Hi Alan,
Now after a suspend/resume cycle, I see the devices
with lsusb, but they are not working (I tried a
mouse), and I get in logs a lot of:
Jan 6 20:04:14 r50p kernel:
drivers/usb/input/hid-core.c: input irq status -84

Now, even a rmmod/insmod after resume does not help
any more.
Tested with both ehci and uhci loaded when suspending.
Thanks,
Paul
