Ugh. That looks like a bug in usbhid that I introduced. A fix is not trivial. In short, I did not think the device could be undergoing a queued resumption while suspend() is being called.

I wonder why this is happening. Hmmm ... seems to me that in this case, the problem might be that there is a device hanging in the air, for which the parsing of report descriptor failed (interface .0002), but it's still somehow there on the bus. It's a bit strange that we are not seeing dev_err(&intf->dev, "can't add hid device: %d\n", ret); message from usbhid_probe(), are we? That would mean, that we are returning ENODEV from the usb_driver->probe routine properly. Bruno, could you, for testing purposes, check, whether the patch below changes the behavior you are seeing (and also check what the actual return value from device_add() was, see the added printk()).
