Beagleboard B and C rev have exactly the same limitation, OHCI is currently not functional, only EHCI -- hence high speed only. I'm guessing you have a Beagleboard xM, those include an onboard hub to work around this issue. Steve > So this is strange.

I don't see that showing up here, so I think it's not reading the pins right to go to 12Mb mode. I noticed that on one of your boot up lines you were telling it to only use the old method of finding USB devices. Was that for a reason? We're trying a hub now just to check power. This will also rule out the pin negotiation thing since the hub will proxy that for us. >>>> >>>> Just wondering about the old vs new method. >>>> >>>> Steve >>>> >>>> -- >>>> Steve Modica >>>> CTO - Small Tree Communications >>>> www.small-tree.com >>>> phone: 651-209-6509 ext 301 >>>> mobile: 651-261-3201 >>>> >>>> >>>> >>>> >>>> >>>> >>>> >>>>_____________________________________________ >>>> Create and publish websites with WebMatrix >>>> Use the most popular FREE web apps or write code yourself; >>>> WebMatrix provides all the features you need to develop and >>>> publish your website. http://p.sf.net/sfu/ms-webmatrix-sf >>>>_____________________________________________ >>>> gumstix-users mailing list >>>> gum...@li... >>>> https://lists.sourceforge.net/lists/listinfo/gumstix-users >>>> >>> >>> -- >>> Steve Modica >>> CTO - Small Tree Communications >>> www.small-tree.com >>> phone: 651-209-6509 ext 301 >>> mobile: 651-261-3201 >>> >>> >>> >>> >>> >>> >>> >>>_____________________________________________ >>> Create and publish websites with WebMatrix >>> Use the most popular FREE web apps or write code yourself; >>> WebMatrix provides all the features you need to develop and >>> publish your website. http://p.sf.net/sfu/ms-webmatrix-sf >>>_____________________________________________ >>> gumstix-users mailing list >>> gum...@li... >>> https://lists.sourceforge.net/lists/listinfo/gumstix-users >>> >> > > -- > Steve Modica > CTO - Small Tree Communications > www.small-tree.com > phone: 651-209-6509 ext 301 > mobile: 651-261-3201 > > > > > > >_____________________________________________ Create and publish websites with WebMatrix Use the most popular FREE web apps or write code yourself; WebMatrix provides all the features you need to develop and publish your website. http://p.sf.net/sfu/ms-webmatrix-sf_____________________________________________ gumstix-users mailing list gum...@li... https://lists.sourceforge.net/lists/listinfo/gumstix-users |
