@Davax... I believe
@StefanM is on the trail of the fox.
Seems the USB driver may not work in Windows 8, 8.1, or 10 after scouring the forums across the Interwebz.
That Tasco microscope was made by a company called
Bightwell Technologies Ltd. in China... just a bit of info, here.
However, all may not be lost. I don't have one to test with to see if these options posted in this thread I found work or not... but, if, you are on WIndows 8, 8.1 or 10, then, you may want to try them.
The post I am quoting is a good starting point, possibly. Others were having trouble with .net and such. Some said that the software works, but the USB driver won't work.
A couple found different software work arounds.
Quote from BleepingComputer,
USB microscope not working after Windows 10 update :
How to use USB Microscope previously OK on PC with Windows XP, 7, 8 but not working on a PC running Windows 10 ( say after update)
I too had problems with a USB microscope previously running perfectly on 2 computers I have - one running XP and the other running Windows 7
When I updated the Windows 7 computer to Windows 10 with the free update the microscope failed to work ( still OK on the XP computer)
I tried the work-arounds mentioned previously on this forum with no success.
I found a simple answer on the Microsoft help website - Windows 10 has a dedicated camera app and this worked for me. The app can be accessed on a Windows 10 computer as follows--
Connect the USB microscope to the computer as usual.
In "Search Windows" ( just to the right of START icon on the bottom bar ) enter Camera.
Usually the first (top) result will be the dedicated camera app (may see it as Camera- Trusted Windows Store App)
Click on this and hey presto you should see an image from your microscope and be able to take a photo
If worse comes to worse... try software and drivers from a vendor of Brightwell Products, like
Dino-Lite's products
Also, this page at Dino-Lite is very interesting and may be of use...
Using older models with Windows 8 and 10
Quote from the page and they have a solution, you could try:
By default Windows 8 and Windows 10 require that all device drivers have a digital signature. Some Dino-Lite models such as AM211, AM311(S)(H), AM313, AM411, and AM413 are older than Windows 8 and do not have a digital signature. To install these models on Windows 8 or above, the requirement for drivers to have a digital signature must be temporarily disabled.
Most of this is assuming you are on the newer Windows versions.
It does help troubleshooting, if the system specs are filled out.
