USB suspend current measurement
« on: June 26, 2014, 12:06:29 pm »
Hello,

Is there an easy way to manually put a USB Mass Storage device into suspend mode in order to measure the current drawn by it?

Thank you in advance.

Use the pwrtest utility to put the system in S1 or S3.

For some reason, it's not in the 8.1 WDK, but it's in 8.0:
