Abstract: A device to be utilized for testing a program is connected to a device host operating in a service provider network via a peripheral bus. A network connection is established between a testing host, which might be a virtual machine, and the device host using a peripheral-bus-over-network-protocol. A secure network connection is established between the developer computing device and the testing host. A network port utilized by a debugging client application executing on the developer computing device is forwarded to the testing host over the secure network connection. Data packets generated by the debugging client application executing on the developer computing device are forwarded to a debugging server application execution on the testing host. Peripheral devices (e.g. the requested device) accessible to the testing host can then be utilized by the developer computing device for testing execution of the program as if the device were locally connected thereto.
