Eos Family Welcome Screen Hangs if Hog 4 PC is Running


I am running Hog 4 PC and when I try to launch Eos, the Eos Family Welcome Screen will hang or freeze.


With the release of Hog 4 PC v3.12.0, Hog 4 PC can utilize the ETCnomad Dongle and Gadget II. If the Gadget II is plugged into your computer and Hog 4 PC is running, Eos may hang when you try to launch it.

Any program that can utilize the Gadget II (Eos, Cobalt, Hog 4 PC, Net3 Concert, etc.) is only intended to be used one at a time. If more than one program is attempting to communicate with the Gadget II, that program or the Gadget II connection may be unreliable.

If you need to switch to a different program listed above, you must make sure that all programs are closed before launching a new one.


Hog 4 PC and ETCnomad use different drivers to control the Gadget II.  When Hog 4 PC is launched, it connects to the Gadget II with its drivers:


When Hog 4 PC is closed, it reverts back to the ETCnomad driver for control of the Gadget II.  If Hog 4 PC crashes or is force-quit, this reversion does not occur.  In that case, simply 

- Close the ETCnomad Shell, if it's open
- Open Hog 4 PC
- Close Hog 4 PC
- Relaunch the ETCnomad shell

The GadgetII Driver should appear under "Universal Serial Bus controllers"
