Problems Installing "G72/VK-172 G-Mouse USB GPS Dongle Glonass Beidou GNSS Receiver Module" (New model of the VK-172). Help and Support Please? I recently purchased on Amazon the "G72 G-Mouse USB GPS Dongle Glonass Beidou GNSS Receiver Module". [CODE] amazon.com/Diymall-G-Mouse-Glonass-Raspberry-Aviation/dp/B00NWEEWW8/ref=psdc_3248676011_t1_B07SMRXSC8 [/CODE] I carefully followed the installation instructions which I downloaded from the ublox.com site. I downloaded and installed "u-blox GNSS Standard Driver for Windows, v1.2.0.8". I checked the windows device manager and the "u-blox GNSS Receiver (COM5)" drivers appear to be properly installed in Windows 10/64. Whenever I insert the "G72 G-Mouse USB GPS Dongle Glonass Beidou GNSS Receiver Module" into the USB port on my PC, the indicator light Flashes once only and then the unit is DEAD. I downloaded and installed u-centersetup_v21.02.exe.zip, and loaded u-center_v21.02 and it actually recognizes "G72 G-Mouse USB GPS Dongle Glonass Beidou GNSS Receiver Module", BUT the unit fails to activate. Please advise what I should do? Is there some installation & configuration procedure that I have missed? OR is the unit "G72 G-Mouse USB GPS Dongle Glonass Beidou GNSS Receiver Module" defective? Thanks in advance! TG
