As I recall, there are two transceivers on that board: OTG, and non-OTG. Ideally both should work. I seem to recall positive reports about using the OTG transciever. > Thanks for any pointers, > > Kevin > > isp1301_omap 0-002d: chiprev 2.00, driver 24 August 2004 > MUX: initialized N21_1710_GPIO14 > usbmon: debugfs is not available > isp1301_omap 0-002d: A-Host sessions ok > ohci ohci: OMAP OHCI > ohci ohci: new USB bus registered, assigned bus number 1 > ohci ohci: irq 38, io mem 0xfffba000 > ohci ohci: init err (00000000 0000) That "init err" means the controlle wasn't responding to basic stuff. Like maybe it wasn't clocked correctly ... you could turn on USB_DEBUG in Kconfig and see if the register dump looks even vaguely sane (like, it should report three ports etc). - Dave > ohci ohci: can't start > ohci ohci: startup error -75 > ohci ohci: USB bus 1 deregistered > ohci: probe of ohci failed with error -75 >
