I recently got this bare-bones USB-TTL adapter which unsurprisingly contains a knock-off Prolific chip but on top of that it is entirely without the crystal oscillator. It seems to be missing some capacitors labeled C1 and C2 as well (possibly for the unused 3v3 output).

Has anyone come across a USB-TTL adapter based on clones of the PL-2303 (HX/HXA/XA) that needs no crystal? Is this adapter likely to work despite the unpopulated component footprints? Should I be suspicious of elevated risk to any devices I may connect to it?

Has anyone come across a USB-TTL adapter that needs no crystal? Will this work if I try to program with it? Is there any risk if I try to hook it up to my PC and ESP32 module?
