* This is an abbreviated parser for the HID Report Descriptor. We

*
* - We know there are no LONG tags, all short
* - We know that we have no MAIN Feature and MAIN Output items
* - We know what the IRQ reports are supposed to look like.
*
* The main purpose of this is to use the HID report desc to figure
* out the mins and maxs of the fields in the IRQ reports. The IRQ
* reports for 400/401 change slightly if the max X is bigger than 64K.
