But don't I already have the g_zero enabled via: CONFIG_USB_GADGET_MUSB_HDRC=y But lets assume that, for the time being, I'm only interested in USB Host. I had combed the mailing list looking for ISP1505 support and happened across this: > There's one problem here. If this is similar to isp1704, it doesn't have > a control interface.

The ISP1704 is very similar to the ISP1505, neither one has a control interface (like I2C), only straight ULPI. Does this mean that there is no "out of the box" support for straight ULPI in 2.6.29? If so, what would I need to do to support it? Rick
