template <size_t callback_size = sizeof(std::max_align_t)>class CallbackRequest
Defined at line 386 of file ../../src/devices/usb/lib/usb/include/usb/request-cpp.h
A special Request type which can contain a callback lambda to be executed
upon completion of a USB request. The callback_size parameter represents the
size of the callback, and must be at least sizeof(std::max_align_t) bytes.

void take ()It is NOT safe to call take() on a CallbackRequest.
In order to ensure that each CallbackRequest is only
ever invoked once, we make it an error to call take().
