Cancels a device insertion hook (the hook request will be replied to with return value -7022). The input buffer is probably used to specify the VID/PID. {{check}}

Cancels a device insertion hook (the hook request will be replied to with return value -7022). The input buffer is the ID given in the unique output vector of ioctlv 30.

Returns IPC_EINVAL if input buffer was nullptr. Otherwise, IPC_SUCCESS is returned if there was no hook;

Returns IPC_EINVAL if input buffer was nullptr. Otherwise, IPC_SUCCESS is returned if there was no hook;

if there was a pending hook, the return value of <code>IOS_ResourceReply(pending_hook, -7022)</code> is used.

if there was a pending hook, the return value of <code>IOS_ResourceReply(ioctlv_30_request, -7022)</code> is used.
