Hi everyone,
I've recently completed my y1/y2 build. As was to be expected, it doesn't work right now. When I stick the two boards together and plug it in (either USB or the 5V jack), the switch lights up. However, if I plug it into a USB port, the PC doesn't recognize it (it recognized it correctly once, but wouldn't play any music, then it stopped working, after that (I cleaned the boards and reflowed all the joints in between) it said "device malfunctioned" twice and now it's back to not working at all). I want to do the "initial check" tests from AMB's site, but I'm a bit confused if it's possible to do it for the y1 without connecting the USB and DAC boards, since I've already installed the receptacles and pin headers in those places. I checked some voltages without doing that once, and I got like 4.8V on the 3.3V test point and also something wrong on the 4.5V test point (I forgot, I'll test it again later). What's some stuff I should check?
Also, here's some pictures of both boards on both sides:

PS: I tried making this same post on AMB's forums, but somehow it didn't appear in the forum I made it... Maybe it's still gonna appear, otherwise I'll try again there.
