Re: Blacklisting in-kernel drivers

I have done something similar before.   Perhaps let me explained my situation.

Linux have its default list of USB mouse drivers (well known VID/PID)
which it will load during bootup.   And so after plugging in my mouse,
and then using a userspace program to call libusb_claim_interface(), I
cannot claimed the interface because of a previously loaded mouse
driver.   (this is because the newly loaded mouse shared the same
VID/PID as the default kernel loaded driver)   So I used
libusb_detach_kernel_driver() to detach the kernel driver, and then
libusb_claim_interface() again to take control of the mouse.   From
thereon, the program can go into a polling loop to accept all input
from the USB devices via libusb_interrupt_transfer() etc....APIs.
Not sure if u have the same situation?

Thanks.
