USB Devices Pre-Configuration For KVM Switch

A computer program product in a computer readable storage medium for configuring devices, the computer program product comprising:

• instructions for retrieving device information for a plurality of devices from an object data manager;
• instructions for determining whether a keyboard-video-mouse environment exists;
• responsive to determining the keyboard-video-mouse environment does not exist, instructions for configuring each device in the plurality of devices to one of an available state or a defined state, wherein the available state indicates an available device, and wherein the defined state indicates an unavailable device;
• and
• responsive to determining the keyboard-video-mouse environment exists, instructions for configuring each device in the plurality of devices to the available state, wherein the instructions for configuring each device in the plurality of devices to the available state further comprises:
• instructions for requesting a list of all enumerated devices, wherein the list of all enumerated devices consists of all real devices;
• instructions for determining whether a first device in the plurality of devices is in the list of all enumerated devices;
• and
• responsive to the first device in the plurality of devices not being in the list of all enumerated devices, instructions for adding a pseudo first device to the list of all enumerated devices to form a modified list of all enumerated devices.

An apparatus for configuring devices in a keyboard-video-mouse environment, the apparatus comprising:

• a keyboard-video-mouse switch;
• a first computer;
• a second computer;
• a keyboard;
• a monitor;
• a mouse;
• and
• a device driver, wherein the device driver retrieves device information for a plurality of devices from a device tree;
• determines whether a keyboard-video-mouse environment exists;
• responsive to determining the keyboard-video-mouse environment does not exist, configures each device in the plurality of devices to one of an available state or a defined state, wherein the available state indicates an available device, and wherein the defined state indicates an unavailable device;
• responsive to determining the keyboard-video-mouse environment exists, configures each device in the plurality of devices to the available state, wherein the device driver configures each device in the plurality of devices to the available state and further requests a list of all enumerated devices, wherein the list of all enumerated devices consists of all real devices;
• determines whether a first device in the plurality of devices is in the list of all enumerated devices;
• responsive to the first device in the plurality of devices not being in the list of all enumerated devices, adds a pseudo first device to the list of all enumerated devices to form a modified list of all enumerated devices;
• determines whether a second device in the plurality of devices is in the modified list of all enumerated devices;
• and responsive to the second device in the plurality of devices not being in the modified list of all enumerated devices, adds a second pseudo device to the modified list of all enumerated devices.
