Scubapro Aladin Square

[vavincavent]

Hi,

I try with joined file scubapro_g2.c to download from scubapro square.

This is the log after failed download :

Subsurface: v4.7.4-1-g4d04f74312dc, built with libdivecomputer v0.6.0-

I join here the USB snif file that i have in a windows system with
USBlyser.

I hope someone can help me to add square like supporter divecomputer to
subsurface.
