Is it working OK with other systems?
Have you checked if it works under MS Windows with the latest driver?
Maybe it's just a wiring / connection problem.
BTW, is it a USB-to-TTL or a USB-to-RS232 adapter?
(The latter have an additional level converter IC etc.)

Have you checked the chip markings?
Counterfeit PL-2303 chips can often be found at the market,
some even imitate the original branding, as stated on the official site:
