No luck, actually. :) My oscilloscope and the schematic say >> that the hardware is wired up properly, I'm just wondering if anyone has >> a similar configuration that's working for them--- and which kernel they >> are using? >> > > Is it with the OTG controller or with the EHCI controller? > The pins of the ISP1505 are tied to pins T24, T23, and so on of the OMAP3530CUS, which on my schematic are labeled UH0_D0, UH0_D1, etc. That's EHCI, right? But I have both the EHCI and MUSB drivers enabled, and both appear to initialize properly according to the kernel logs. > The NXP ISP1505 is supposed to be transparent - no programming usually > required. > That's what I thought.
