The "SmartDocs" bar can customize this page to show only the features present on a particular Zebra device.
OSX, MX and Android version information for a device can be found in the Android Settings panel or by querying the device through ADB, EMDK or the MX CSP. More info.
The USB Manager (UsbMgr) controls which USB functions can be used on the device.
Android devices generally have one or more Universal Serial Bus (USB) ports that can be used for various purposes. A given USB port could implement "Host" mode, which is used to connect various USB peripherals (e.g. mice, keyboards, USB storage devices) to the Android device. A given USB port could implement "Peripheral" mode, which is used to connect the Android device to a Host, such as a PC. A given USB port could implement On The Go (OTG) support, which can act in either "Host" or "Peripheral" mode, based on the cable connected.
Controls whether the use of USB module is allowed. Setting this parm would cause all of the USB features to be enabled or disabled.
Parm Name: UsbModuleUsage
| Option | Name | Description | Note | Requires |
|---|---|---|---|---|
| 0 | Do not change | This value (or the absence of this parm from the XML) causes no change to settings on the device; any previous setting is retained. |
OSX: 1.3+ MX: 4.2+ |
|
| 1 | Enable | Allows usage of the USB module. |
OSX: 1.3+ MX: 4.2+ |
|
| 2 | Disable | Prevents usage of the USB module. |
OSX: 1.3+ MX: 4.2+ |
Controls whether the use of USB External Storage devices will be allowed. When allowed, a USB External Storage device could have to be connected via a USB port that supports Host mode or via an OTG USB port with an OTG adapter cable or OTG compliant storage device. Use of USB External Storage could represent a security risk since it could be used as a path to extract sensitive data from a device or to inject unwanted data or applications into a device.
Shown if: The "USB Module Usage" value is not "Disable"
Parm Name: UsbExternalStorageUsage
| Option | Name | Description | Note | Requires |
|---|---|---|---|---|
| 0 | Do not change | This value (or the absence of this parm from the XML) causes no change to settings on the device; any previous setting is retained. |
OSX: 4.1+ MX: 4.2+ |
|
| 1 | Enable | This value will cause use of USB External Storage to be allowed. |
OSX: 4.1+ MX: 4.2+ |
|
| 2 | Disable | This value will cause use of USB External Storage to be prevented. |
OSX: 4.1+ MX: 4.2+ |
Controls whether Android Debug Bridge (ADB) mode can be enabled on the device. When allowed, a PC could be connected to the device through a USB port that supports Peripheral mode or by using a USB "on the go" cable. Once connected, an ADB command line tool could allow communication between the PC and the Android device for copying files, installing apps, running shell commands, etc. Use of ADB could represent a security risk since it could be used as a path to extract sensitive data from a device, to inject unwanted data or applications into a device, or to remove or modify the operation of important applications on a device.
Shown if: The "USB Module Usage" value is not "Disable"
Parm Name: UsbADBUsage
| Option | Name | Description | Note | Requires |
|---|---|---|---|---|
| 0 | Do not change | This value (or the absence of this parm from the XML) causes no change to settings on the device; any previous setting is retained. |
OSX: 1.3+ MX: 4.2+ |
|
| 1 | Enable | Allows ADB mode to be enabled on the device. |
OSX: 1.3+ MX: 4.2+ |
|
| 2 | Disable | Prevents ADB mode from being enabled on the device. |
OSX: 1.3+ MX: 4.2+ |
Controls whether the use of any direct method of accessing device storage from a PC via USB is allowed. This controls the use of USB Mass Storage (UMS), Media Transfer Protocol (MTP) and Picture Transfer Protocol (PTP). Does not control the use of ADB mode, which is controlled separately.
When these modes are allowed, a PC could be connected to the device via a USB port that supports Peripheral mode or using an "on-the-go" (OTG) USB port. Once connected, such a PC could browse exposed portions of the device file system, copy files to or from the device, delete files, etc. Use of these modes could represent a security risk since it could be used as a path to extract sensitive data from a device, to inject unwanted data or applications into a device, or to delete important information from a device.
Shown if: The "USB Module Usage" value is not "Disable"
Parm Name: UsbAllAccessDeviceStorageUsage
| Option | Name | Description | Note | Requires |
|---|---|---|---|---|
| 0 | Do not change | This value (or the absence of this parm from the XML) causes no change to settings on the device; any previous setting is retained. |
OSX: 4.1+ MX: 4.2+ |
|
| 1 | Enable | Allows access to device storage from a PC via USB. This value will also prevent other parms from being presented since individual modes cannot be controlled if all modes are being allowed. |
OSX: 4.1+ MX: 4.2+ |
|
| 2 | Disable | Prevents access to device storage from a PC via USB. This value will also prevent other parms from being presented since individual modes cannot be controlled if all modes are being prevented. |
OSX: 4.1+ MX: 4.2+ |
Controls access to the device as USB Mass Storage (UMS). When this mode is allowed, a PC can be connected to the device through a USB port that supports Peripheral mode or using an "on-the-go" (OTG) USB port. Once connected, such a PC could browse exposed portions of the device file system, copy files to or from the device, delete files, or even format an entire storage volume. Use of this mode could represent a security risk since it could be used as a path to extract sensitive data from a device, to inject unwanted data or applications into a device, or to delete important information from a device.
Note: This feature is not supported on devices running Android 5.x Lollipop or later.
Shown if: The "USB Module Usage" value is NOT "Disable" AND the "Access device storage from PC via USB" value is NEITHER "Enable" nor "Disable"
Parm Name: UsbUMSAccessDeviceStorageUsage
| Option | Name | Description | Note | Requires |
|---|---|---|---|---|
| 0 | Do not change | This value (or the absence of this parm from the XML) causes no change to settings; any previously selected setting is retained. |
OSX: 4.1 - 5.4 NOT IN OSX 6.0 OR HIGHER MX: 4.2+ |
|
| 1 | Enable | Enables access to device storage from a PC via USB UMS. |
OSX: 4.1 - 5.4 NOT IN OSX 6.0 OR HIGHER MX: 4.2+ |
|
| 2 | Disable | Disables access to device storage from a PC. |
OSX: 4.1 - 5.4 NOT IN OSX 6.0 OR HIGHER MX: 4.2+ |
The is the On/Off switch for the use of Media Transfer Protocol (MTP) on the device. When this mode is enabled, a PC can connect to the device through a USB port that supports Peripheral mode or the "on-the-go" specification. Once connected, such a PC could browse exposed portions of the device file system, copy files to or from the device, or delete files. Use of this mode could represent a security risk since it could be used as a path to extract sensitive data from a device, to inject unwanted data or applications into a device, or to delete important information from a device.
Shown if: The "USB Module Usage" value is not "Disable" *AND* the "Access device storage from PC via USB" value is not "Enable" or "Disable"

|
| 1 | Enable | This value will cause access to the device storage from a PC via USB MTP to be allowed. |
OSX: 4.1+ MX: 4.2+ |
|
| 2 | Disable | This value will cause access to the device storage from a PC via USB MTP to be prevented. |
OSX: 4.1+ MX: 4.2+ |
This is the On/Off switch for the use of Picture Transfer Protocol (PTP) on the device. When this mode is enabled, a PC can connect to the device through a USB port that supports Peripheral mode or the "on-the-go" specification. Once connected, such a PC could browse exposed portions of the device file system, copy files to or from the device, or delete files. Use of this mode could represent a security risk since it could be used as a path to extract sensitive data from a device, to inject unwanted data or applications into a device, or to delete important information from a device.
