Not likely those PCBs have gone through much testing on assembly line, how about 4... > If this FT232H board works, it would be an ideal replacement both for > commercial AMIDebug Rx / Ajays NET20DC (because much cheaper) and > FX2LP (because no DIY will be required).

FT232H could be made to work with linux kernel early_printk=dbgp but I don't think anyone has done that. FX2LP approach was able to mimic the net20dc USB descriptors, including the special response of debug feature and endpoint number assignment. > Will write an update when I'd get the boards and test them with AMD > G505S laptop.
