I have a USB OTG cable, however FreeBSD is unable to detect when I plug a device in through it. On closer inspection of the schematic it appears the D+ and D- pins are backwards. I've modified a cable to swap these and found FreeBSD can now detect there is a device, although it is unable to talk to it, most likely due to the quality of my soldering.

Am I correct in thinking these pins are backwards on the Clusterboard?

I have a couple of patches for you..
* Speedstepping
* Thermal sensor
* DMA
* SRAM Controller (ETH-PHY)
* PXE fixes (EFI bootloader patch)
* u-boot fixed for a couple of things.
* Almost complete - working devicetree.

I don't use SD, MMC, GPU, I2C, SPI or USB because this cluster is for another project

We currently have 42 sopines so making FreeBSD run perfect is one of my top priorities... haha..  Cool

Awesome Big Grin
