I haven't set up my old USB webcam in some time, not since I moved my local machines from Ubuntu to Arch.
At the moment I'm getting "No device found" from cheese, and only black screen from skype (skypeforlinux), but it did come up on cheese for a bit (see below)!
I believe it is Gigaware 250-157 VGA Webcam with Mic (looks like it on Amazon).
Here is some info from lsmod:
lsmod | grep gspca
gspca_pac7302 20480 0
gspca_main 36864 1 gspca_pac7302
v4l2_common 16384 1 gspca_main
videodev 208896 3 v4l2_common,gspca_pac7302,gspca_main
usbcore 286720 12 usbhid,snd_usb_audio,usb_storage,ehci_hcd,uhci_hcd,xhci_pci,snd_usbmidi_lib,gspca_pac7302,uas,gspca_main,xhci_hcd,ehci_pci
Strangely, it DID come up on cheese at one point. I don't think I did anything after except possibly reboot. Now it just gives "No device found" again.
Here's what I get running 'cheese' from the command line:
$ cheese

in the lsusb output the camera shows as

I'm out of ideas. Anybody??
Also, this thing is pretty ancient. If someone thinks another inexpensive webcam would be a better bet (both in terms of >working< and maybe in terms of quality too), I'm all ears.

UPDATE:
Now cheese seems to work with:
alias cheese='LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so cheese'
skypeforlinux, I've tried all the various LD_PRELOAD options out there, and still get black screen.
I also tried to install skype-legacy, to no avail:
$ packer -S skype-legacy
