Hey, I have a big problem here and I don't know what I did wrong.
I've uploaded VUSB firmware to my controller (ATtiny45)
Change the settings, etc.
When I plug it in, it says Found New Hardware Easylogger
and then it says Found New Hardware Human Interface Devices
and THEN it says Found New Hardware and says that there's a problem......
I mean..what causes this? Enumeration works, device recognized...
whatever can cause the error?
FYI I use the same VID/PID as there is in the HID_data example in:
vusb -> examples -> hid_data -> firmware
I just changed the usbconfig and then uploaded it.
Is there anyone out there that can help me?

You MUST NOT use the same VID/PID pair for two devices with different low level drivers. Windows caches the association of VID/PID and driver FOREVER. Simply use a new pair (see USB-IDs-for-free.txt in the latest driver).

but I did a regedit and erased all the registry that point to the VID/PID

You can also remove the association somewhere in the device manager. I'd recommend separate experimental PIDs, though, unless you really know where to remove the driver association.
