Power Profiler Kit II not recognized by my computer after pulling out by accident

[Powwow]

First attempt to use the Power Profiler II on Windows 10 didn't work. I was getting [sdfu] No deviceInfo available for the device, code: Argument. Message: Operation device-info failed, [sdfu] No deviceInfo available for the device. Then I changed the Power Profiler version from latest 4.0.0-beta6 to 3.5.5 That worked great for an hour until I sneezed and pulled the USB Micro cord loose. It was in source meter mode. 5 or 6 power cycles later and the profiler registered again. Before then I was getting this error message each time it tried to connect.

For the third time I've tried to connect the power profiler, I get no error. The profiler flashes the green light but doesn't register as a USB device. It doesn't show in Power Profiler -> Select Device no matter how many times I restart Power Profilier. I've tried both 4.0.0-beta6 and 3.5.5. I've tried two USB 2.0 slots and two USB 3.0 slots. I'm using Windows nRF Connect for Desktop v4.3.0.

Is there anything I can do or is the profiler damaged beyond repair?

Hi Austin,

Are you seeing the same issue using another computer?

A few other things to check:

• Have you tried a different cable?
• Have you double checked that you are using the USB data/power connector of the PPK II?
• What do you see in Device Manager?

Have you inspected the USB data/power connector? Is there any damage to the connector?

Please let me know if you have tried the previous suggestions without any success.

Hi, thanks for replying. Seems my problem was the computer. After I restarted the computer a second time, the PPK II always autodetected and connected successfully. I didn't try a different cable or computer since I was blaming the profiler. I was consistent with USB data/power.

Thank you for the update. Great to hear that the PPK II is working again.
