I'm trying to figure out where the bottle neck in terms of bandwidth would be.
- no other processes running on raspberry pi (700MHz processor, no overclocking)
- no limit on internet up/down rates no limit on power of external USB hub (5V, 12A power supply)
What is the maximum data rate that the usb bus can handle? What is the maximum data rate a block erupter could ever need (I don't know how to convert Hashes/s to Bytes/s on the USB bus)
Are there tools I can use to grab these numbers (e.g. some utility like netcat?)
Can I put a 10-port usb hub in each of the two raspberry pi usb ports?
