Dear Mr. Matt, I mistook your 405 patch on 8xx for test.Actually,there is a perfect solution for RPXlite USB in HOST mode problem on Brad Parker's webpage. http://www.heeltoe.com/software/usb/usb.html
Egg on face! I should be blamed to disturb you all. I list the README of m8xxhci driver 1.4 as follows for clarification.After removing R74/R75(1.5K) as two 20Ks(I only have 20K at hand) to ground on LITE_DW,USB keyboard worked fine.
