Hi Folks,
CentOS 5.5 x86_64
Asrock-Board with 2 USB3 plugs.
Normally USB3-drive is detected. But occasionaly after "umount" next time this drive or other ones will not be detected. I have to boot the PC - than it works - till next unrecognition.
On USB2 plugs all works correct.
No messages in /var/log/messages nor dmesg.
What happens here? Board failure - or other reasons?
Some hints welcome.

Try this: Make (eg) /usr/bin/usb3mount (your own wrapper for /bin/mount for usb3 devices) Include the line for num in 0 1 2 3 4 5 ; do echo "- - -" > /sys/class/scsi_host/host$num/scan; done
Caveat: The number set 0-5 has to do with *my* scsi busses and devices thereon. Your numbers may be different. I use this re-scan to detect hot-swapped sata disks for multi-spindle backup

Maybe I don't really know what effect is expected. I'm not a linux-professionell

"file or directory not found" Look for /sys /sys/class /sys/class/scsi_host /sys/class/scsi_host/host1 ... /sys/class/scsi_host/host8 And see which aren't there.

Hmmm, I didn't think USB3 was even supported in CentOS 5. What does: dmesg|grep xhci tell you? Perhaps it's running in ehci USB2.0 mode.... and maybe that doesn't work too well?
USB3 is supposed to be fully supported in EL6, but following the SL lists shows that that seems to be somewhat problematic with the current kernel and some hardware.

USB3 is supposed to be fully supported in EL6,
So I have to wait until CentOS 6 is tested (testing machine has no USB3) and then is installed on production server.
Not such a big problem cause USB2 works with that drives - but slow ;-(
Thx Timothy

Yeah, no xhci kernel module....

Once you've tasted the speed of USB3 you really don't want to go back..... It's as fast as native eSATA on most of my USB3-capable externals. Over twice as fast as USB2 on them.
An alternative would be to use the ELrepo 'mainline' kernel, assuming it has the xhci and/or xhci_hcd modules; but you'd be on your own configuring udev and friends to use it. If that were to work, I sure would be interested.

No option - too complicated for my knowledge.

This is yet another plea for Centos users with repo knowledge putting the kernel sources where anybody can yum install them, And users with kernel knowledge building a broader-capability kernel (i586, non-PAE, and USB3 are the needed add-ins named on this list so far), And a user to merge our supplied changes into this centosplus kernel.

Which Asrock pcb ?
My desktop is Centos 5.6 with Asrock N68C-S UCC. I format USB memory sticks as ext3.
SD cards (FAT format) are instantly recognised (via USB). However USB memory sticks (4 GB, 8 GB) are recognised very slowly. There appears to be some polling, a flash of activity on HDD 1, a flicker of LED light on the memory stick, some more HDD activity, more memory stick LED flashes then the memory stick is recognised. The process seems very slow and take about a minute or more.

Formated ext. UBS-HDD (500 GB) ext3 / ext2 - both did not work

If it is detected (first time) - that happens very fast. But then ( second time or more) - no detection.

Most of solutions concern WINDOWS. But I will try to find a BIOS-Update. Perhaps this will solve my proplem. Or I will update to CentOS 6.
