I think that is definitely a solution. It does centralize the testing for this particular issue. The only thing question I have is if its really better to have the upper level do the check. Shouldn't the driver itself handle the hardware and device node status? On Thu, 2010-01-07 at 15:07 -0800

n. Since I should consider this unsupported, is there a better driver out there as my company is already well down the road with our design? Or would you recommend just creating our own driver for the USB-OTG? I'm developing with the Kilauea, and I guess I should ask how unstable is Linux sup
