PicoScope removes USB-Oscilloscope

Postby NetoLE » Wed Feb 01, 2017 12:55 pm

I hope the title is suitable.

I'm experiencing a problem with mit USB Oscilloscope. If I connect it with the PC it's found and shown in the Device manager under "Pico Technology Instruments" (It's a 3000 Series, 3403D). As soon as I start the PicoScope Software it removes the device from the list and shows "no suitable device found". The trace.xml shows like this:

I uninstalled driver and software and reinstalled it, but that doesn't solve the problem. Doesn't matter if software form the CD or newest update from the website. OS is Windows 7, PC a DELL Optiplex 7020. No other USB devices on USB Controller,but mouse and keyboard. Connected with a Intel USB 3.0-Port and the cable out of the box.

best regards

Hello Felix,

Please check that your USB chipset drivers are up to date (these can be obtained from the Dell Support pages).

It might also be a case of insufficient power for the power-up process when the connection to the device is opened. Are you able to try a different USB cable or powered USB hub?

Does the PicoScope have any issues on another PC?

Hitesh

Thanks.

Updating the chipset and USB 3.0 driver from the DELL Homepage fixed it. The following happened (just so you know):
After rebooting after installing, I put in the USB 3.0 cable from PicoScope and it showed up in the device manager like before. After starting PicoScope it disappeared again, but now the symbol and tooltip for "installing new device" showed up and it installed the PicoScope driver again successfully it seems and It was recognized by the Pico-Software and is working.

Btw.: the bug didn't happen always before. After trying a lot and writing the topic I just tried again yesterday (before installing new drivers for chipset and USB) and is suddenly surprisingly worked. After that in the morning today (also before installing new drivers) it didn't work again.

thanks again for the help.

best regards
