Test and Measurement Forum

Hi
I try to use a picoscope 2203 under Linux in three different machines with OpenSuse 11.1, 11.2(x86_64), 11.3 and fail in all of them.
When i run usbtest the output is :
Pico USB device found: /dev/bus/usb/001/005

- It belongs to root (which is you) who has permissions rw-
- The members of group root (which you are in) have permissions rw-
- Everyone else has permissions rw-
- You can write to this device and so will be able to use it.

Pico USB device not found. Please try again

I compile and run thePS2000con.c and the output is:
PS2000 driver example program
Version 1.0



Opening the device...
Handle: 0
Unable to open device
Unit Not Opened
Error Code: 3

Maybe is something wrong in the installation procedure that i follow.
What i did:
Install the RPM file with Yast
the lib files installed in /usr/local/lib,
and the header file in /usr/local/include/libps2000
Copy the 'PicoScope.conf' to /etc/ld.so.conf.d/
Run ldconfig as root
Copy the 95-pico.rules in /etc/udev/rules.d
Create with Yast a group named pico
Add user to pico group

Can someone see a mistake in this installation procedure? Did i miss something?

Thank you in advance

I have the same problem, with a picoscope 2203 and Ubuntu 10.04
I notice the lines:

Pico USB device found: /dev/bus/usb/001/005

(other numbers)
and then the last line:

Pico USB device not found. Please try again

which seems contradicting

The following is just an error in the script and can be safely ignored

Pico USB device not found. Please try again

Having just followed the installation instructions I have been able to successfully build and run the example code on Ubuntu 11.04

Please confirm if you can do the same and if not what errors do you get ?
