Hi,
I have J-Link Ultra+ v4.3, bought at Farnell/element14. During debugging the firmware update window appears and I confirmed update. When window disappeared, debugger stopped working and the middle LED started flashed with three short blinks and long period. When I disconnected and reconnected the USB cable to another USB port (because I thought that may be USB or drivers problem), the computed didn't see USB device and the LED blinked red again. After about 2 minutes of blinking, LED turned red. Few seconds later it turned green but still was no visible on the USB devices list in Device Manager. Also, the J-Link Commander/Configurer didn't see the debugger (when the LED was blinking red) or hanged on "Retrieving information for 1. emulator on USB" (when the LED turned green). When LED was green and I disconnected USB cable the Commander printed out warning "Out of sync , resynchronizing...". I also noticed (after I opened top cover to see is there any physical damage) that FPGA is quite hot.
