There's probably a compatible driver already in the app. Use Scan Camera function to find compatible drivers.
First, make sure you can access the device's web login page using your mobile browser on *** 4g/3g/2g/g *** (anything but your home wifi).
See this link for info: viewtopic.php?f=8&t=47
Once that works, then try my app. The "Scan Camera" function can help when you're not sure of the make/model. Try scanning the device's WEB/MEDIA/MOBILE/DATA ports (shown in device settings).
If you still have problems, even AFTER scanning all known ports, then give me temporary access to it and I'll try to connect.
Just email me the web login URL and a temporary username/password.
Also, include the make/model and a product url link (if possible).
