You must use usb_kill_urb() here.

+ if (!serial)
+ return;

+ dbg("%s - port %d", __FUNCTION__, port->number);

If serial->dev can be NULL, you must not use iuu_led unconditionally.
+static int iuu_uart_on(struct usb_serial_port *port)

A simple 4 will do.

+ if (!tmp)

Memory leak in error case
+ if (tmp->len > 0) {

+ if (curpos + tmp->len > 256) {
+ kfree(tmp);

What is -1 supposed to mean?
+ if (priv->write_busy)
+ return -1;
+
+ tmp = kmalloc(sizeof(struct iuu_buffers), GFP_KERNEL);
+ if (!tmp)
+ return -EIO;
+
+ priv->write_busy = 1;
This is a race condition. More than one task can succeed the test and proceed.
