Almost all USB Video Class (UVC) devices should work with the standard kernel driver (uvcvideo.ko), and show up as a standard V4L2 device.
fswebcam is one of many V4L2 client apps that should be able to view the images.

There are any number of V4L2 apps.
The normal GUI testing tool is qv4l2 (sudo apt-get install qv4l2). fswebcam would normally work, but may have something quirky with your camera.
Yavta?
Are you wanting a command line app of GUI? Does Cheese work for you on the Pi?
Too many questions and options.

basically give us more info

any error messages
show images from your laptop / the rpi
and all command lines etc

The output of "dmesg" would be useful too to see whether the kernel driver has logged any issues as it discovered the camera, or when you started streaming.

not directly
however
cannot get freq at ep 0x82
may mean that the camera is not getting enough power - do its LEDs come on when plugged in ?
what PSU are you powering the system by ?
do you get brown outs ?
I suspect the camera ..

"cannot get freq at ep 0x82" is actually an audio error
https://github.com/raspberrypi/linux/bl ... ock.c#L317
I'm assuming your camera also has a mic built in. Seeing as the comment 2 lines later says "some devices don't support reading" I'm suspecting that doesn't actually matter.

RaTTuS is quite correct that it could be a power issue. Your camera may well work off Windows 7 and Ubuntu on a PC - neither of those are running off a 5V power adapter.
You don't say which variant of the Pi you are using. If it is anything other than an original model A or B, then the power LED also doubles as a brownout indicator. Does the power LED go out or flash at all on your Pi? If so then get a better power supply, or connect the camera via a powered USB hub.

You still haven't answered the question as to what you have actually tried on the Pi. fswebcam is one tool you mention and say it gave black images. What else? qv4l2 would be my suggestion.
You mention cheese worked on Ubuntu - have you tried that on the Pi?
What resolutions are you trying? The spec claims up to 25MPix (heavily upscaled), and that is almost guaranteed to fail.

how are you powering the RPI ?
what PSU are you using ?
what are it's specs ?
post a link to it
do you get brown outs ?
are you using a decent Micro USB lead ?

OK, so if Cheese isn't installing then ignore it.

Qv4l2. Boot or otherwise start the GUI. Open a terminal window and enter "qv4l2". It'll open a GUI window which allows you to select V4L2 device, resolution, frame rate, and any other parameter that the device advertises that it supports.
There's a start button somewhere on the top bar (seem to recall it being a red circle as per normal video record symbol, but could be wrong). That'll open the selected device and start it streaming. That's about the lowest level test app with a GUI that exists.
