There's an experimental out-of-tree driver available at http://cpm2usb.sourceforge.net/ The code is outdated and doesn't work, but that's a starting point. If I remember correctly, CPM2 USB host support requires the host to create SOF packets in software. High system loads will probably mess the bus up. A colleague of mines was told by Freescale to use an external USB controller instead of the MPC8248 bundled one. -- Laurent Pinchart CSE Semaphore Belgium Chaussée de Bruxelles, 732A B-1410 Waterloo Belgium T +32 (2) 387 42 59 F +32 (2) 387 42 75
