But this error should occur one time only. I have the feeling that the Labtec Webcam 2200 is not based on the PAC7311 but on PAC7312. The PAC7312 also contains a microphone input and the Labtec Webcam 2200 also have a built-in microphone. See http://www.pixart.com.tw/productsditel.asp?ToPage=1&productclassify_id=12&productclassify2_id=33 for the datasheets.
