-/**********************************************************************
- * How it works:
- * -------------
- * The framelist / Transfer descriptor / Queue Heads are similar like
- * in the linux usb_uhci.c.
- *
- * During initialization, the following skeleton is allocated in init_skel:
- *
- *         framespecific           |           common chain
- *
- * framelist[]
- * [  0 ]-----> TD ---------\
- * [  1 ]-----> TD ----------> TD ------> QH -------> QH -------> QH ---> NULL
- *   ...        TD ---------/
- * [1023]-----> TD --------/
- *
- *              ^^             ^^         ^^          ^^          ^^
- *              7 TDs for      1 TD for   Start of    Start of    End Chain
- *              INT (2-128ms)  1ms-INT    CTRL Chain  BULK Chain
- *
- *
- * Since this is a bootloader, the isochronous transfer descriptor have been removed.
- *
- * Interrupt Transfers.
- * --------------------
- * For Interupt 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
- * dev->irqhandler returns 0, the interrupt TD is removed and disabled. If an 1 is returned,
- * the interrupt TD will be reactivated.
- *
- * Control Transfers
- * -----------------
- * Control Transfers are issued by filling the tmp_td with the appropriate data and connect
- * them to the qh_cntrl queue header. Before other control/bulk transfers can be issued,
- * the programm has to wait for completion. This does not allows asynchronous data transfer.
- *
- * Bulk Transfers
- * --------------
- * Bulk Transfers are issued by filling the tmp_td with the appropriate data and connect
- * them to the qh_bulk queue header. Before other control/bulk transfers can be issued,
- * the programm has to wait for completion. This does not allows asynchronous data transfer.
