Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 8087:0a2b Intel Corp. Bus 001 Device 002: ID 1c7a:0603 LighTuning Technology Inc. Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub So I contacted Novatech's support. They told me that the webcam is 'UVC Camera Bison Fix BN8VU6VTH-020 2M FHD slim 0V2724 FW0605 W/LED W/Array Mic.'
Although googling most of this didn't reveal anything. Next, I try various other things unsuccessfully, mostly to do with loading and reloading the uvcvideo module trying to get debug output, and pressing various Fn+F(x) key combinations hoping to turn the webcam on in hardware (various people have had some success by pressing Fn+F10). There weren't any camera options in the bios. I called it a night some time after trying to load a uvcvideo module I compiled (in the following dmesg, 23822 - 24139).
Resume from suspend isn't working yet, so I just leave my laptop on. However, the screen blanks after 5 minutes. Weirdly, the following morning, after I found something very promising in dmesg (23). Then, 8 minutes later, after the laptop screen blanking, I wake it up, and see the same output again (45).

The webcam still isn't detected by guvcview though: So, it looks like my camera is physically attached to my system, through PCI address 0000:00:14.0, which corresponds to some kind of internal USB port. It also looks like it's only being detected when my laptop wakes up from a low power state, then the USB interface disconnects. I'll post more as I find it out. However, I'd be very grateful to anyone who could point me in the right direction! Last edited by ajc0 (2016-07-17 23:33:19).

Jul 10, 2018 - BISONCAM LINUX DRIVER - The card reader in my case. As well, please remove the tag: Super User works best with JavaScript enabled. Both are listed in Windows' Device Manager as 'BisonCam, NB Pro'. Using Windows' drivers I cannot get either camera to work. Both are enabled in Device Manager.

Guvcview now detects my webcam, but it doesn't 'work'.
I'm not able to explain why the camera now appears in lsusb -t, however, I did add the following lines to /etc/modprobe.d/something.conf. Options usbcore autosuspend=-1 # My hypothesis was that the USB autosuspending might be breaking the webcam options uvcvideo trace=0xfff quirks=0x100 # Someone had used this quirks option in a forum post about BisonCam I tried quirks=0x100 because someone mentioned it on a forum post somewhere. Next, I reloaded uvcvideo with quirks=0x102 and it broke. After going back to quirks 0x100, the camera was still broken.
Here is my dmesg: Here is the full output of lsusb -v: - as weird as it may sound, lsusb -v has never shown me anything that could be close to a camera before! Karaoke software for mac. With these random camera events, maybe the device isn't usually getting power through the USB? There is a camera keyboard button, which I've tried, but there's no associated light indicating that the camera is on.
