A warning: The programmer worked some months ago. Then I installed the latest version v6.60 on new Windows 7 installation, and it said it needed a firmware upgrade. I did flash it, but at the end it said flash failed. When I disconnected and connected the USB device, the yellow LED is blinking. Sometimes it keeps blinking forever, sometimes it stops after some seconds and the device is detected by the operating system. But I can't use it anymore in Windows.
Might be a special setup, because I'm running Windows 7 in an Oracle VM VirtualBox. This is what I see when I try to connect the USB device:
But looks like the firmware was flashed successfully, I can use the programmer on an old Windows XP laptop with no problems. The new firmware might have just problems with the virtual machine, which might be the reason that the flashing process reported that it failed, because it couldn't detect it anymore after flashing (looked like it resetted the device after flashing, because I had to attach it again, which then failed with the error message you can see above). It didn't have problems before I flashed it, so if you have a working installation, don't upgrade to the latest software, if you don't need its features. As always, never touch a running system
I didn't follow the whole thread, is there an open source alternative meanwhile for the programmer? Would be nice if I could use it from my main Linux system.
