We get exactly these error codes as well but in a slightly different use
case.
Whenever we make a soft reboot with an "unloaded" B200/B200mini (i.e.
the fpga image was never loaded) we get these error code and the board
is not accessible.
If the fpga image was loaded, soft reboot works.
A power cycle always work.
We have had exactly this issue with all tested motherboard that includes
DFI, Supermicro, Asus and probably some more...
We have not got passed this issue unfortunately.

Hi, we have a Dell server running Centos 7.4 with a B210 plugged into a USB 3
port on the back. Everything works great when we plug in the B210 after boot,
but if the B210 is plugged in before boot the device is not recognized and we
get these errors in dmesg:
Usb 3-8: device descriptor read/64, error -110
Usb 3-8: device not accepting address 6, error -62
We have tried adding external power to the B210 on bootup but it does not fix
the issue. However, adding a USB 3 pcie card and booting while plugged into
that works fine. We have tried this on multiple of the same server with
multiple B210s, so it is not a single device issue. I know there is a reset
button on the board, but we need to be able to remotely power cycle the whole
system. We are in communication with Dell right now, but I wanted to see if
anyone has hit similar issues and how they got past it. My feeling is that
this might be a BIOS issue.
Thanks in advance for any help.
