Mysteriously, after this had been completed, the Garmin device was able to connect to MapSource again.Īnother piece of info: Occasionally when turning on the connected Garmin device, a BSOD occurs, with the grmusb.sys as the cause of the bugcheck. All protection was re-enabled, and a quick scan was done. Next, I re-opened Norton, and as expected, it informed me that my protection was off, so I clicked the button to automatically fix it. However, even when I disabled all Norton protection, the Garmin could not connect. The same error as I get in the original install. When I installed it on the fresh Windows install, the Garmin device could no longer communicate with MapSource. When the 60CS is working properly, it is with the native Windows USB driver, not the Garmin driver.Īs for the still non-functional USB communication on the "primary" Windows install, I may just leave it alone, and just switch to the "second" boot when I want to use this device.īut I would really like to know what is going on here.Īfter further investigation, it appears that the cause of the problem is Norton Internet Security ver 21.1.0.18. Note that when installing MapSource software, I never allow the installation of the older Garmin USB drivers - I have read the warnings about this causing BSOD, and I have had this experience. I believe this is evidence that something - Windows update, or other software install updated the Windows native USB driver, and doing this it cannot recognize the old USB device (the GPS MAP 60CS). Now the GPS device is able to transfer data to/from the PC. Next, I re-installed Windows 7 Ultimate SP1 X64 in the 2nd boot of the dual-boot system, did not allow any Windows updates - and re-installed the Garmin MapSource City Select 7.0 software. I tried booting into another install of the same OS (I have dual-boot on the system), but it did not work there either - same error messages. I attempted a system restore, thinking that the recent install of another USB device caused the problem, but this had no effect. This GPS device was working properly at one time, and it works properly on another computer, which is running Windows XP SP3, so I know that the GPS is not defective. Whether or not I get this message, when I attempt to transfer data to/from the GPS device from MapSource, it is not automatically detected, and when I click the Find Device button, I get a popup with the message: No devices found.Īll other USB devices are functioning in all USB ports, so I know there is not a hardware problem. Either nothing happens when I first plug in and turn on the GPS device, or, if the 60CS has never been plugged into the particular USB port, I get the popup "Device driver software was not successfully installed" I have tried all USB ports with the same result. The system is Windows 7 Ultimate SP1 X64. My Garmin GPS MAP 60CS will not communicate with Garmin MapSource City Select V7.0 on my system.
