Description
Lisa makes available the USB Host (2.0) and USB OTG ports of the Gumstix Overo via picoblade connectors.
USBH
- The usb host connection is standard GND,5V,USB+,USB-
- 2.0 Hi-Speed compliant
Example uses:
USB OTG
- USB On The Go is a spec that allows a controller to behave as a USB Device or a limited version of a USB Host. This is the sort of thing thought useful for digital cameras, for example with a single USB connector on your camera other than getting stuff off of it with your PC, you might load your pictures directly from your camera onto a USB stick or plug in a wifi stick into your camera, or hey maybe a keyboard and mouse? the possibilities are endless (and useless mostly).
- The usb otg connection also has GND,USB+,USB-
- There is also an ID pin
- There is no useful supply voltage.
USB OTG as Host
To use the USB OTG port as a USB Host, the ID pin must be connected to GND and 5V needs to be wired from somewhere. Here's an example wire harness that uses GND and 5V from Lisa's POWER connector:
The default omap3-lisa-image doesn't require any configuration or changes for this to work.
If your device doesn't work try:
- a hub
- a powered hub
- having the usb device installed prior to power on and boot up
USB OTG as Device
Lisa could be used as a mass storage device or perhaps an network device. So far hasn't been tried.

Random Testing Notes
need cleanup
OTH with Hub
edimax wifi - functional, netperf shows 13Mbps throughput to a PC also on wifi mass storage stick - works , read: 68Mbps write: 6.6Mbps
OTG direct
edimax wifi - non-functional rt3070 driver doesn't create an ra0 apparently it's because there's not enough power:
usb 1-1: new high speed USB device using musb_hdrc and address 2 usb 1-1: default language 0x0409 usb 1-1: udev 2, busnum 1, minor = 1 usb 1-1: New USB device found, idVendor=7392, idProduct=7711 usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 usb 1-1: Product: 802.11 n WLAN usb 1-1: Manufacturer: Ralink usb 1-1: SerialNumber: 1.0 usb 1-1: usb_probe_device usb 1-1: rejected 1 configuration due to insufficient available bus power
mass storage stick - works , read: 66Mbps write: 6.8Mbps
Host
- edimax wifi - functional, netperf shows 11Mbps throughput to a PC also on wifi
- mass storage stick FireFly - works , read: 130Mbps write: 6.8Mbps
- HTC Desire phone, Android 2.1, orange network (shows up as usb0, "dhclient usb0" gets it set up)
- netperf through phone to local wifi network shows 7*10^6bps tcp_stream throughput
