trying to get a microscope camera to work

[systemchris]

on a standalone computer at work we had a usb microscope camera, which only currently works on XP of course

from running a lsusb -vv i get

I've installed v4l2 to see if there's anything it can do.... it knows when there's light or no light, but i get green lines darting about and not much else other than it showing light and dark

I'm not expecting any miracles, more guidance if theres anything which can point me in right way of getting this to work. I've tried the manufacturers (useless as usual since they wont help with vista drivers lol)

How hard is it to use windows driver information and the drivers which don't quite work to make a working driver? Like reverse engineering it?

Any info would be quite helpful even if it's a "impossible" answer

[jerrrys]

what is make and model of this microscope camera and what software are you using with it?

[systemchris]

it's a bruekhoven tcam 1.3MP, on windows with drivers it's called a scopetek 130 if that help

not fussed about software, it has software but generally any video viewer that can take a usb capture like a webcam will do

Hi,
I've got a 1.3 megapixel usb microscope (strictly down-market, from Maplin) and it works well with a program called "Cheese", available in Synaptic.
I'm still looking for a way to superimpose a scale on the image though.
Does anybody have any suggestions?
TTFN,
Roger49

When you do the "lsusb" try it this way:

lsusb -vv > out1 (before connecting the camera)

Then connect the camera to the USB port and do:

lsusb -vv > out2

Then do a diff:

diff out1 out2 > usbcamera

This will separate the camera's usb info from all the other usb info. Makes it easier for others to
read the important stuff and ignore the rest.

I also have a Microscope USB camera that needs a Linux driver and software. I will be willing to write a driver and software for it. But I don't have the necessary reference manual for it. And I no longer have access to serial data analysers (since I am retired) to use reverse engineering to find the command set used by the camera.
My camera is MU300 by AmScope. It only comes with drivers and software for Windows XP. This is
the USB data I get from lsusb:

I will now try to contact "Anchor Chips" to see what data they can provide me with.
