Picoscope 3404D invisible as USB device

Post by Eva Astorsdotter »

A totally new, out-of-the-box, 3404D unit is totally invisible as USB device.
On 2 Windows 7 PC-s, one PC with USB3 port, one with USB2 port, it does not even turn up as general incognito USB device.
Newest Picoscope SW, new unit , first start-up.
Separate 5V power supply.
On connecting AND disconnecting to USB3 port there is the following error message
Power surge on HUB Port
USB Composite device has exceeded the power limits of its hub port.
For assistance click this message.

Clicking the message does (surprise, we are talking Windows) give the same info, only in the device handler.
Do you have any suggestions as to reason and remedy?
Slightly disappointed...
Best regards

Please check the cable , if possible try another USB3 cable or even a USB2 cable.

OK, point taken :) , cable switched and now I have a device and can connect to it.
The emphasis in all documentation was so heavy on using your own special extra super-cable "the Blue one", that I passed over the first, obvious solution.
Need USB3 cable, though, for the tests I am doing.
