Sounds good. I was reading here (https://lwn.net/Articles/434833/) about the dev_dbg() function. Any ideas what I should do to enable this type of debugging on Debian Linux? I should mention that I've never built the kernel from source before. :) Thanks, -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
