Discussion - Software / Re: Unexpected invalid handle - conflict between two devices
« on: December 20, 2021, 03:50:39 PM »
hello,
Could you clarify if you are using the SIGMA 2 or the OMEGA 2, as you say both in the post. The SIGMA 2 is a full speed device, whilst the OMEGA 2 is a Hi speed device. the FT4232H is also a Hi speed device.
Is the only time the issue occurs when the SIGMA/OMEGA is connected before FT4232H is opened? And when it is just the FT4232H connected or it is opened before the other device is connected, everything works fine?
Here is some helpful documentation:
