It's been more than a year since I made a release of UsbSerial and I don't really think that's going to change in the short term.
For that reason I would really welcome a collaborator(s) to this project. Ideally they should have:

• Good Android knowledge
• Understanding of USB protocols
• Accessibility to the hardware that this project requires (FTDI, CP210x...)

If you are interested please write to felhr85@gmail.com

Thank you 😊
