Starting with Windows 8 you can implement some Microsoft-specific USB extensions (0xee string descriptor and one type=vendor recipient=device control request) to make WinUSB bind and load to the device automatically within milliseconds without .inf .cat .sys files, device drivers, or user prompts. It can also be made to work on XPsp2 and later, with a preparatory one-time driver install. Once WinUSB is in place libusb can be used without risk for conflicts and without any system settings. Would then use a very simple TCP server that proxies GDB communication to the device. User experience on all systems becomes: Plug in device Double click GDB server icon => Done The only way to do something better is IMO with a device that joins an existing network, as opposed to one that creates a new network. The Carambola hardware is really a good fit for that type solution. USB could be used for power supply, while GDB communication uses wifi. If OpenOCD already interfaces Linux gpio to bitbang JTAG then the entire software development effort is less than 10 hours. //Peter ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
