I was running 4.17, but after having used 4.18 (no SPx) on my portable, my AVRDragon was updated.
On my regular machine, AVRStudio 4.17 now complained that it could not run with the new firmware in the AVRDragon, so I thought I'd update to 4.18 on that machine too. Installed SP1 and SP2 also.
But, after having done that, neither my AVRDragon or the JTAGICE MKII work anymore.
AVRStudio cannot detect the USB devices. Same from the command line, cannot detect.
Looking in device manager, they look fine, under the Jungo entry.
All machines are running 64-bit Windows 7, and everything used to work just fine.
Anyone seeing something similar?
