R520 USB3 not USB3-ing after USB2 (CentOS 6)
The SS (USB3) port on the back has worked fine for years. I mistakenly plugged a USB2 cable in the port to an external USB drive. It was found and worked, but of course, it was slow. Realizing my mistake, I plugged in the proper USB3 cable, but the drive is never found by the OS. Any USB3 device plugged in gets nothing. Rebooting hasn't helped. I was going to next see if somehow USB3 was turned off in the BIOS and/or try a full powerdown, but it's a server and I'd like to avoid it if possible. Anyone ever seen this before? Cheers.

Hello
I'm pretty sure USB 3 was not added to our servers until 13th generation. You can review the system manual on the support page for USB specifications.

Based on the output, it looks like it is detected by the OS as a USB 3.0 port. This is likely a software issue. You can boot to our support live image to see if the issue persists in another OS.

After much ado, it appears to *not* be the operating system.
Here are some things that did not work:
reboot
kernel upgrade + reboot
bios upgrade
But what did work was to completely shut down the machine, disconnect
the power, wait a bit, plug it back in and then bring it back up.
After that, the USB3 port on the R530 recognized USB3 disks again.
Cheers.
