Because so many have been writing and commenting on My Blue Yeti Microphone Repair Video, I’ve taken the time to make this page to give you more detailed instructions on how to fix the Blue Yeti showing as USB Advanced Audio Device problem.
Why is my Blue Yeti showing as USB Advanced Audio Device?
Before the fix, let’s understand why this happens. The Blue Yeti showing up as USB Advanced Audio Device is caused by corrupted or erased EEPROM firmware on the microphone’s audio chip.
Most USB microphones of different brands use a CM6400X chip from CMedia. This chip is very susceptible to voltage spikes — plugging into a USB 3.0 or 3.1 port can erase its EEPROM. When that happens, the hardware loses its identity and Windows detects it as a generic USB Advanced Audio Device instead of your Blue Yeti.
This causes: low audio quality, saturated/distorted sound, software not detecting the mic, and more.
CM6400 CMEDIA — the chip inside your Blue Yeti
Most manufacturers don’t offer a true fix — they only offer an RMA replacement, which is useless once the warranty expires. That’s why this solution exists: restoring the firmware directly by flashing the EEPROM.
Blue/Logitech support confirming there is no official solution for this problem.

Troubleshooting — Common Errors
Connection Error
Fix: Connect the microphone to a USB 2.0 port or try a different USB port.
EEPROM IS EMPTY !!!
This is normal — it means your EEPROM has no data. That’s exactly what this guide fixes: writing the correct firmware back onto the chip so the Blue Yeti is recognized properly again.
Frequently Asked Questions
Why does my Blue Yeti show as USB Advanced Audio Device?
The Blue Yeti shows as USB Advanced Audio Device because the EEPROM firmware on the CMedia CM6400X chip has been erased, usually by connecting to a USB 3.0 port with voltage fluctuations. When the EEPROM is empty, Windows can’t identify the microphone and shows it as a generic USB audio device.
How do I fix Blue Yeti USB Advanced Audio Device?
Download Config6400.exe from the link above, connect your microphone to a USB 2.0 port, enter the VID and PID values from Device Manager, then flash the BACKUP_FIRM.bin firmware file. After unplugging and replugging, your Blue Yeti should be recognized correctly.
Does this fix work for other microphones besides Blue Yeti?
Yes. This fix works for any USB microphone using the CMedia CM6400 chip, including HyperX QuadCast, Razer Seiren, FIFINE microphones, and many others that show up as USB Advanced Audio Device in Windows.
Why does my Blue Yeti only work when I unplug and replug it?
If your Blue Yeti only works after unplugging and replugging, the EEPROM is likely partially corrupted. The Config6400 fix in this guide will permanently restore the firmware so it initializes correctly every time.
Is Config6400 safe to use?
Config6400 is a safe EEPROM flash tool developed for CMedia chips. Always back up your current EEPROM data before flashing (step 5 above). Use it at your own risk — SharkLatan.com is not responsible for any damage from improper use.
Fix HyperX QuadCast Showing as USB Advanced Audio Device
The HyperX QuadCast showing as USB Advanced Audio Device is the exact same problem — same CMedia CM6400 chip, same EEPROM corruption. The fix is identical: use Config6400 following the steps above.
Watch the full video tutorial specifically for HyperX QuadCast USB Advanced Audio Device fix:
This fix also works for: HyperX SoloCast, Razer Seiren, FIFINE, Tonor, Maono, Samson, and any other USB microphone that shows up as USB Advanced Audio Device in Windows Device Manager.
HyperX QuadCast USB Advanced Audio Device — FAQ
Why is my HyperX QuadCast showing as USB Advanced Audio Device?
The HyperX QuadCast shows as USB Advanced Audio Device because its CMedia CM6400 EEPROM chip has been erased or corrupted, typically from connecting to a USB 3.0/3.1 port. When the chip loses its firmware, Windows detects it as a generic audio device.
How do I fix HyperX QuadCast USB Advanced Audio Device?
Use the same Config6400 tool described above. Connect to a USB 2.0 port, enter the VID/PID from Device Manager, and flash the BACKUP_FIRM.bin file. After unplugging and replugging, your HyperX QuadCast will be recognized correctly again.

Advanced Troubleshooting
Cannot find HID device — Config6400 error
The “Cannot find HID device” error is the most common issue. Try in this order:
- Use a USB 2.0 port — USB 3.0/3.1 ports often cannot communicate with the EEPROM. Look for a black or white port (not blue).
- Try a different cable — a faulty cable can block data. Use the original cable if possible.
- Uninstall virtual audio software — VoiceMeeter, Virtual Audio Cable, and similar programs block detection. Uninstall and reboot.
- Run Config6400 as Administrator — right-click Config6400.exe and select Run as administrator.
- Try on a different computer — an older laptop with native USB 2.0 ports works best.
- Uninstall all USB audio drivers — in Device Manager, uninstall all USB Audio devices, reboot, then retry.
Blue Yeti shows as USB Advanced Audio Device after Windows update
Windows updates can overwrite USB audio drivers and reset the microphone identity. If your Blue Yeti stopped working after a Windows update, the EEPROM needs to be reflashed using the same Config6400 steps above.
Blue Sherpa does not recognize Blue Yeti after fix
After flashing, Blue Sherpa may still not detect the mic if the serial number does not match. Try: uninstall Blue Sherpa completely, reboot, connect the mic first, then reinstall Blue Sherpa.
Fix on Mac — USB Advanced Audio Device on macOS
Config6400 is Windows-only and does not run on macOS. The mic still works as a generic USB audio device on Mac. To reflash on Mac: borrow a Windows PC or run Windows in a virtual machine, flash the EEPROM with Config6400, then return the mic to your Mac. Using a USB 2.0 hub also helps prevent the EEPROM from being erased again.
Blue Yeti Pro showing as USB Advanced Audio Device
The Blue Yeti Pro (VID: 074D, PID: 0002) uses a different chip incompatible with Config6400. If your Yeti Pro is not detected by G Hub or Blue Sherpa, the fix is reinstalling the official Blue USB Audio 2.0 driver — not flashing the EEPROM.
“WARNING: Your EEPROM is Empty” — This is NOT an Error
This is one of the most misunderstood messages in the entire fix process. When Config6400 shows “WARNING: Your EEPROM is Empty!!!”, many users panic and think something went wrong. It did not.
This warning is actually confirmation that you are in the right place. Here is what it means:
Your EEPROM is empty because the chip lost its firmware data — that is exactly the problem we are fixing. Config6400 successfully connected to the chip and is telling you it found nothing written on it. This is expected. Click OK and continue with the next step.
What to do when you see “EEPROM is Empty”
- Click OK to dismiss the warning — do not close the program
- Skip the backup step (there is nothing to back up since the EEPROM is empty)
- Go directly to File → EEPROM and select the BACKUP_FIRM.bin file from your download
- Wait for the flash to complete and the unplug/replug message to appear
- Unplug and replug your microphone — it should now be recognized correctly
The warning appears because the EEPROM has no data at all — not even corrupted data. This actually makes the fix easier and more reliable, since you are writing to a completely blank chip with no conflicts.
Difference between “EEPROM is Empty” warning and a real error
| Message | What it means | What to do |
|---|---|---|
| WARNING: Your EEPROM is Empty!!! | Normal — chip has no firmware. This is what you are fixing. | Click OK and flash BACKUP_FIRM.bin |
| Cannot find HID device!!! | Config6400 cannot connect to the mic | Use USB 2.0 port, try different cable, run as administrator |
| Connection Error | USB port incompatible or mic not detected | Switch to USB 2.0 port |
| Write Error | Flash failed mid-process | Retry on different USB 2.0 port |
If you see “WARNING: Your EEPROM is Empty” — you are on track. Keep going.
Why Blue Yeti Shows as USB Advanced Audio Device — Technical Explanation
The root cause is the CMedia CM6400X chip inside the Blue Yeti. This chip stores all configuration in its EEPROM: device name, vendor ID, product ID, audio presets and gain settings. When the EEPROM gets corrupted — most commonly from USB 3.0 voltage fluctuations or a failed Blue Sherpa update — the chip loses its identity and Windows labels it as USB Advanced Audio Device.
The Config6400 fix restores the firmware by writing a known-good BACKUP_FIRM.bin directly to the EEPROM via the HID interface. This solution was originally discovered and published by SharkLatan in January 2021 — the first public fix for this problem. The BACKUP_FIRM.bin was extracted through reverse engineering of the original Blue Yeti EEPROM.
Hola Shark and thank you so much for this guide ! I have successfully used this fix and shared the link with a few friends on ifixit and hackaday forums.
Recently I got a Blue Yeti that has an internal failure inside the CM6400 chip ( DAC failure) and needs to be replaced. Installed a replacement chip bought from ebay, but the seller later admitted it his chip have never been programmed and they need programming to can function. So the chip i got is blank, it doesn’t have the factory programming (described in the datasheet) of the USB descriptor, so it is useless in this state: USB not recognized, no talking to the EEPROM etc.
Could you please give me any advice if you know anything about this or should I just get a new chip (programmed) from other sellers ?
Thank you again for helping a lot of people with your guide !!!
Hello, could you program the chip, a user on YouTube uploaded the process of how to do it on Youtube.
https://www.youtube.com/watch?v=4tVpBJpS8zM&t=371s&ab_channel=KikiHobbyRepair
hello were you able to flash the chip somehow? I think I also got chips without bootloader/firmware/etc. so it doesn’t show up in device manager
Hi.
I have used your guide to fix razer-seiren X. Flashed blue yeti rom and so far it work as it should, thank you very much.
For better visibility I’ve posted a discussion on reddit which points at your blog. If you find it disturbing, please reach me and I will delete it. Although I hope it will help other people with this issue, as it took me quite a lot of googling until I found your solution in English.
Oh I forgot to post the link, sorry:
