I replaced my development machine with 6 cores, 32 GB etc.
I thought it would be simply inserting the existing HDDs and changing /etc/sysconfig/ifcfg-eth0 but,
* in the UEFI “BIOS” USB2 and USB3 work.
* in C5.11 USB2 works but USB3 does not.
* in C6.5 (my install disk; OS be updated to C6.8) USB2 works but USB3
On both C5 and C6 lsusb shows an entry for the plugged-in keyboard (USB2
socket) and for the wireless mouse (USB2 socket) but nothing else.
Please does anyone have any ideas how to solve this baffling time-consuming problem ?
Is is a UEFI (motherboard Asrock 970A-G/3.1) configuration matter or potentially the absence of a suitable USB3 driver for CentOS ?
