Finally found the typo that stymied me for the last two weeks heck yeahhhh
i wasn't sure if this probe would work, because it's only rated for 24Mhz and USB FS runs at 12MHz. 2x sampling rate is really the bare minimum, to be safe you want more like 10x. But this looks like a perfectly valid packet. Which is good, because this logic analyzer cost me $20 and a 100+Mhz one costs more like $150
