A device holder includes a base, a hinge, and an arm. The base includes a mounting feature configured to affix the device holder to a portable computer device, and the hinge is connected to the base. The arm is connected to the hinge and opposes the base. The arm is rotatable with respect to the base to change the device holder between a stowed configuration, when the arm is positioned alongside the base, and a deployed configuration, when the first arm is positioned away from the base. In addition, the device holder is configured to hold a peripheral device of the portable computer device when the device holder is in the deployed configuration.

An example operation may include one or more of receiving a data packet from a network controller, where the data packet is marked as valid based on a checksum calculated by the network controller, determining that the checksum generated by the network controller is in error based on a recalculation of the checksum of the data packet via a network layer, and transmitting the data packet from the network layer to the network controller with a notification that the checksum is in error.

A device case computer mouse includes a body including a cavity configured to attach the device case to a handheld computer, a motion sensor connected to the body, a battery connected to the body, and a charging port connected to the body and electrically connected to the battery, the charging port being configured to be connected to a case charging cable. Also included is a processor electrically connected to the battery and communicatively connected to the motion sensor, wherein the processor is configured to be communicatively connected to the handheld computer wirelessly and to a portable computer to transmit motion data from the motion sensor to the portable computer and to transmit input data from the handheld computer to the portable computer.
