Appreciate all your support.
Thank you.

We are facing the scenario to open 2 '

2/2/2

' devices on same process.
I cannot spot such 'C' API, which would open the specific device by
/dev/usb/xxx:yyy. or by device path name.

Thank you.

Hi, Question 1 We are using 2/2/2 phidget with the for digital outputs. There are 2 separate applications which needs to open the phidget, one for writing, the other one for reading, unfortunately the second application fails to attach the device. Is there a workaround or the resource is one/process...

I would go with this one.
