Hmm.... You have many ukphys there. :-) I think the PHY attached to the USB controller is ukphy2. The OUI indicates its maker is ASIX. Unfortunately there is no dedicated PHY driver for this PHY. I guess it may use a modified CICADA PHY though. Updated driver to force GPIO configuration for this PHY. Would you try again after downloading if_axe.c/if_axereg.h? It may show "unknown PHY mode : 0xXX" if my guess is wrong. > > >> ue1: <USB Ethernet> on axe1 > >> ue1: Ethernet address: "my mac shown here :)" > >> ue1: link state changed to DOWN > >> ue1: link state changed to UP > >> ue1: link state changed to DOWN > >> ue1: link state changed to UP > >> ue1: link state changed to DOWN > >> ue1: link state changed to UP > >> ue1: link state changed to DOWN > >> ue1: link state changed to UP > >> ue1: link state changed to DOWN > >> ue1: link state changed to UP > >> ue1: link state changed to DOWN > >> ue1: link state changed to UP > >> ue1: link state changed to DOWN > >> ue1: link state changed to UP > >> ue1: link state changed to DOWN > >> ue1: link state changed to UP > >> ue1: link state changed to DOWN > >> ue1: link state changed to UP > >> ue1: link state changed to DOWN > >> ue1: link state changed to UP > >> ue1: link state changed to DOWN > >> ue1: link state changed to UP > >> ue1: link state changed to DOWN > >> ue1: link state changed to UP > >> ue1: link state changed to DOWN > >> ue1: link state changed to UP > >> ue1: link state changed to DOWN > >> ue1: link state changed to UP > >> ugen1.2: <Microsoft> at usbus1 (disconnected) > >> ukbd0: at uhub1, port 1, addr 2 (disconnected) > >> ums0: at uhub1, port 1, addr 2 (disconnected) > >> uhid0: at uhub1, port 1, addr 2 (disconnected) > >> ue1: link state changed to DOWN > >> ue1: link state changed to UP > >> > >> the good thing is, it usually never got recognized, and was said not to > >> have a PHY (or something alike). > >> > > > > Are you using 8.1-RELEASE?
