USB not reconized on cc3d. WHY?

3.01K viewsTricksenter

Have brand new cc3d flight cotroller and usb not reconized using libre pilot. Works fine with other cc3d boards. Also bought two D4R-ll from you in January,can I assume the firmware is updated to 27ms before I buy a taranus from you? One of youyr adds said you did that.Thanks Chris Pearson.

yes you have been a big help.Would love that coupon and is the taranus updated to the open tx. My computer skills are lacking,so I suppose it does’nt matter. Very intrerested in taranus so want to make sure it’s ready to go.I built a ZMR250,which is close to QAV250 which you program in. Thanks for your help. Chris Pearson

All D4R-II ordered from QuadQuestions have been updated to 27ms.


As for the CC3d, it’s hard to say.  It’s not something that we sell, so it’s hard to determine the issue.

I would recommend that you: “check drivers, check usb cable”  Beyond that, it’s hard to tell why you have connectivity issues. Perhaps a CC3D expert can chime in?

We would love to send you a coupon to get you into a flight controller that supports Betaflight. – if interested, email support@quadquestions .com


Our Taranis are upgraded with many models and a better voice pack-  this can help you get setup fast and with ease.
