Попробовал подключить hashbuster nano к raspberry pi и заметил резкое уменьшение скорости майнинга с 2.6Ghas/s до 300Mhash/s. При чем скорость майнинга на стороннем ASIC (BFL) не уменьшается.
Из-за чего может падать скорость?

Нет, а что затык может быть в этом? На ПК такой проблемы небыло Smiley

p.s./ Не думал, что для 1го nano нужна подпитка от БП. Аналогичная проблема сегодня появилась на ПК через пасивный ХАБ

БОЛТ, проблема в чем-то другом Smiley Включил hashbuster nano через D-Link DUB-H7 и даже через порты Fast Charge скорость резко падает Sad до 300Mhas/s с последующим зависанием hashbuster'a
