If you think about it, it doesn’t matter that the Trinket doesn’t have a built-in USB interface - it does have FTDI serial … and from the perspective of the 328P, it can’t tell the difference if the data arriving on the IO pins the Arduino ISP sketch uses is from that or the 32U4 USB interface chip provided on the UNO et al … You absolutely CAN setup the trinket as a simple and effective ISP! I use it to flash a handful of my other AVR’s (Tiny13, 24, 45, Mega48/88/168’s etc).
I know this has been a few months, so not sure if this will benefit the original posters, but for those stumbling onto this topic via search / google etc.
