Beginner Question on using the E220 library when the E220 is attached via USB.

Hello everyone, This is probably asked before, but I did try and look a bit around the forum before asking. I new to this stuff, so hopefully I provide the right info to help get an answer. I currently have 2 DSD Tech SH-L1A devices which have a CP210x USB UART and a E220-900T22D chip on them. I have made sure the devices both work as they should, that they communicate successfully across the fabric of space-time to each other. Now I want to do stuff with them, besides just type text in a terminal. I am very familiar with most code, not so much with using it to control little devices attached to a computer though. So, before I go banging my head against a wall trying to make things work, I have a question. My Question: Can I use the E220 library that you created @reef to set channel, and other various properties or functions in your library with the USB, or do I need to do something else? I have learned about how to send hex and such to see the device's properties and that all seems to just be straight forward. I just wasn't use if the library expected to communicate with the device via pins and other such things instead of a COM port. (Let me guess, the documentation that I skimmed through probably tells me how to do this right? Thanks in advance for any knowledge here. Regards,
