* For Interrupt transfers USB_MAX_TEMP_INT_TD Transfer descriptor are available. They
* will be inserted after the appropriate (depending the interval setting) skeleton TD.
* If an interrupt has been detected the dev->irqhandler is called. The status and number
- * of transfered bytes is stored in dev->irq_status resp. dev->irq_act_len. If the
+ * of transferred bytes is stored in dev->irq_status resp. dev->irq_act_len. If the
* dev->irqhandler returns 0, the interrupt TD is removed and disabled. If an 1 is returned,
* the interrupt TD will be reactivated.
