I am just reporting what "speedtest-cli" says. I note that watching "htop" at the same time, on the USB-2 to Ethernet tests, the CPU is maxing out at 100 percent, so the speed is not necessarily constrained by the network interface, but the CPU's ability to feed it, through the USB stack. I

I hacked a "quick and dirty" second USB port as described. Then connected a LAN7500 USB-2 to Gb-Ethernet board. Came right up, drivers are already in the kernel, no device tree changes. Connected to the network at 1 Gb. speedtest-cli results (on a 1 Gb up/down network) Download 27 Mbps, Upload 41

U4 is a USBLC6-2. As for the I2C pullups, I forgot to add to this board as I have them on another. I'll add here too... On Wednesday, October 11, 2017 at 11:42:43 PM UTC-4, Graham wrote: > > Dan: > > What is the part number for your U4 ? > > You are going to have to add some I2C pull-up

Dan: What is the part number for your U4 ? You are going to have to add some I2C pull-up resistors somewhere. Thanks, --- Graham == On Wednesday, October 11, 2017 at 10:08:10 AM UTC-5, Dan Brown wrote: > > If you are just trying to hook up a quick and dirty connection, then tie > 15 and 13

If you are just trying to hook up a quick and dirty connection, then tie 15 and 13 together for grounding the ID pin. Then you will tie 5 and 7 together so the CPU understands there is a USB port in use and it is powered. Your USB connector connects then to pins 7, 9, 11, and 15. Pin 15 is

On the pinouts 5,7,9,11,13 and 15 are shown as USB1. So: tie ID to Gnd (15,13) and 15 to gnd on the connector There is a Vin(7) and Vbus(5). One of those are not used for the +5 connection? So +5 goes to pin Vout(13) Is Vin used when the power is flowing into the PB from the USB? Thanks

On the expansion connectors, the +5V from the built-in USB port is connected to the pins labeled VOUT on the back. GND labels ground pins. On Saturday, October 7, 2017 at 3:05:43 PM UTC-4, Andy Bushnell wrote: > > Which pins are to +5 and gnd? > > Thanks! > Andy > >> >>> -- For more

Issue was solved via help from the IRC channel. Issue was the Extra pins needing to be shorted to GND and 5V. I have now created a Expansion board that adds a Host port with proper switching of power, and ESD protection. Details are at: https://oshpark.com/shared_projects/IrizTrr1 On Friday,
