Recently I am utilizing windows 7 operating system but it is for the first time I am using this and I have gotten a big trouble, in this PC is not able to recognize my blood glucose meter. I have contacted the software supplier who suggested a number of drivers and either it donít work or I am not able to install them properly. The whole thing worked very well on my old windows xp pc which died in recent times. I obtain the warning USB Device not Recognized When I begin to investigate in the system the only bug code I am able to discover is that windows has found the driver but disabled the device(Code 43). The software dealer provides me the following information.The Lifescan USB cable has an inbuilt prolific chip, so you are able to make use of prolific drivers as well. And as usually Vista drivers works too along with Windows 7 it should be no difficulty to install a prolific vista driver such these here to connect you meter with your PC: Just to provide more information the lead has a USB on the computer end and a 2.5mm Jack on the computer end. The glucose meter is a life scan one touch ultra. I am an insulin dependent diabetic and at the present I have to go back to how results were recorded 10years ago, Pen and paper. Windows 98 was enhanced; this type of medical stuff for me is much more important than videos or games please help if you are able to.
