Dual boot behavior
By default, the AnywhereUSB Plus device stores two copies of firmware in two flash memory banks:
n
The current firmware version that is used to boot the device.
n
A copy of the firmware that was in use prior to your most recent firmware update.
When the device reboots, it will attempt to use the current firmware version. If the current firmware
version fails to load after three consecutive attempts, it is marked as invalid and the device will use
the previous firmware version stored in the alternate memory bank.
If the device consistently looses power during the boot process, this may result in the current
firmware being marked as invalid and the device downgrading to a previous version of the firmware.
As a result of this behavior, you can use the following procedure to guarantee that the same firmware
is stored in both memory banks:
ÉWebUI
