When plugging in any USB 3.0 type peripheral such as flash drive, SATA connector, or gigabit ethernet an ssh terminal connecting over the wifi becomes extremely slow to respond, perhaps a few characters every 20-30 seconds or so. Upon removing the device the ssh terminal speed returns to normal.
I am using the original SD card that came with the system. Linux Kerrnel 4.9.0-xilinx-v2017.3 aarch64 and the files on the flash are dated 3/27/2018.
Here is the dmesg command response after plugging and uplugging the peripherals:
I tried plugging in a USB 3.0 powered hub as well to see if it made any difference. The hub came up ok without causing the unresponsiveness, but the same problem occured when plugging in the devices to the hub.
USB 2.0 devices have all worked without causing any problems. tested wifi, mouse, flash drive.
Since my J6 serial port doesn't seem to be working and I don't have a mini display port cable yet, I can't tell whether it's the whole system bogging down or just the wifi connection as I have only been able to connect over wifi.
Perhaps there's an IRQ conflict with USB 3.0 ?
