Vusbtiny nenavaze spojeni pres usb (vyřešeno)

Sestavil jsem si vusbtiny isp podle https://harald.ist.org/howto/avr/vusbtiny-isp/ a https://simpleavr.github.io/old_projects/avr_vusbtiny/index.html (a nekolika dalsich autoru, ale jedna se totez zarizeni) s attiny85, nahral do cipu vusbtiny.hex ale pojistky nechal v puvodnim stavu abych mohl opet nahravat. Zkusmo jsem to zapojil do usb v noutasu a z dmesg dostal toto:

[110505.801822] usb 1-1: new full-speed USB device number 23 using xhci_hcd

Je to jen na breadboardu, takze zapojeni muze mit chybicky a ani ten sw postup nejspis neni uplne koser, ale presto - ukazuje ten vypis kde bude asi chyba? Kdyztak predem diky za pripadne tipy.

Vyreseno. Pokud to nekomu pomuze, tak jsem zmenil hodnotu lfuse na E1, prohodil usb vyvody d+ a d- a ted dmesg vypise:

[156768.524308] usb 1-1: new low-speed USB device number 32 using xhci_hcd
[156768.678837] usb 1-1: New USB device found, idVendor=1781, idProduct=0c9f, bcdDevice= 1.04
[156768.678853] usb 1-1: New USB device strings: Mfr=0, Product=2, SerialNumber=0
[156768.678863] usb 1-1: Product: USBtinySPI

Ted muzeme zkouset jestli bude programovat cipy s nezmenenou hfuse (aby se dal firmware vusbtiny i nadale prepisovat).
