I have a home-made cable to attach an XBox controller to my PC. Several kernels ago, it stopped working with the following error: device descriptor read/64, error -71.

I don't do much gaming. The kids use it more than I do. I just figured the cable got damaged and I'd fix it when I had time. Today I rebuilt the cable. However, the error didn't go away. I did some Google searching and found a blog post that suggested:

Code:

echo N > /sys/module/usbcore/parameters/old_scheme_first

This worked.

My question is, why did this work? What does old_scheme_first do? Is there some reason this isn't set by default?

Just wondering if anyone has any thoughts on this.

Thanks,

Chris
