Does not work with Bascom or Atmel Studio.
On Windows XP , same hardware, its works. There I only installed the driver provided by Olimex. Seems to be only Libusb. On XP it is old version of libusb.
On W7 he installs the newer version (I found on internet that this is necessary indeed). But it doesn't work: Timeout.
This timeout-message comes from 'STK500v2' in W7.
When I force timeout in XP (unplug USB) the timeout comes from usblib I guess. See screenshot.
Don't find file STK500xx in driver map, nor in Bascom-map.
try a time out of 100 ms.
also , try another USB port.
you can also try to update the firmware of the mkII. I tested on Win7 without problems. There are however 2 different versions for the mkII : one for use with avr studio, and one for use with libusb (bascom, avrdude) _________________ Mark

I did a firmwareupdate of the MKII. The problem is solved. My previous project was in XP. For W7 and the new libusb you need more recent firmware.
Case closed. Thanks for your suggestion.
