Hi all,

I am currently trying to run a DuinoMite (loaded with MMBasic 3.1) and a MaxiMite (also on MMBasic 3.1) on the same PC. The MM is externally powered, the DM powered via USB. All seems OK - both are accessible via TeraTerm individually - but when I connect both the devices at the same time, whichever one is plugged in first claims COM Port 4. I can verify this by then connecting to COM Port 4 via TeraTerm and if the Maxi was connected first, I get the "Maximite BASIC Version..." welcome. If the DM was connected first, I get the "DuinoMite MMBasic Version..." greeting.

Obviously only one of the *Mites is then accessible via TeraTerm. Is this an HID/VID issue perhaps? They are both identified in Device Manager as Communications Port - Silicon Chip USB Serial Port (COM4). There are two identical entries when they are both connected via USB.

I like them both (almost equally) and I don't want an internecine battle between my *mites taking place on my very own PC.

Clues?

Thanks in advance.

You can have more than one mite connected at the same time. On your setup it appears that the first one will be allocated COM4 so when the second is plugged in your operating system will allocate it a different COM number (probably COM5). This is because you can only have one device per COM port.

When both are simultaneously connected the entries in Device Manager should show the different COM numbers.

If you fire up a second copy of TerraTerm you will find that there is another COM port to connect to and your second mite will probably be on that. You can then copy and paste between mites... cool!!

Thanks Geoff - I sorted this out by going into the Windows Device Manager, and for one of the duplicate COM4 ports, I selected the Port Settings tab of the Properties dialog and then in the Advanced... dialog I changed the COM Port Number in the drop-down list to what I know was an unused port. A couple of physical connects/disconnects later and now I have both *Mites co-existing - happily ever after...

Cheers.
