Hi, I've got a question regarding misc/usbtest.c I'm trying to write a userland test program which issues usbtest ioctl operation and utilize some of those 17 operations defined in misc/usbtest.c. I looked through the misc/usbtest.c, and found out that you can specify vendor/product as module params so that the usbtest module gets loaded for whatever the device you want even if that device is not on the device_id table of misc/usbtest.c. But it seems you first have to unload the class driver if the default one is already loaded. What if the class driver is not a kernel module, and is statically linked to linux kernel ? Since it is not a module, I can not rmmod it, and as a result, I am unable to load the usbtest. Is there any way I can load it in this situation without re-compiling the kernel ? Any comments would be helpful.
