Can't we even have that under some CONFIG_USB_TEST kinda thing ? You might not need a new host controller driver (depending on whether or not you want to continue using other USB devices normally while running the test -- to be safe you probably would want to avoid this), but you would need to make extensive changes to the USB core. In particular, to the hub driver and usbfs. > It would be really helpful to avoid having to use Windows for those kinds of > tests. I sympathize. However, if people have gone to all the trouble of writing new kernel drivers for Windows specifically for use with USBCV, then it seems reasonable that the same amount of kernel-intensive work would be required to run those tests under Linux.
