have you checked with Cypress on the driver? I'd be surprised if they didnt have one already.  --- On Mon, 6/2/08, Herbert Graf <hgraf@email.com> wrote: From: Herbert Graf <hgraf@email.com> Subject: [EE] USB2 solutions - Cypress FX2 To: "Microcontroller discussion list - Public." <piclist@mit.edu> Date: Monday, June 2, 2008, 1:10 PM Hello all, I've been looking into USB2 solutions. I need to create a high speed USB device that'll connect to a linux box. I've been looking into the options have have decided to try out the Cypress EZ-USB FX2 parts. I was wondering if anyone here has any experience with developing for those parts? In the end I'll only need to have one isochronous EP. Also, anybody have any pointers for writing a USB driver for Linux? I've got some resources but wouldn't mind fielding some recommendations.
