Thanks for the answer, @attila Seems like that was the problem. I supplied the DVCC1V8 rail from AVCC1V8 like you said and the device seems to be fully functional now. Once again, I really appreciate the help.

I encountered this problem while trying to connect the device: I've inspected the board and can't seem to find any obvious sign of damage. I tried bypassing the IC20 by wiring the VCC5V0 to AVCC5V0, but that still did not solve the problem. I bought this secondhand so it's probably not possible to send it back for warranty. Any help would be appreciated.
