As GNU GPL v2.0 allows commercial use as long as we disclose sources under the same license. I have some confusion about use of such application. This is my situation:
The commercial software I am developing needs to use virtual USB ports. I can't write a software for USB port virtualization. But there is a software with GNU GPLv2.0 license that does it. I am not incorporating their code in my software.
But the user will have to create(or I might set up virtual ports) on their computer.
Does that mean I need to disclose the source of my software too under GNU GPLv2.0?
Can I ship/recommend such software separately along with my product?
Can I sell the computers with GNU GPL v2.0 software along with my software installed?
