What specific data do you want to see be being returned here? The USB configuration data? Like you read from the binary usbfs file if you open and read from it? If so, then I have no objection to that, as long as you are taking data directly from the device and not parsing it at all in the kernel and passing it on to userspace. That's the only way we allow a "binary" file in sysfs. Look at the PCI file called "config" in sysfs and see if that is what you are looking for. thanks, greg k-h ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
