++FIX - Toggle Error nach STALL - Einfacher Workaround - Nun werden Massenspeicherpartitionen erkannt!
++AVM_POWERMETER - USB Energiemonitor Support.

++ ** MODULES : IFX USB sub-system Host and Device driver
++ ** SRC VERSION : 1.0
++ ** DATE : 1/Jan/2009
++ ** AUTHOR : Chen, Howard
++ ** DESCRIPTION : This file contains the structures, constants, and interfaces for
++ ** the Host Contoller Driver (HCD).
++ **
++ ** The Host Controller Driver (HCD) is responsible for translating requests
++ ** from the USB Driver into the appropriate actions on the IFXUSB controller.
++ ** It isolates the USBD from the specifics of the controller by providing an
++ ** API to the USBD.

++ \brief This function trigger a data transfer for a host channel and
++ starts the transfer.
++
++ For a PING transfer in Slave mode, the Do Ping bit is set in the HCTSIZ
++ register along with a packet count of 1 and the channel is enabled. This
++ causes a single PING transaction to occur. Other fields in HCTSIZ are
++ simply set to 0 since no data transfer occurs in this case.
++
++ For a PING transfer in DMA mode, the HCTSIZ register is initialized with
++ all the information required to perform the subsequent data transfer. In
++ addition, the Do Ping bit is set in the HCTSIZ register. In this case, the
++ controller performs the entire PING protocol, then starts the data
++ transfer.
++ \param _core_if Pointer of core_if structure
++ \param _ifxhc Information needed to initialize the host channel. The xfer_len
++ value may be reduced to accommodate the max widths of the XferSize and
++ PktCnt fields in the HCTSIZn register. The multi_count value may be changed
++ to reflect the final xfer_len value.

++
++ A URBD is linked to a EP Queue Head, which is entered in either the
++ isoc, intr or non-periodic schedule for execution. When a URBD is chosen for
++ execution, some or all of its transactions may be executed. After
++ execution, the state of the URBD is updated. The URBD may be retired if all

++ // buffer is used for the data stage of control transfers.
++ //transfer_dma When transfer_flags includes URB_NO_TRANSFER_DMA_MAP, the
++ // device driver is saying that it provided this DMA address,
++ // which the host controller driver should use in preference
++ // to the transfer_buffer.
++ //transfer_buffer_length How big is transfer_buffer. The transfer may be broken
++ // up into chunks according to the current maximum packet size
++ // for the endpoint, which is a function of the configuration
++ // and is encoded in the pipe. When the length is zero, neither
++ // transfer_buffer nor transfer_dma is used.
++ //actual_length This is read in non-iso completion functions, and it tells
++ // how many bytes (out of transfer_buffer_length) were transferred.
++ // It will normally be the same as requested, unless either an error
++ // was reported or a short read was performed. The URB_SHORT_NOT_OK
++ // transfer flag may be used to make such short reads be reported
++ // as errors.
++ //setup_packet Only used for control transfers, this points to eight bytes of
++ // setup data. Control transfers always start by sending this data
++ // to the device. Then transfer_buffer is read or written, if needed.
++ //setup_dma For control transfers with URB_NO_SETUP_DMA_MAP set, the device

++ \brief This function does the setup for a data transfer for a host channel and

++ Slave mode, the caller must ensure that there is sufficient space in the

++
++ For an OUT transfer in Slave mode, it loads a data packet into the
++ appropriate FIFO. If necessary, additional data packets will be loaded in
++ the Host ISR.
++
++ For an IN transfer in Slave mode, a data packet is requested. The data
++ packets are unloaded from the Rx FIFO in the Host ISR. If necessary,
++ additional data packets are requested in the Host ISR.
++
++ For a PING transfer in Slave mode, the Do Ping bit is set in the HCTSIZ
++ register along with a packet count of 1 and the channel is enabled. This
++ causes a single PING transaction to occur. Other fields in HCTSIZ are
++ simply set to 0 since no data transfer occurs in this case.
++
++ For a PING transfer in DMA mode, the HCTSIZ register is initialized with
++ all the information required to perform the subsequent data transfer. In
++ addition, the Do Ping bit is set in the HCTSIZ register. In this case, the
++ controller performs the entire PING protocol, then starts the data
++ transfer.

++ \brief Attempts to halt a host channel. This function should only be called in
++ Slave mode or to abort a transfer in either Slave mode or DMA mode. Under
++ normal circumstances in DMA mode, the controller halts the channel when the
++ transfer is complete or a condition occurs that requires application
++ intervention.
++
++ In slave mode, checks for a free request queue entry, then sets the Channel
++ Enable and Channel Disable bits of the Host Channel Characteristics
++ register of the specified channel to intiate the halt. If there is no free
++ request queue entry, sets only the Channel Disable bit of the HCCHARn
++ register to flush requests for this channel. In the latter case, sets a
++ flag to indicate that the host channel needs to be halted when a request
++ queue slot is open.
++
++ In DMA mode, always sets the Channel Enable and Channel Disable bits of the
++ HCCHARn register. The controller ensures there is space in the request
++ queue before submitting the halt request.
++
++ Some time may elapse before the core flushes any posted requests for this
++ host channel and halts. The Channel Halted interrupt handler completes the
++ deactivation of the host channel.

++ ** FILE NAME : ifxusb_regs.h
++ ** PROJECT : IFX USB sub-system V3
++ ** MODULES : IFX USB sub-system Host and Device driver
++ ** SRC VERSION : 1.0
++ ** DATE : 1/Jan/2009
++ ** AUTHOR : Chen, Howard
++ ** DESCRIPTION : This file contains the data structures for accessing the IFXUSB core
++ ** registers.
++ ** The application interfaces with the USB core by reading from and
++ ** writing to the Control and Status Register (CSR) space through the
++ ** AHB Slave interface. These registers are 32 bits wide, and the
++ ** addresses are 32-bit-block aligned.
++ ** CSRs are classified as follows:
++ ** - Core Global Registers
++ ** - Device Mode Registers
++ ** - Device Global Registers
++ ** - Device Endpoint Specific Registers
++ ** - Host Mode Registers
++ ** - Host Global Registers
++ ** - Host Port CSRs
++ ** - Host Channel Specific Registers
++ **
++ ** Only the Core Global registers can be accessed in both Device and
++ ** Host modes. When the USB core is operating in one mode, either
++ ** Device or Host, the application must not access registers from the
++ ** other mode. When the core switches from one mode to another, the
++ ** registers in the new mode of operation must be reprogrammed as they
++ ** would be after a power-on reset.
