Abstract

In one embodiment, a remote access session may be established between a first computer and a second computer. In response to detecting a device in low-level local communication with the first computer via a first local communication port of the first computer, the low-level local communication at the first local communication port may be intercepted and transmitted to the second computer via the remote access session. Then, the low-level local communication may be injected to a second local communication port of the second computer, wherein the second computer responds to the low-level local communication as though the device were located at the second local communication port of the second computer. For example, the device may be configured to autoconnect with the second computer via the remote access session when the device is connected to the first computer.

2. The method as in claim 1, further comprising:

configuring the device to autoconnect with the second computer via the remote access session upon connection of the device to the first computer.

3. The method as in claim 1, further comprising:

prompting for a password to establish the remote access session in response to detecting the device is connected to the first computer and determining that the device is configured to autoconnect with the second computer upon connection of the device to the first computer.

4. The method as in claim 1, further comprising:

performing an autosync operation between the device and a corresponding file folder of the second computer.

5. The method as in claim 1, further comprising:

sending a second low-level local communication from the second computer to the second local connection port;

intercepting the second low-level local communication at the second local communication port;

transmitting the second low-level local communication to the first computer via the remote access session; and

injecting the second low-level local communication to the first local communication port of the first computer, wherein the first local communication port transmits the second low-level local communication to the device as though the second low-level local communication were sent from the first computer.

6. The method as in claim 1, wherein the first computer is a local computer and the second computer is a remote computer.

7. The method as in claim 1, wherein the second computer is a local computer and the first computer is a remote computer.

8. The method as in claim 1, wherein the first and second local communication ports are selected from a group consisting of:

a universal serial bus (USB) port, and a wireless personal area network port.

9. The method as in claim 1, wherein the device is selected from a group consisting of:

a storage device, a music player, a personal digital assistant (PDA), and a phone.

10. The method as in claim 1, wherein the low-level local communication comprises messages having a format and content defined by a protocol suitable for communication between the local communication port and the device.

11. A first computer, comprising:

a first local communication port;

a network interface;

a processor; and

a memory configured to store one or more software processes executable by the processor, the one or more software processes including

a local communication port driver configured to

provide low-level local communication between the first computer and a device connected to the first computer via the first local communication port, and

a remote access service configured to

detect the device is connected to the first computer and is in low-level local communication with the first computer,

determine that the device is configured to autoconnect with a second computer upon connection of the device to the first computer,

establish a remote access session between the first computer and the second computer via the network interface in response to the device being connected to the first computer and configured to autoconnect with the second computer upon connection of the device to the first computer, wherein the remote access session is an online collaborative computing session,

intercept the low-level local communication at the first local communication port, and

transmit the low-level local communication to the second computer via the remote access session, to enable the second computer to respond to the low-level local communication as though the device were located at a second local communication port of the second computer.

12. The first computer as in claim 11, wherein the first communication port is selected from a group consisting of:

a universal serial bus (USB) port, and a wireless personal area network port.

13. The first computer as in claim 11, wherein the device is selected from a group consisting of:
