This is not particularly right, as we'll end up having dangling
input device.

The problem is, that when HIDRAW is not set, hid_hw_start()
returns ENODEV as no subsystem has claimed the device, and probe
routine bails out. Which is not what we want.

Does the testing patch below fix the problems you are seeing?

works good.. rebooted a few times mouse connects. suspended a few times
mouse reconnects.

I'd be glad if you could also double-check that device removal and
re-connecting it works well as well with this patch.

with test I did different techniques,
1) regular suspend(leave device on)
2)suspend then shut off device
3)shut off device then suspend
all of these techniques work properly
Thanks for reporting and testing, I have queued the patch.

cool...
