| May 8, 2015 at 22:31 | comment | added | Ronny Nilsson | Yes, it's the same (logical) USB port. There is a switch in the board to mux the two physical connectors. If you want to know the details it can be seen in the HW schematic available at raspberrypi.org | |
| May 8, 2015 at 20:10 | comment | added | jhfrontz | On the compute module IO board there are two physical USB connectors (in the pic at raspberrypi.org/wp-content/uploads/2014/06/…, one a host at center bottom and one a device "slave" at bottom left). Are you saying that they are the same USB port? | |
| May 7, 2015 at 21:07 | comment | added | Ronny Nilsson | There is a single USB port only. | |
| May 7, 2015 at 20:28 | comment | added | jhfrontz | Something I read made me think that only one of the ports was OTG and that the other was a pure device port-- I guess maybe that's the question: does the Broadcom SoC on the RPi CM have a single USB bus or are there two? | |
| May 7, 2015 at 16:18 | comment | added | Ronny Nilsson | To my knowledge it's architectural. OTG controllers act either as host OR device. You haven't said what you wan't to achieve, but if it's to connect RPi to a PC I can recommend a USB Null modem cable: ftdichip.com/Products/Cables/USBtoUSB.htm Works for host-to-host connections. | |
| May 7, 2015 at 12:43 | comment | added | jhfrontz | Right, but is that because of an architectural limitation or because an appropriate driver/configuration isn't in place? | |
