Re: [beagleboard] Re: PocketBeagle USB1 Question

I have had it running almost like this (but with just a wire in place of the USB power switch module) for a few hours each day for the last couple weeks or so, and haven't let the magic blue smoke out of my device yet! I plugged a wi-fi dongle into the added USB jack, and the dongle gets pretty hot

Graham -- I figured that's probably what USB1_EN is for. Most of the USB power switches have an enable pin (the 4- or 5-legged ICs), but a couple of them don't (the 3-legged ICs). Thanks again for the advice! -- Will On Friday, November 17, 2017 at 12:18:27 PM UTC-7, Graham wrote: > > If your

If your USB power switch requires an On/Off enable control input, that is what pin P1-03 is for. --- Graham On Friday, November 17, 2017 at 12:11:59 PM UTC-6, wi...@geomonkey.com wrote: > > Graham -- > > Thanks for the advice! That totally makes sense. I now intend to try this > configuration

Graham -- Thanks for the advice! That totally makes sense. I now intend to try this configuration to get the added USB1 working in host mode (e.g., to control a Sony camera using the gphoto2 library):

[beagleboard] Re: PocketBeagle USB1 Question

Your first connection does not work, because you are trying to power the USB1 from the USB_VIN, but since the is no power going into USB_VIN on USB-0, there is no power to come out USB-1. This only works when the board is powered from USB-0 The schematic does not tell you, but USB_VIN, USB0_VIN a

[beagleboard] Re: PocketBeagle USB1 Question

I, too, am wondering about the best way to provide power to the board and to a device connected to USB1 as host. Here is how I learned to hook up a micro-b breakout to USB1 and also how I intend to provide power to the board. The problem is that there is no measured voltage at USB1:

[beagleboard] Re: PocketBeagle USB1 Question

Further research, looking at the Eagle board and schematic files for the PB, it appears that USB0.VIN and USB1.VIN are both directly connected to VIN.USB Which explains why I had no power on my USB1 host port when connected like the Fritzing diagram, since I am powering from VIN currently. So t
