Parameter Description
(str)
USB startup configuration
This parameter can be used to control the USB startup enumeration. Any change takes effect the next time the
ME is re-enumerated.
Parameter is global for all interfaces, non-volatile and will not be reset by AT&F.
“MS“
On power-up the HC25 enumerates as USB mass storage device.
The Product ID for the mass storage device is 0x0041.
The mass storage can be used with standard drivers typically integrated in
most operating systems.
“MdmNet“ (D)
“Mdm“
When you are finished using the mass storage you can easily switch over to
composite device operation. To do so, use the Eject option. Under Windows
XP, for example, open the Windows Explorer, right-click the "Removable Disk"
drive and select "Eject". This deactivates the mass storage and, at the same
time, activates the USB composite communication device without any need to
restart the ME. Parameter determines the type of USB composite
communication device to activate when the mass storage is ejected.
The option "Safely Remove the Hardware" commonly used for USB devices
under Windows terminates the mass storage function without activating the
composite device function.
On power-up the HC25 enumerates as USB composite communication device
with the following virtual ports: modem port, application port (VCOM) and wireless
network adapter (NET).
The Product ID for this enumeration is 0x0040.
The "MdmNet" enumeration mode is intended for PC based Windows operating
systems and is fully supported by the HC25 USB driver package supplied
by Siemens for Windows XP and Windows Vista.
On power-up the HC25 enumerates as USB composite communication device
supporting modem port and application port (VCOM), but no wireless network
adapter (NET).
The Product ID for this enumeration is 0x0047.
The "Mdm" enumeration mode is not supported by the HC25 USB driver package
supplied by Siemens for Windows XP and Windows Vista.
Before selecting "Mdm" carefully read the information provided in [7]. See also
notes below.
(str)
Maximum power
Maximum power consumption of the USB device from the USB bus. This parameter is reported to a USB host
as part of the USB enumeration.
Only even values are supported. Odd values are truncated.
Any change of this parameter becomes active with the next device enumeration.
Parameter is global for all interfaces, non-volatile and will not be reset by AT&F.
0...10 (D) ...500 Device maximum power consumption in mA
(str)
Power source
This parameter can be used to specify the power source. Any change of this parameter becomes active with the
next device enumeration.
Parameter is global for all interfaces, non-volatile and will not be reset by AT&F.
“BUS“
Device enumerates as bus powered device.
“SELF“ (D)
Device enumerates as self powered device.
