OneWire cannot find devices on 4.2+EMX Spider

I’ve got another problem trying to make 4.2 work with my project on a EMX Spider.
After the upgrade to 4.2, I had to modify the code a bit since OneWire is now part of .Net MF instead of GHI lib.

Old code to search a device (working with a DS2413 on .Net MF 4.1):


            mOneWire = new OneWire((Cpu.Pin)20);
            byte[] romNumber = new byte[8];

            if (mOneWire.Reset()) {
                mOneWire.Search_Restart();
                bool deviceFound = false;

                do {
                    deviceFound = mOneWire.Search_GetNextDevice(romNumber);
                    if (deviceFound) {
                        Debug.Print("Device found");                        
                    }

                } while (deviceFound == true);
            }

New code (I tried a few ways to test):

try {
                OneWire ow = new OneWire(new OutputPort(EMX.Pin.IO20, false));
                int num = ow.FindFirstDevice(true, false);
                int test = ow.TouchReset();
                ArrayList deviceList = ow.FindAllDevices();


            } catch {

            }

All 3 methods above (FindFirstDevice(), TouchReset() and FindAllDevices) return 0 or empty list (but no exceptions)
Maybe I should not use Pin20 and try another?
Thanks for the help!

Another customer reported onewire not working and we will look into this in short days.
