I added the usb_detach(); but no difference.

I tried a few things also just as an experiment, such as manually setting register bits:

OTGEN = 0;
DPPULUP = 0;
DMPULUP = 0;
USBEN ...

I should add - my goal is to reach the 0.005 ma (5 uA) draw... but somehow reach that after having run usb_init_cs previously. Essentially I'd like to "un-load" anything that it did. The u ...

I had a look at "bus power only" and had it set up that way, but the biggest issue is calling usb_init... this is what I get:

Test 1
usb_init_cs(), sleep mode, Vbus = 0, Vusb = Vdd (Show ...

Thank you for your response.

I had Vbus pulled down (no USB device connected), and Vusb connected to Vdd. You made me think about that one so I disconnected Vusb temporarily and that brought my cu ...

Hello all,

I'm developing for a PIC24FJ256GB106. My goal is to optimize power draw during sleep mode, which I've done as much as possible by implementing several tricks such as disabling any paras ...
