Acer laptop built-in webcam not recognized

Post by Mutusen » Sat Jan 13, 2018 8:47 am

Hi,

I installed Linux Mint two years ago and everything worked fine.Today, after an unrelated problem (X server wouldn't start), I figured it would be easier to reinstall the latest version of Linux Mint. Now everything still works fine, except my webcam is not recognized any more. The model of my laptop is Acer Aspire E 15.

There is nothing about video in /dev and the webcam is not present in lsusb:

I've found posts with similar problems, but nothing helpful so far. Does anyone have any experience with such issues?

I'm not seeing any USB cam device. Could that cam be on the PCI/PCIe bus?

Which version of Mint did you previously install that had the cam working?

Have you tried installing guvcview or cheese to test?

Might be errors in the hardware log to give a clue. Please run the following command and post back the results.

Code: Select all

dmesg | grep error

I installed it in February 2016, so if I'm not mistaken, it was 17.3 Rosa.

I've just install them, they both say "no video device found".

That device descriptor read error on usb might be the cam. I think the error -110 is insufficient power from this post at Ubuntu.

https://askubuntu.com/questions/644010/ ... -error-110

Have you tried disconnecting other USB devices that draw power.

To better look at USB, please run the following command and post back the results.

The only USB device was a wireless mouse, but I tried anyway to shut down, disconnect everything and restart. It didn't change anything.

The error was actually happening on Atheros AR3012 Bluetooth with ID 04ca:300b.

I don't see any cam device on USB or on PCI.

Edit: I'm guessing the cam is "Crystal Eye Webcam", which is normally USB. I have a client with Aspire One laptop, so I've see the cam working.

I do see a lot of discussion at the Acer Community on missing cam.
