+.. method:: USB_HID.recv(data, \*, timeout=5000)
+
+   Receive data on the bus:
+   
+     - ``data`` can be an integer, which is the number of bytes to receive,
+       or a mutable buffer, which will be filled with received bytes.
+     - ``timeout`` is the timeout in milliseconds to wait for the receive.
+   
+   Return value: if ``data`` is an integer then a new buffer of the bytes received,
+   otherwise the number of bytes read into ``data`` is returned.
+
 .. method:: USB_HID.send(data)
