Lenovo EasyCamera stops working after a while - Ubuntu 18.04

Question

I have a refurbished Lenovo Ideapad 320 notebook, which i bought like 9 months ago. I started using its integrated camera (Lenovo EasyCamera) a few days ago, for videocalls anly. What i found strange is that, just after i boot up to Ubuntu 18.04, it works good and its sidelight is permanently turned on; but then, after being idle for a while or after keeping the camera on, it practically dies and stops working, all of a sudden. I don't know if it may be a driver, power, or any other kind of issue.

I have checked the output of sudo lshw on both times and, at the usb part (given the camera is internally connected via USB, as far as i know), it says this:

• Right after booting up, with camera working:

• After camera has stopped working:

                   configuration: driver=btusb maxpower=500mA speed=12Mbit/s

As well, i unsuccessfully tried:

• Unloading and reloading the uvcvideo kernel module on the run.
• Explicitly loading the uvcvideo kernel module at boot up, adding a line with its name at the /etc/modules file.
• Pressing both Fn+Esc and every hotkey my keyboard layout shows a sign of the screen or camera (Fn+F6, Fn+F8 and Fn+F10).
• Using the Cheese and GTK UVC Video Viewer softwares to test the camera (none of them recognized it).

As an extra data, i got the logs of the journalctl result about this module, and found this:

mar 24 18:35:08 i320 kernel: uvcvideo: Found UVC 1.00 device EasyCamera (5986:210f)

mar 24 18:35:06 i320 systemd-modules-load[317]: Inserted module 'uvcvideo'

Should anyone know how to solve this, or have an idea that may help me find out what's going on, please let me know. I'll really appreciate it.
