I have just purchased a Coolgear 'U2IrDA Mini' USB-Infrared Adapter in order to be able to connect my Sony Ericsson Cell phone to my computer and transfer files. As i purchased the dongle from a private buyer it did not come with any drivers, however i went to the manufacturer of the chip (STIR4200) inside the dongle - Sigmatel Electronics, www.sigmatel.com and downloaded the lastest driver, Version 1.32.
I then proceeded as per the instructions on the website, i unzipped the files and ran the setup program which installed files into the C:Windows directory. When this setup program had finished it instructed me to then insert the dongle into the USB port and the operating system should finish the installation.
I then inserted the dongle and windows recognised a 'USB Serial Controller' and asked me to either search for drivers automatically or specify a location. I have tried both ways because apparently windows is supposed to have a version of the driver but this did not work. Windows just keeps saying 'The hardware was not installed because the wizard cannot find the necessary software'. Even though I specify the exact folder and tell it not to look anywhere else it just continually does this and the device unusable without drivers.
I then tried to specify a location of the driver from the files that i downloaded from the sigmatel website but it could not find any information about the drive. I have tried other older versions of the driver but it will not recognise the drivers and it just sits in the device manager with a yellow question mark because it has no drivers installed for it.
I have also tried to install the dongle on another computer running Windows XP Pro and it does the same thing. I then tried to on a computer running Windows 98 and Windows ME using the suitable drivers for each operating system and it also would not install properly
A person who i spoke to who works in a computer shop and also has an USB IR adapter to transfer things to and from their phone said the phone's software must be installed for the dongle to be recognised. I had already done this but i went back and unistalled and did a fresh install of the phone software to make sure there are no problems there.
Can anyone please help me with this problem? I have been searching for some suitable drivers but have been unable to find any and i have had no reply from sigmatel either. I am also running Windows XP Professional with SP2 if that helps at all. Any help is much appreciated, Cheers Benny
