Usb problem

[aaperezd]

Hi friends, im Alberto From Chile,

I have tried to connect my kflop through usb but it does not connect, there is a half-second loop where it tries to connect kflop, my laptop detects it then disconnects and then reconnects it and so it repeats, the current configuration is :
kflop + kanalog + konnect.
perform many tests, among them just connect kflop, put jumper 3 and remove the power of 12 volts, but nothing works, what could it be?

Thanks a lot

Hi Alberto,

How are you applying +5V to KFLOP? What are the +5V power supply specifications? USB power is not sufficient when using Kanalog. Remove Jumper J3.
