Odd. Presumably earlier kernels worked for you; you should find out when it stopped working. It's possible some of the recent updates for OSK stomped on Innovator or 1510 support. If you're feeling adventurous, try the USB clock gating patch that I posted on Monday: http://linux.omap.com/pipermail/linux-omap-open-source/2005-February/003019.html If anything, I'd have expected that patch to break something on Innovator, rather than fix anything, so don't get your hopes up. (The clock tree on 1510 is much simpler than on newer chips, and it's possible that "usb_clko" acts differently too ... but it looked to me like enabling it was just "cargo cult" code copied from the original MontaVista support.) > I read on some threads that Innovator had some problems in it's wiring > and because of that USB host was not working. Does anyone know > anything about this? Let's see. Two of the three ports are accessible through OHCI, but multiplexing for one of them interferes with UART2. So one thing to try is using the other accessible host port. (You are using the custom cables that came with your Innovator, I hope! And it's possible that some boards worked better than others.) The host worked just fine when I tested it many months ago. The only wiring issues I ran into were with the peripheral controller, specifically that the D+ pullup wasn't behaving (possibly related to a hardware pin muxing bug, for which rc5 has the workaround) and that lacking a VBUS IRQ, there was no way to gate the 48MHz clock (bad interactions with PM). Schematics might have helped resolve those issues. - Dave ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
