Thanks to all for your help, I have it working, and am very happy to be up
to date in BSD.

For the record, one of my HID had different report IDs AND different report
sizes, so I had to add my hack to send the size for it to work correctly.

The bonus with that is that my touchscreen, which has badly ported HID code
from the original USB firmware, and does not correctly report its report
sizes, can also work with uhid.

Thanks again
