Indeed, a while back I searched long and hard for such a thing and didn't come up with anything, I concluded that they were either fictional, ancient and unavailable or something one needed to build for oneself with a soldering iron :-/ I just had another look and things seem more promising, the "Net chip USB debug link" in https://www.kernel.org/doc/Documentation/x86/earlyprintk.txt remains dead but I found https://github.com/avivgr/teensy_debugdev and http://blogs.msdn.com/b/usbcoreblog/archive/2010/10/25/setting-up-kernel-debugging-with-usb-2-0.aspx Which lead me to google "usb debug cable" and find things such as: http://www.datapro.net/products/usb-3-0-super-speed-a-a-debugging-cable.html and a bunch of ones which don't look right (mostly extension cables or TTL/serial on one end). I have no idea if that datapro thing is actually the right thing, but it looks promising... > Is there another device, which is still available and is known to work? Depending on your platform it might have AMT or some other serial-over-LAN capability?
