I see this is part of a call to usb_fill_int_urb(). Since the device always runs at full speed, the value should be a time interval given in frames, i.e., milliseconds. If you intend the URB to fire every 250ms, then the value should be 250 -- not HZ/4, which can vary considerably among platforms. Alternatively, you could copy the value from the endpoint's descriptor.
