I'm attempting to control a relay (
https://www.phidgets.com/?&prodid=722) with a VINT Hub (
https://www.phidgets.com/?tier=3&catid= ... rodid=1202) using C# on linux.
The relay is connected on port 0 on the hub, which is connected with USB to my pc.
The following simple code produces a
Code: Select all
using Phidget22;
Console.WriteLine("Hello, World!");
DigitalOutput digitalOutput0 = new DigitalOutput();
digitalOutput0.IsHubPortDevice = true;
digitalOutput0.HubPort = 0;
digitalOutput0.Open(1000);
Console.WriteLine("Connected!");
I can confirm that the
is installed, and the Hello World examples for both C and Python both work.
The
nuget package is also installed in the given example.
Is only Mono supported for using C# with Phidgets?

Hi,
On Linux, you'll either have to run your program as root (sudo), or install the udev rule to allow access to Phidgets as a regular user.
You could try running as root just to confirm whether you can open the Phidget. If you are still having issues, enable logging in the library and see if there are any errors.

I have the following udev rule installed in /etc/udev/rules.d/99-libphidget22.rules:
Code: Select all
#All current and future Phidgets - Vendor = 0x06c2, Product = 0x0030 - 0x00a
SUBSYSTEMS=="usb", ACTION=="add", ATTRS{idVendor}=="06c2", ATTRS{idProduct}=="00[3-a][0-f]", MODE="666"
This comes from the documentation at
https://www.phidgets.com/docs/OS_-_Linux
Running this bit of code
Code: Select all
using Phidget22;
Console.WriteLine("Hello, World!");
DigitalOutput digitalOutput0 = new DigitalOutput();
digitalOutput0.IsHubPortDevice = true;
digitalOutput0.HubPort = 4;
digitalOutput0.Open(1000);
Console.WriteLine("Connected!");
produces this output, whether i run it as root nor not:
Code: Select all
Hello, World!

If I unplug the phidget from USB, i get

Can you post the output of lsusb?
Try increasing the open timeout?
Enable logging in the library and post the output?
