Solved. Yoga 910 no camera and an unknonw USB device

#1 Post by cfds » Sun Oct 31, 2021 10:31 am

Lenovo Yoga 910, I did a fresh windows 10 install on a new SSD (512GB), in order to prepare the laptop to be sold.
All went well except that when opening the camera app I get an error code 0xA00F4244 - no CamerasAreAttached.
In the device manager there is no camera listed but under the universal serial bus controller I have 1 unknown USB device marked as device descriptor request failed.
I think this is my integrated camera...
I followed the google instructions I found online like uninstalling the device and rebooting without any help. Fast startup disconnected does not solve my issue either.
I have downloaded and installed all drivers from the lenovo site, installing the camera driver does not solve my problem...
Just to confirm, the camera functions well with the old SSD (256GB) which still contains its image so its not a hardware problem but a software problem.

Any tips, should I dive into the register? Delete the unknown USB device?

Thx,

Yves

After I refitted the original SSD, ran the laptop and reinstalled the new SSD the problem has been solved...I still don't understand how but it has been solved.
The Camera works and the unknown device has disappeared. Happy days!
