Property Description
Property OID	1.2.2.2.1.1 / 0x010202020101
Name	Reduce Power During USB Suspend
Description	The device uses this property to determine whether it should reduce its power consumption when a USB host directs it to suspend. If this property is set to Disabled, the device will not have a USB compliant current draw when suspended, which, for example, allows it to continue to turn on LEDs and the display if present. To activate changes made to this property, the device must be reset or power cycled.
Securing Key	None
Min. Len (b)	1
Max. Len (b)	1
Data Type	Binary
Valid Values	0x00 = Disabled 0x01 = Enabled
Default	0x01

## Table - Property 1.2.2.2.1.2 USB Configuration Type


Property Description
Property OID	1.2.2.2.1.2 / 0x010202020102
Name	USB Configuration Type
Description	The device uses this property to determine if it should behave as a USB HID device or an USB iAP2 device. USB HID devices can communicate with most hosts except for Apple hosts. USB iAP2 devices can communicate to Apple hosts like iPads and iPhones. The behavior affects USB enumeration and communications. To activate changes made to this property, the device must be reset or power cycled.
Securing Key	None
Min. Len (b)	1
Max. Len (b)	1
Data Type	Binary
Valid Values	0x00 = HID only 0x01 = iAP2 only 0x02 = autodetect (iAP2 with HID fallback) The autodetect option can allow a device to work with iAP2 hosts and HID hosts. With this option, every time the device is attached to a USB host it will first enumerate as an iAP2 device, if the device does not receive an iAP2 initialization sequence response from the host within 2 seconds the device will perform a soft USB detach from the host and then a soft USB attach and next enumerate as a USB HID device.
Default	0x02

--- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://developer.magtek.com/hardware/card-readers/mms-dyna-devices/dynaprox/documents/programmers-manuals/programmers-manual-commands/configuration/device-settings/usb-settings.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
