Oculus Sensor Firmware Error!! Please Help!

Ziegs4LifeZiegs4Life Posts: 1

Hello Oculus Rifters,

So for 5 straight days I have been troubleshooting the Firmware Sensor Error CV1 problem with everything I could find online to fix the solution but nothing worked. Im using the ASUS G20cb computer running Windows 10 64bit. I click the oculus firmware update and it begins the update, during that time I hear the Windows sound of a USB port being plugged in and unplugged twice. After I hear that sound, it shows that there was a sensor error and could not update firmware. Windows shows that the sensor is connected, up to date and working properly. I have uninstalled and reinstalled oculus and all drivers, plugged into different USB 3 ports, reinstalled all oculus drivers, and updated all ASUS USB, BIOS, ect. drivers as well. Sensor worked fine until oculus firmware Sensor update was requested. 

Since the oculus was working before the Windows Anniversary update, I thought a Factory reset of the ASUS G20cb would fix it (SINCE IT WAS AN OCULUS READY PC), which rolls back before the windows anniversary and deletes all files and programs that were on the computer. Believe me, this was my last resort of fixing it because I didnt want to lose everything I had on the computer. Turns out after the factory reset and loading the oculus program back on the computer, it still comes up with a SENSOR FIRMWARE ERROR!

I did a SECOND factory reset and this time ran all the windows Anniversary updates before I installed the oculus program, but I am still getting the same Oculus Sensor error. My computer says all of my USB 2.0, 3.0, and 3.1 drives are working properly, so it is nothing wrong on my end of the computer. 

The ASUS 3.0 USB shows it is plugged in and working correctly, and in the Oculus Device Setting it shows connected, but I get a notification that pops up in the bottom right of my screen that says cannot find sensor please connect. 

****When I look at the Sensor device in Oculus setting it shows the error 178/unknown (Update Required to 178/e9c7e04064ed1bd7a089e738b638b4c8467aa843-DIRTY)

Do I just need a new Oculus Sensor!!??

Please, any insight on this problem would help me out! Thank You!

    It may be a USB issue. I would try different USB ports (USB 2.0 can work better). You can also try getting this USB add-on card.
    Finally, you can try plugging the hardware into a different computer as you may be able to update the firmware there and then switch back to the first computer. Hope that helps.

    Been playing with my CV1 uneventfully til i updated to Windows 10 creator update, then Oculus app require me to update the sensor firmware (unable to). Call Oculus CS, not any bit helpful at all.

    Then i roll back to previous Windows 10, no more ask for Sensor firmware update in Oculus.
    However, same issue comes again after my Windows updated a Cumulative Update at 18 APR.

    Rift sensor shows normal in Device manager

    Anyone here encounter the same?

    Has anyone found a solution to this? I'm having the same problem.
    Tried it on 3 different PCs. All Win 10, one is without the creators update.
    Also tried different USB ports (2.0 + 3.0), but nothing worked.

    Any solution ????
     I have the same problem. 
    I already accomplished everything, I can not stand it anymore
  • Felix94KFelix94K Posts: 2
    I contacted oculus support and they told me to send the sensor in. So it's probably a hardware issue.

    Haven't gotten it back though and according to UPS it's been 3 weeks since they received the package. Originally they said it would take 8-12 business days (including shipping) to replace it. It's day 16 now and I haven't heard anything from them, not even that they received the item. So far I'm pretty disappointed with the customer support here.

    I think the problem is the sensor that comes with the touch controllers is just poor quality. That same sensor is the one that has been not working for me for over 2 weeks now and it has been a week now since I heard anything from support on the issue aside from an automated email that said : 

    Thanks for reaching out to Oculus Support.
    We sincerely apologize that we have not yet had time to review your case.
    At this time, we have a larger volume of tickets than usual. Your ticket will be handled in the order it was received.
    Thank you for your continued patience and understanding.

    That was after having daily conversations with them, providing them serial numbers, logs, etc, now they are simply not replying to me. Which tells me that the sensor that comes with the touch controller bundle, in order to make it cheaper.... is cheaper. Probably bad materials and shitty craftsmanship to try and save money to make it cost less. Now they are swamped with people having similar issues.

    I have the same problem with receiving errors on one computer but both sensors work correctly with another computer.  Both are Dell computers one Alienware and one XPS w/ added USB 3.0 controller.  The sensors will not work on USB 3.0 ports on the XPS system but the headset USB3.0 does.  On the XPS I ended up using both sensors on USB 2.0 ports and it works well, im sure it doesn't transfer info as fast but I cant notice. 

    Hope this helps,

    my "Firmware update" issue wasn't solved since April. And I try install it again today and still the same bad result. I tend to think this is not the hardware (sensor) problem. Since the issue shown after an update of Windows 10 (back to March/April). It looks more like the error caused by Windows/Motherboard driver compatibility to this sensor.

    Oculus Rift has been the most disappointing purchase of my life...and I owned a sega saturn at 600 dollars day one I paid 399 for the rift and feel ripped off. I'm sick and tired of shit not getting fixed. I'm asking for a refund or replacement if not VIVE here i come, my nephew has had one for over a year now and loves it.

    NVM didn't realize this was a necrothread....

    @andest2003 open a support ticket, they'll probably ultimately have you RMA it, that's what happened to others in this thread.

    Ok. Fixed by rerunning the Oculus driver manually (Program Files\Oculus\Support\oculus-drivers).

    Sensor issue. One sensor stopped working. Then 1 week later?
     Ya. Guess what, the other one stops to. Says its off.
    I don't think anything is wrong with the sensors tho.
    Something about a certificate I am starting to see here.
    always something new. Never the same problem.
    so inventing new fixes has become a issue.
    If a problem arrives and is completely new, how do you go about it?
    the other sensor doesn't show up at all, but I hear it initialize when I plug it in. 
    Usually there lol
