no, not all of them"… I have a pair of NHS Siemens/Signia Teneo M+ which did not show as even existing in Connexx 6, 7 or 8.x.x, but once connected (via USB HiPro, CS44’s & #13 battery pills) were immediately detected & fully supported - I can read my Specsavers/NHS Audi- entered Audiogram, redo 1st fit & fine tuning, change & reassign programs/buttons and read/respond to logging data in any version of connexx 8.x.x i have tried - it even loads in the model specific html help & info links showing detailed fitting / connection guides,.etc.
