a friend of mine happenes to use a Liquivision X1 computer.
I understand libdivecomputer does not yet support that model, but wanted to ask whether there are any known attempts underway to change that?
Or would it be realistic to assume that borrowing that computer for just a few days trying to sniff its protocol would deliver enough information to support it?
I looked briefly at the Liquivision Xen/Xeo last year. But I didn't get very far due to a lack of time.
One of the problems with these devices is that capturing the communication is a bit more challenging. The Liquivision application uses the FTDI D2XX driver and library to talk to the device. This means there is no virtual COM port and thus capturing the serial communication isn't possible as far as I know. The alternative is to capture the usb communication. But because usb is a lot more verbose then plain serial communication, the result is much more difficult to interpret. I also don't know any relative easy to use applications to capture usb communication (like a portmon equivalent for usb).
