What is a USBscope? A otoscope, boroscope, oscilliscope .........

Are you using windows? Mac? What operating system and do you have the right driver (to install) installed. Some USB scopes work with the driver of your webcam or one of your picture viewers.

So, make, type China?

Most of that is in the first post. Its a USB oscilloscope made by Elan which was a UK company. I have tried installing/downloading drivers a few time and just don't seem to be getting anywhere. I am on a Lenovo x60s laptop and running windows xp with all the service packs. I know the scope application uses Java and was hoping someone with more experiance than me could cast their eye on it and say "ah he need to install a hissyfrogmog"

I checked some links too. The company still exists and normally the scope comes with a disk. Perhaps try elan USBscope50. It gave me quite some links in my browser.

Thanks for reply. I did download original disk and went through the intall and everything. Maybe there is just something amiss with my laptops software. Its quite a nice scope thing that I just got off ebay and am sure its ok ... much more chance its software.

Any idea what driver you have installed? (works not for windows 7) but if the scope is old, you might need a XP driver or disk. I hope you can get it to work.

Looks like you need to install the latest Java runtime, or conversely maybe you need to install an older version of Java. You might also make sure that the Java directory is in your "path" statement. Good luck!

Working now! Thanks DogOfWar you were right. I removed modern java and installed old java and it works. I use NoScript in my browser so I am not worried about java exploits.Thanks. Here it is with my finger on the scope probe!
