** API change: chopstx_poll
This is a kind of clarification. The third argument is now an array
of constant pointers. We don't touch the array itself, just use it.
This allows having the array in read-only memory and can contribute
less use of RAM.
** USB API changes ** USB API changes
INTR_REQ_USB is now defined by usb_lld.h. Enumeration type of INTR_REQ_USB is now defined by usb_lld.h. Enumeration type of
DEVICE_STATE now has USB_DEVICE_STATE_ prefix. DEVICE_STATE now has USB_DEVICE_STATE_ prefix.
