Title: is it possible to put a USB device into suspend mode
Post by: rebar on April 29, 2016, 08:18:25 pm

Is it possible to put a USB device into suspend mode on windows (or Mac)? Curious if any special driver exists to do this.



thx,
robert

This is how it's done in Windows:

thank you for that Jan! - If anyone has an executable that implements this, I'd appreciate it too! (just in case :-)

On a Mac it's a standard function in the IOUSBLib, USBDeviceSuspend. It can be sent from user space code if the code has the device open.
