Trinket USB not working- Can I program ATtiny directly?

Post by Detector73 »

I am trying to use regular adafruit trinket because there is existing code to run the Si5351 board.
I cannot get any USB connection to it in windows 10. No sound, nothing in device driver USB, nothing in Arduino ports. I installed the windows driver from adafruit web, but it did not improve anything ( it did not ask about no signature.)
Tried 2 different trinkets, etc.
Anyway, if I can't use the bootloader - can I make the same program work by programming ATtiny85 directly?
I have programmed ATtiny successfully before. Maybe just kill the bootloader? does this mess up any addressing?

What do you get for lights on the trinket and have you checked the cable for communication ability?

Yes, green light is on and red light flashes on for maybe 5 seconds after reset.
Actually, with a different cable I get the ding and device manager shows attiny under libusb-win 32 devices.
But still no port in Arduino and I can’t upload blink program as a test.
