Hi there.
I made a picoAVR and uploaded the pre-compiled firmware in the repository. A WINUSB device with product name picoAVR and a serial device did show up in the device manager. However, when I attempted to detect a chip with avrdude, it complained

avrdude error: cannot find USB device with vid=0x16c0 pid=0x5dc vendor='www.fischl.de' product='USBasp'
avrdude error: unable to open port usb for programmer usbasp

It this problem related to the product name of the programmer? Or special parameter should be added for avrdude?
Thank you!
