very reassuring :-) lemme clarify, it's probably not as bad as it sounds... > If you really want to do this, try the USB Serial Console config option, > that will do what you want to do (I think, you are talking kernel debug > console, right?) Actually, I was thinking about using the module to debug some code on the EZ-USB chip with printf(). Using SDCC, I redefined putchar() to write to a string descriptor, but I would rather be able to just write to a bulk endpoint that could be read on the Linux host. (This is where it would be handy for usbfs to export endpoints as read/write files.) With the generic usb-serial driver, I figured I could just fire up Minicom (or cat, even) on /dev/ttyUSB0 and capture all of the printf output. (String descriptors only give you 255 characters at a time, I think.) If that's not what the generic usb-serial driver lets one do, well, there might be a documentation patch coming your way :-) -- Charles Lepple <[EMAIL PROTECTED]> http://www.ghz.cc/charles/ ------------------------------------------------------- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.
