At the beginning , I would like to apologize for my language . I do not know English and I use the Google translator .
My problem is that the internal card reader with USB port does not work as it should . Sam card reader works fine, but when you insert a USB device returns an error 43 in the system ( Device Manager ) . The port is operating properly when very slowly insert the USB device.
There is another problem . Recording to USB while running, but after a while drops to 0 bytes / sec. Built-in USB ports ( connected to the second port on the motherboard ) will also cease to function properly . Copying stops or copying is very slow - a maximum of 1 MB / sec.
What is wrong ?
I tried to update the chipset , but it did not work .
I think the problem is software , not hardware . The reader has already been sent back for warranty because the port is moved , but before sending the USB checked . It worked just like now . They sent me a new reader , and it is the same .
After disconnecting the reader, everything goes back to normal. Built-in function as they should.
System: Windows 8.1 x64
Motherboard : GA- 945P - DS3
Thank you in advance for your help.
