Dell Precision USB problems
Hi I have a Dell precision 390 with 7 usb ports (2 front 5 back) running Centos 7 linux os. I plugged in a old graphics tablet to see if it could work, it didn't. But after I unplugged it my keyboard/ mouse (wireless logitech w/usb dongle) quit working. It turns out that only one usb port is working the one at the rear next to the ethernet port.
I have pluged in my cell phone into all the ports but only the one at the rear shows the phone loading in the /var/log/messages file. The others seem to have power as the phone reacts to the connection and shows charging. I booted from a disk into Puppy Linux and got 1800 lines of
unable to enumerate USB device on port 2
All the linux command line tests I ran in Centos 7 ran with no errors and were comparable to my other 390
lsusb
dmesg | grep -i USB
dmesg | less
usb-devices
Showed no error problems.
Is this a software issue or am I looking at a bad motherboard?
Thanks
Jim

Shame on you for double-posting! :BigSmile:
You can try clearing BIOS. I guess you'll have to do this with keyboard connected to the one working USB port:
And for future reference, the Precision Fixed Workstation forum is here.

sorry I did realize that my earlier post had finally showed up. It was not my intention to double post.

precision 390 is ancient windows XP machine from 2002.
CENTOS is not supported here.

why not start simple use only mouse to test all USB ports.
make sure all are turned on in BIOS>
make sure a USB memory stick works on all USB ports.
simple.
SOME PC don't like other PCs to connect to the PC , PC To PC direct, and caused the power wakeup features to go nuts. (or on some PCs weak 100mA ports USB are too weak and do not like your cell phone there or like kind charging, )try simple first OK>?/
or a keyboard as test all ports. 1 by 1.... but a mouse uses less power, way less, so is BETTER TEST.

old PC, year 2006, 13 years old. today./
Centos v7. so did it run centos for years and failed just now or just loaded Centos this week.
like windows 10, Centos 7 is new and like MS windows they drop driver, on VAST chips, infact you can even ask Centos for the list of USB chip drivers dropped from V7 heck even before v7
so why not run 2006 version of CENTOS and pray.Centos , 5 is 2007 release.
Some PC has have 2 chips, USB2 and USB3, and bios not supported USB2 boots.
I have no idea at all what USB chips you have there, Id use HWinfo32.exe or Linux, equiv to see what chips there are. for sure. Lspci command? IIRC,
for sure Linux kernel drop drivers, for sure. (just on age or maker will not support Linux reasons, Reality reasons)

You win the prize. But after installing the battery and rebooting the Sata Operation page was reset to the default "RAID Autodetect / AHCI so I had to change it back to .... RAID Autodetect / ATA also the time of course.
So now its back running and all the usb slots are working.
Thanks for all the responses. After the first on I though I should go back to the cave and work on inventing fire..

@jamby1- Glad that solved the USB problem. :Yes: :Yes:
Given how old this PC is, it probably was built before fire was invented. But don't be playing with fire in caves, just yet. You may have another issue...
If the default SATA Operation setting in BIOS really is RAID Autodetect/AHCI (service manual doesn't say) but you had to change that to RAID Autodetect/ATA to boot up after clearing BIOS, then you don't have Intel's Rapid Storage Technology software and driver installed. That means your HDD isn't taking advantage of the extra speed and capabilities offered by RST.
Did you at some point replace the hard drive and/or do a clean install of Windows (what version of Windows)? RST has to be installed by pressing F6, very early during the OS installation when the prompt appears on the screen about installing "other drivers". It can't be installed after the OS is installed. So you may just want to live with it the way it is...
And please mark this thread "Answered" because your USB issue is fixed...
BTW: What prize did I win?

Errrr. well I don't run windows (except in Virtual Box) I have been running Centos on this box for several years and the last clean install was probably not done as well as could have been. Currently using CentOS Linux release 7.6.1810 (Core). I may have to take a good look at how I install 8 and change those settings.
While I know this machine is old it still preforms the duties I need very well.
The hard drives and OS were replaced several times during the evolution of this computer.
Sorry but the prize is limited to my gratitude.
Thanks again
Jim
