Problem with driver - Chinese arduino uno ch340g

Hello
I’m new enthusiast with Arduino , and I make mistake to buy chinese arduino.And now I can’t connect it to the computer.The communication between PC’s USB and arduino board is based on chip CH340G . On windows device manager is marked as unknown device with Hardware IDs: USB\VID_1A86&PID_5503&REV_0254.
When I install driver from here CH341SER.EXE - 南京沁恒微电子股份有限公司 the arduino board continue to be unknown device.

I think The driver in www.wch.cn are for different Hardware IDs and when I install them , the device continue not working and is marked as Unknown device.I tried on different computers but result was the same.

Is there solution for this problem.
sorry for bad english

Where you suborn enough to plug in the Arduino before you downloaded/installer the CH341SER.exe? If so, you have to click "Update Driver Software" in device manager and you're done ;)

I tried this but the problem continue ... May be beacause my chip wch340g is with PID=5503 ,and the driver from (http://www.wch.cn/download/CH341SER_EXE.html) can’t install for the chip. Because inf file not include the “VID_1A86&PID_5503” Is there another way to upload my scetch using simple programmer. My PC has Com port and Lpt port. Thanks in advance.
