  2. Rebooting the computer also has the same effect. The driver is correctly installed, and the registry contains USB VID and PID entries that correctly point to it, but the device itself is simply not showing as present. The computer and USB device are packaged together in a cabinet, so it is not practical to unplug the device and reattach it.

Then I used Window Update to install all available Windows 7 updates, removed the Epson printer, reconnected the USB cable, and rebooted the computer. Again, Windows installed the ESC/P-R driver, which it says is the latest available. I will give up and just not use the scanner if I can't get this resolved. This software suite and driver help you setup the printer for PC running on the following Microsoft Windows Operating Systems: Vista (32/64-bit), 7 (32/64-bit), 8(32/64-bit), 8.1 (32/64-bit), Server 2003 (32/64-bit), Server 2008 (32/64-bit), 2008 R2 and Server 2012.

Tablet and phone firmware can vary between geographical markets for a given make and model of a device. The compatibilities presented below represent the results of LAVA’s testing of North American firmware unless indicated otherwise. LAVA recommends testing before large-scale deployments to ensure successful operation.

The Samsung Tablet requires the installation of the LAVA Tablet Manager (LTM) application, which is provided to the STS-RBM and eSTS integrator. The installation process requires a brief WiFi connection for a one-time activation of the Samsung KNOX license. The KNOX license does not require an additional fee.

The LTM Service has been verified in devices in the test summary with the STS-RBM, STS-**, and eSTS products as of January 2018. LAVA only has access to models from the Canadian market and some U.S. models for internal testing. A tablet integrator must perform a verification of the tablet model and build targeted for their application. LAVA will assist in the testing of other tablets provided a sample tablet is made available. The sample tablet must be delivered with the intended build already installed.

The tablet features used by the LAVA products are not universal across the Samsung Tablet line. Samsung tailors the tablet firmware to a world region or country. Tablet versions created by Samsung for mobile carriers do not behave the same as the standard products. You must verify the behavior of the model of tablet and firmware build to be used before committing to any deployment.

The Power-over-Ethernet (PoE) models require a suitable Network Switch with PoE support. A non-PoE Network Switch can use a PoE Power Injector for each port to operate with a PoE capable STS-RBM device. A PoE Power Injector is a standard add-on available from many Network Switch vendors.

STS-RBM/eSTS/nSTS models without PoE require a USB Power Supply with a Micro USB-B receptacle. The Wall/USB Charger provided with the tablet is an ideal choice for use with the LAVA product.

Description of Notes from the Test Summary
1The tablets issue a beep when the battery modulation changes from the discharging to charging state on most tablets. The newer tablets allow the “Charging sound” to be disabled within the Sound menu. Older tablets can lower the system volume if sound support is not required.
2The North American versions of the Tab E 9.6” tablet have been tested..

Problems have been using reported with U.K. Android 4.x.x versions of the tablet used with STS-** devices.

The U.K. Android builds have not been tested with eSTS and STS-RBM products.

3Requires tablet connection cable be no longer than 19” (50 cm).
4The SM-T377W was tested with build MMB29K.T377WVLU0APC3.

The unit tested was a Canadian model, not tied to a carrier.

5The SM-T377V was tested with build MMB29K.T377VVRU1BPD6.

Earlier builds do not work with the STS-RBM, eSTS devices, or any STS-** device.

The unit tested was a U.S.Verison model.

6The Tab A 10.1″ tablet briefly disconnects attached USB accessories each time the battery modulation changes from charging to discharging. This side effect has the benefit of periodically refreshing the internal resources used by the device. Using a wider set of modulation thresholds will minimize the impact of this behavior on the user.
7The Tab A 10.1″ measure in December of 2016 could require approximately 1.5 amperes during SimulCharge operation. After allowing for the power requirements of the LAVA hardware, about 0.15 to 0.2 amperes is available for user-provided USB accessories.
8The SM-T377P was tested with a special pre-release build of the firmware tested in August 2017.

Earlier versions charged at a very slow rate.

9The initial release of Android 7.0 for the Tab A 10.1” (SM-T580) was not compatible with the enhanced features of the eSTS product due to problems in the Samsung KNOX Standard SDK. The tablet received the update to Android 7.0 in early-2017. The bug was fixed only for select markets in the final weeks of 2017. The North American models are known to be fixed. Only select countries in Europe received the update. Please contact LAVA for additional details. All versions of the tablet tested, work with nSTS-** and original STS-** products.
10The Tab E 8.0” AT&T (SM-T377A) model has been tested with Android 6.0.1. As of December 2017 the most recent version of firmware for the tablet is based on Android 6.0.1. The firmware build MMB29K.T377AUCU2APJ2 was fully compatible with the STS-RBM and eSTS product family.
11The Tab E 8.0” T-Mobile (SM-T377T) model has been tested with Android 7.1.1. The Android 7.1.1 (build NMF26X.T377TUVU1BQI5) is fully compatible with the eSTS, nSTS, and original STS-** product family.

The tablet comes with Android 6.0.1 (build MMB29K.T377TUVS1APL1) out of the box.

The Android 6.0.1 firmware is not compatible with the eSTS, nSTS, or STS-** product family and must be updated to Android 7.1.1.

12The Tab S2 (SM-T810) and related models received an update to Android 7.0 in the spring of 2017. The Android 7.0 update introduced a bug in the Samsung KNOX Standard SDK which resulted in the tablet no longer being compatible with the enhanced features of the STS-RBM and eSTS product family.

The bug is known to have been fixed in at least one 8.0” version of the Tab S2 family (using build NRD90M.T710XXU2DQI6); however the majority of the models never received the update.

All known versions of the tablet continue to work with nSTS-** and original STS-** products.
