Hi,
While I'm searching how to use the extra buttons in Kensington Slimblade
Trackball, I made a patch for myself based on the linux driver.
I confirmed it works as intended. However, I have no experience with the FreeBSD
kernel and I'm not sure that I modified it in a correct way. -- especially,
I don't know should I use usb_quirks?
Can somebody check the attached diff file so that I can send problem report?
Thanks.
