Wheel mouse moves downwards

[Pyrotechnic]

Hello.

I just reformat my lap (HP Compaq nx7300) is the use of a docking station to which I connected a USB wired optical mouse connected to the serial port through a converter, and before formatting functioned perfectly but to me from the Format to start, when turning the wheel upwards the cursor goes down and if the downward shift is also down, if I disconnect and reconnect, the problem is solved, but obviously not something amiss, and I do not think it is normal to do this every day to work. I would appreciate can support me, I did what I could on the control panel but I do not see anything to tell me that I do:

I have the following drivers:

C:\WINDOWS\system32\DRIVERS\I8042prt.sys C: \ WINDOWS \ system32 \ DRIVERS \ I8042prt.sys
C:\WINDOWS\system32\DRIVERS\mouclass.sys C: \ WINDOWS \ system32 \ DRIVERS \ mouclass.sys

1) Open the Device Manager and see if an icon appears next to yellow mouse
2) tried connecting it to another port?
3) Do you have wheel optical mouse?

Not only said Mouse compatible PS / 2, but below the mouse appears a yellow question mark that says: Other devices, device unknown but I do not think that relates to a mouse.

Where is my optical mouse with a wheel, is branded "WISH" and I do not remember that I have delivered a CD to install it.

I will try it in another USB port directly because what was at the Port serious, through a converter.

Probe and I tell you.

Thank you
