Is it possible to specify the current ANT+ USB stick to access it?

[peter279k]

As title, when I've the multiple ANT+ USB stick devices, I cannot use the openant to specify which one I need to use.

It always find the one of ANT+ USB stick devices. I also found that this line will cause this issue.

Is it possible to replace above line with the usb.core.find(find_all=True, idVendor=cls.ID_VENDOR, idProduct=cls.ID_PRODUCT)? And it can let developers choose the current ANT+ USB stick that they want to access.

I would suggest the init method should take an optional dev. The open method can then only call find if dev is None.

That would allow a user to instantiate the Driver with a device already found through whatever selection process they write.

Happy to review a PR if it's something you need and want to implement.
