We have found a work around, on how to get the BU-353 to work on Windows 8. We have tried these steps on our Windows 8 laptop, and it seemed to work.
Can someone try this and see if it works for you?
1 - Remove the Windows 8 Driver by going to your Device Manager (CTRL + X), go to Ports, right click on the "Prolific USB to Serial.." device and click Uninstall with the delete drivers option.
2 - Reboot.
3 - REMOVE the BU-353. *** Don't plug in back in until step 6 ***
4 - Install the older driver: http://www.usglobalsat.com/store/download/62/windows_allinone_usb_driver_v130.zip
. (May need compatability mode to do that)
5 - Tell windows to NOT automatically update drivers (or it will kill the driver each time.)
6 - Plug in the BU-353
7 - Test with the latest verison of GPSInfo: http://www.usglobalsat.com/store/downloads/GPSInfo.zip
We would love to hear your feedback.
