Just give some generic tips: - check if you can read pid and vip of this ulpi transceiver - If you can't, please check if the clock of ulpi is existed or not, it is an external clock, and check the portsc.pts is set correctly for ulpi phy - Try to reset ulpi phy before any usb operations Peter > You can see my work (ugly hacking alert!) here: > http://git.o2s.ch/?p=linux-stable.git;a=shortlog;h=refs/heads/v3.15-z2760 > and can clone the repository from here: > git clone http://git.o2s.ch/git/linux-stable.git > Maybe you've got some idea, what I'm missing/doing wrong here?! > Please?!
