I've an Olimexino (Maple R3) and Segger J-Link. I've tried "prodTest_OLIMEXINO_STM32.bin" with Windows 7 (64-bit) on Arduino IDE v1.6.5; it's working fine. Installation is followed by https://github.com/rogerclarkmelbourne/Arduino_STM32/wiki/Maple-drivers
Now I want to try "maple_rev3_boot20.bin" from https://github.com/rogerclarkmelbourne/STM32duino-bootloader/tree/master/STM32F1/binaries
, but it does not work. Win7 os is not detecting the USB port as well.
