ioctl returning -32 ENODEV

Hello all,

I'm writing an app like USBHSET but for linux, when I issue some kind
of control msg (which is an ioctl()) it's returning -32 ENODEV. But
when I issue usb_reset() (another ioctl()) it's working fine.

Where can I find the definition for ioctl() and when does it returns ENODEV???

thanks
