Hi, It seems like my overo earth board does not like usb full-speed devices. Is my observation is correct? It seems strange to me that it does not support USB full speed devices, as they are so common. Is there some work-around? Will it ever change? |

buy a 4 port powered USB hub from your local computer shop. This will support low and full speed devices On 28/11/2010, at 5:55 AM, Yoav Luft wrote: > Hi, > It seems like my overo earth board does not like usb full-speed > devices.

I am guessing since i dont work for the company that they couldn't find a usb transceiver that supported low speed and full speed in the package they wanted. So we have a high speed USB port. The OTG port is separate. Plugging a powered USB hub into the high speed port works. I do think that they havent provided enough capacitance on the 5V line. TI recommends at least 100uF on each usb port for their USB hub chips.

The USB OTG port supports Low-Speed/Full-Speed/High-Speed at 100mA. USB host is High-Speed only up to 500mA. A hub (on-board or external) will allow you to connect Low-Speed or Full-Speed devices to the host port.

Is it possible to directly solder a USB device to the USB host without removing the existing host ports on either the Tobi or Summit board? I can't tell how this would be possible from the schematics, but want to avoid having to remove the existing port in case I damage the board.

Do you know if the problem is hardware or software related? If it's simply not supported by the driver (but could be supported by the underlying hardware) I might venture into patching the driver.
