Picoscope 2104 installs as Prolific Com4

pcbolt · Post by **pcbolt** » Thu Sep 19, 2013 5:27 am

Hi everyone.

I just recently acquired a Windows 8 machine and wanted to use it to run my Picoscope 2104 oscilloscope. I downloaded the software and it installed fine. However when I plugged the 2104 into the USB port, Win8 installed it as a USB Prolific serial port (COM 4). When I run PicoScope (6_r6_7_35), it fails to recognize any attached devices.

Any solution to this?

Does it work OK on a different PC ?

Is there anything elese connected to the USB ports ?
Have you tried different USB ports, preferably USB2 ones ?

Can you post the trace.xml file when Picoscope has failed to detect the scope. Let the detection fail and then close the application. You can find the file here

Hi Martyn -

Thanks for the reply.

The Picoscope 2104 worked fine on Win2000 and Win XP. I just installed the software on those machines and plugged the 2104 in and it worked right away.

I have tried all the other USB ports (2 USB 2's and one USB 3) and the only other device I have plugged in is a USB mouse.

In the device manage I get this error for the COMM 4 port it created when I plugged the 2104 in...

"This device cannot start. (Code 10)
A device which does not exist was specified."

Here is the trace log...
