PicoScope 2203 freeze my computer

Postby mk » Thu Oct 16, 2008 11:08 am

Hello,

I tried to install the Picoscope on my computer at work.
When i plug the Picoscope i get the following message:
"No suitable device was found...".
The driver is installed, but i can not find it in the device manager.
The system freezes at reboot.

At home everything is all right with the software and i can see changes in the device manager, when i plug the picoscope in.

Please help, thanks.

Hi mk,

Do you have admin rights on your computer at work? Please ensure it does.

Kind regards

Shure, i have admin-rights.

Sometimes i can see the picoscope in my device manager, but there are two drivers loaded. The picopp.sys and the libusb0.sys.

Hi what operating system are you using? The device should only be using the picopp.sys.

I use Win XP SP3.

We used a development board with an Cypress USB Controller FX2 some time ago... is that the reason?

How can i force the correct driver?

Hi mk,

I do not know what libusb0.sys is from but I would suggest looking on the web. If there any traces of that development board software then remove it (if you don't need it ofcourse) and see if the problem persists.

Kind regards

Hi

The device should only be using picopp.sys. Try using a powered USB hub and plug in the scope into it. When the hardware wizzard comes up select to "Install from a specific location (Advanced)" then browse the driver and search for the picopp.inf on c:\WINDOWS\inf\. then continue with the installation.

Let me know how you get on.

Kind regards
