* Addresses: because WUSB hosts have no downstream hubs, we can do a
* 1:1 mapping between 'port number' and device
* address. This simplifies many things, as during this
- * initial connect phase the USB stack has no knoledge of
+ * initial connect phase the USB stack has no knowledge of
* the device and hasn't assigned an address yet--we know
- * USB's choose_address() will use the same euristics we
+ * USB's choose_address() will use the same heuristics we
* use here, so we can assume which address will be assigned.
*
* USB stack always assigns address 1 to the root hub, so
