Hello!
I'm trying to connect three 2.5" HDDs to the ROCK64 computer. To do this, I use an externally-powered USB 3.0 hub. The problem is that I'm receiving errors when trying to access two drives simultaneously.
I've used fio and dd utilities to access hard drives. The example command is "dd if=/dev/sda of=/dev/null bs=128k". When I'm reading from one drives, everything works well. When I'm reading from two drives in parallel, dd and fio utilities hang and ROCK64 disconnects hard drives.
Here are some samples of the errors occured. Each time I'm trying, the new error I receive
Even when I'm keeping only 2 hard drives connected, the error still occurs. But everything works well when I'm plugging an USB hub cable to a USB 2.0 port of the ROCK64. Also, everything works perfectly when I'm connecting the USB hub to my Intel laptop (using the same set of cables and a PSU).
The ROCK64 computer is powered by an official 3A PSU. The USB hub is powered by 2A PSU. Tried several PSUs - no difference. Kernel version is 4.4.77-rockchip-ayufan-136, distro is Debian 9 (stretch).
