I just purchased a Leonardo and I'm having issues with it on 7. I plug it in and for about ten seconds it recognizes the device as an Arduino Leonardo under "Other divices". Then it switches to an unknown device under usb controllers. I rush to check the hardware ids before it changes and get USB\VID_2341&PID_0036&REV_0001 USB\VID_2341&PID_0036 Under unknown device it has no information whatsoever.
When I try updating the drivers windows tells me it already has the best drivers for it. I've tried the 1.0 and 1.01 ide's drivers and none work. Could it be a bootloader issue? I also have a duemilanove that works fine.
Thanks in advance, Strix
