Toshiba WT8-B - Manual (Page 51)

The AC adaptor should not be disconnected with the "USB Data and
Charge Y-Cable" if it is connecting with USB device and tablet at the
same time. If the USB device works with USB bus power, which
comes from "USB Data and Charge Y-Cable", the disconnection of AC
adaptor would cause power loss. Even if the USB device has its own
power source, the device will stop around 60 miliseconds because
USB controller would detect with “no bus power” due to sudden
disconnection with AC adaptor. The disconnection may cause data
loss and thus Windows may detect error and start data recovery.
Charging the tablet via connecting the "USB Data and Charge Y-
Cable" will need 1.5A for charging, and if a USB device is connected
to the tablet, it will need 2A for charging. In this case, when charging
from PC’s USB port which only supports 1A, the power supply may
stop working.
When using “USB Data and Charge Y-Cable”, there might be a
possibility that power charging to the tablet might not work. Possibility
will get higher if the USB device connected with the “USB Data and
Charge Y-Cable” is non-standard USB 2.0 device.
Tablets other than TOSHIBA WT10-A and TOSHIBA WT8-B cannot
support "USB Data and Charge Y-Cable".
