Help with drivers

[gabrielb09]

Im a student working in a lab and trying to build my own software to communicate with an Omega manometer (the HHP886U to be exact). I've stumbled upon your project while researching this and wanted to know how you found the drivers for all of the devices you use. I've been struggling to find the appropriate commands to send to my device to read the pressure from it.

Thank you for any help you can offer.
