usb serial ch340 driver

Bought a root USB to RS232 serial line, Pl2303 chip. The sellers and the official all said does not support WIN8, but I do not believe in Win7 can use in the win8/8.1 will not be used up.The official latest version of the v1.9.0 driver description said that does not support the win 8/8.1, after the attempt does not support. Hardware can be identified but cannot b
