Error message in Kess v2 firmware v4.036 Ksuite v2.22:
connection not established
I took this UL46 USB protection chip off my old Ktag board.
this is the UL46 USB protection chip
(if you don’t have this chip, go to the kess v2 vendor for it)
Then Kess v2 v4.036 is detected on usb :) Everything is ok so far.
