Thanks, I'll give it a try. I hope is not some kind of time based
condition.

By the way, I only see the error when the tablet is connected. If I run
"usbhid-dump" or unload and load the driver, it works as expected.
I don't know if this could be related to the driver failing to process
the response to the magic data... Investigating.
