According to the Old Wiki, you could not hook USB 1 devices to the OTG port ... That's why they suggested the hub ... Can somebody from Gumstix confirm this ? Has the spec changed ??

The OTG port is USB2 but can handle USB1 devices without hubs, in USB terms it's a USB2 port capable of working in HS (High Speed, 480Mbps), FS (Full Speed, 12Mbps) and LS (Low Speed, don't remeber the value) mode. The other USB port instead is USB2 HS **only**, so you need an hub to connect USB1 devices.
