead under DFU. Didn't realise I needed a separate driver for DFU, your ExpressLRS firmware for SPI video and this one (and the Impulse RC fixer) sorted it out. Up into the air we go! Cheers

[@caymandiver75]

You need to make sure in Zadig you see STM32 bootloader NOT STM32 Virtual COM port. Typically you will see bootloader show up when you hold the button down on the FC and plug in USB. 1. Open Zadig 2. Choose Options > List All Devices 3. Select STM32 BOOTLOADER in the device list 4. Choose WinUSB (v6.x.x.x) in the right hand box 5. Click Replace Driver 6. Restart Chrome (make sure it is completely closed, logout and login if unsure) 7. Now the DFU device should be seen by Configurator

[@FrequentFlyerRC]

caymandiver75 yes, exactly! Zadig is for drivers of boards in DFU mode.. here, he's having a problem when not in DFU mode.. The Com port. First link in the welcome screen of the Betaflight configurator welcome screen.

Thank you, caymandiver75!

[@BasicFlyz]

what if the flight controller comes up unkown USB (Device Descriptor request failed)

[@RealHiipixel]

​@@BasicFlyz Yeah. I just got my first drone and I ran into this issue. It worked before but I think I flashed some incorrect firmware and now I can't find a way to connect my dron back to beta flight. It just shows up as Unknown USB Device.

[@ekyamanullah4637]

can anyone help me? I've gone halfway into the part where you try to configure your model onto betaflight. Whenever I try to connect it comes with an error screen saying "Non - Cleanifight/Betaflight firmware is not supported, except for CLI mode" Any suggestion on how to fix this?

[@FrequentFlyerRC]

Problem was the fact that the Zadig tool is for fixing the DFU driver! If the board doesn't connect and show up when in DFU mode then you use the Zadig tool to install the DFU driver which is why after you installed the driver from Zadig it later showed in DFU on the port. On the welcome screen of Betaflight it explains it all and actually has all the click abled links there on the Betaflight welcome screen. In Your case you just needed to click on the first link provided in the welcome screen. I hate that one because it makes you go back to your email to validate the download link 😆

[@AlbertKimTV]

+Frequent Flyer RC yay, even more confusion... gotta love this stuff...

[@Raad1982]

hope u get to read this. i have been using starf4 AIO FC for a while now. after updating to the latest betaflight 4.2.. flashed it and it will not even read USB anymore. now i am wishing i did not update anything and had left it as it is. do you have any idea what could be the problem ? there is no light or any signal or anything when i connect it to the USB like its dead but it it lights up when i connect the battery .. my other GepRC phoenix 2.5 connects fine to the betaflight configurator but i am hesitating to do any firmware update. i have tried the newest zadig and newest impuls .. but nothing. what could be the problem. please advise.

[@AlbertKimTV]

You may have flashed the wrong firmware or it got corrupted when you flashed it. Don't worry, just power up the board again with the bootloader button pressed down and it will power up in DFU mode and you can reflash it again.

Wow! Started checking my USB cables and that was the problem. Guys if you've installed all the drivers and are getting connection errors, check your USB cables first. A data cable that I got from Amazon for connecting my Android cellphone to my computer hooked me up to Betaflight the very first time I plugged it in. Set me up on COM 3 immediately. Thanks to Dobermandan for the heads up on this issue and to Albert for this video. Also thanks to Albert for helping me setup my new ET115 V2 with my Jumper T12 Plus in his other video on that subject.
