Expecting it to be simpler and potentially faster to send dump commands and simply provide pointer to ram buffer within usbFunctionSetup. Saves about 70Bytes of code, so not huge, but whatevs..
AVR Memory Usage
----------------
Device: atmega164a
Program: 2594 bytes (15.8% Full)
(.text + .data + .bootloader)
Data: 53 bytes (5.2% Full)
(.data + .bss + .noinit)
Base line rom/ram usage.
usb read/write functions are enabled, but long transfers are not.
host support only for LED on/off.
2KB of 16KB (12.5%) of program memory are not available due to bootloader.
