The big difference I found is the way that they schedule request in periodic schedule introduce by 3ca9aebac2ebb8f56d2d097636b8c568320a9f87 from v3.10 What I will try to do is to go to 3.18 that I know that already was not working. Revert couple of change in usb that make ehci registers register difference and test again This is the controller status after insert the key bus platform, device ci_hdrc.1 EHCI Host Controller EHCI 1.00, rh state running structural params 0x00010011 capability params 0x00000006 status ce088 PPCE Async Periodic Recl FLR command 0010075 (park)=0 ithresh=1 IAAD Async Periodic period=512 RUN intrenable 37 IAA FATAL PCD ERR INT uframe 2f78 port:1 status e1001805 112 STALL POWER sig=j PE CONNECT irq normal 572 err 0 iaa 202 (lost 0) complete 572 unlink 20 In csv you can find capture from 2.6.x and 4.1x kernel.
