If you're asking about U-Boot support, the list is u-b...@lists.denx.de Be sure to mention what version of U-Boot you're using, and that you're using a recent U-Boot. Also, don't top post or post the same thing twice. If you're using U-Boot from the Freescale SDK rather than from upstream, then instead get support from supp...@freescale.com or https://community.freescale.com/ It might be a good idea to go that route regardless, given that this sounds like it may be a hardware compatibility issue. I don't think there is a separate host controller or driver for USB 1.1 (or lower speed USB 2.0) devices on p4080 (though this is common on PCs). -Scott > > Thank you > Regards > ruchika > > > On 2/19/2014 11:55 PM, Ruchika wrote: > > Hi, > > I've been trying to understand why the uboot code is unable to work with > > USB1.1 devices. > > On a USB analyzer: > > I notice on an analyzer that there are no SOF or IN tokens seen on the > > bus at all.
