Usbmon log is attached. Hmmm. There's one more test I'd like you to try. Move that new msleep() line into remote_wakeup(), just before the line that says: usb_mark_last_busy(udev); Use 50 ms for the delay. I don't expect this to change the behavior, but I would like to see the resulting usbmon log. This is looking more and more like a hardware or firmware problem, either in the device or in your EHCI controller. Ultimately there may be no choice but to disable remote wakeup.
