Thread: Windows cannot detect internal and SD memory for Zumo 390LM

Hello
I performed the formatting using the software you indicated following all the software settings to correct format Zumo. I loaded a cure version and Zumo recognizes USB drives. I installed the original firmware version in a previous version and also in the latest one and Zumo no longer shows the USB drivers from both internal and external memory. I loaded a new file package from backup and it still doesn't show SD drivers from internal and external memory. After formatting the Zumo I loaded the original GCD and without any files in the directories, Zumo works but it doesn't show the SD of the internal and external memory. The only option to show the internal and external memory drivers is with the cure firmware. Any other hint?
