I have been running my DP35DP for some time now with no errors and no problems what-so-ever with WOndopws 7 64 bit. Recently when I went into Devices And Prinetrs, theer was an Unknown Device listed in the Unspecified section. Investigation revealed that it was a Standard USB Host Controller at Port_#0001.Hub_#0002. The status was reported as Windows has stopped this device because it has reported problems. (Code 43). I have not made any recent chanegs at all to my system so I have no clue as to what the proximate casue was. As far as I know, I have all the latest drivers installed. Can someone offer advice as to hwo to rectify this situation please?
