[gentoo-user] external SSD problem

[gentoo-user] external SSD problem

[Grant]

I just got one of these:

http://www.newegg.com/Product/Product.aspx?Item=N82E16820208913

It seems to work fine except that once I eject it in Thunar, I get
this in dmesg:

sd 8:0:0:0: [sdb] Synchronizing SCSI cache
sd 8:0:0:0: Device offlined - not ready after error recovery

The only way to get the /dev/sdb device back is to 'modprobe -r
xhci_hcd && modprobe xhci_hcd'.  I've tried two different USB3 cables.
 I have an external USB3 hard drive that works fine but /dev/sdb
doesn't appear after ejecting the SSD unless I modprobe xhci_hcd.
Should I file a kernel bug?

You can maybe also post it to the linux-usb mailing list
(linux-usb@vger.kernel.org), I think there is at least one person
there who works exclusively on XHCI stuff in the kernel.

You might also want to check if there are any firmware updates for the
USB3 chipset on your motherboard. lspci should reveal the chipset. My
old motherboard had a flaky USB3 chipset (Renesas/NEC) that could only
be updated from Windows, so I never bothered with updating it, but
there are some that are updatable from within linux or from a DOS boot
disk.

Thanks Paul.  I'm posting this to linux-usb.  My laptop is a Dell

A bit different topic but similar: I get problems with using a PL2303
usb-to-serial-adapter lately. Same issue on thinkpad and main desktop pc
so that might not be the chipset.

Something like this:

http://www.geekdevs.com/2010/04/solved-unable-to-enumerate-usb-device-disabling-ehci_hcd/

disabling ehci_hcd disabled my keyboard as well so that is no solution ;-)

Maybe I didn't fully understand how to do that ... anyone in here
already solved that?

I use that pl2303 to access embedded PCs like ALIX or WRAP to configure
routers/firewalls ... it would be great to have that available on my
thinkpad again.

Hello Grant,

I've had similar device issues with hardware attached
to the pci bus. I found this obscure command that
updates the master list of pci device "id" on a gentoo system:

/usr/sbin/update-pciids 

This may help:
http://www.gossamer-threads.com/lists/gentoo/user/198486

Maybe there is such a script for usb buss related numbers,
or the ones posted for your devices need updating?

It's a shot in the dark, but may give you and idea
on what's misaligned with that particular device?

hth,
James

to get an idea of the numberings for various

lsusb shows the following for my SSD:

Bus 004 Device 002: ID 174c:07d1 ASMedia Technology Inc.

I updated to hwids-99999999 but 174c:07d1 doesn't match any device in
/usr/share/misc/usb.ids that I can see.  Could that be the problem?

I also noticed these messages in dmesg after removing and reloading
the xhci_hcd module:

Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK
...
Parent hub missing LPM exit latency info.  Power management will be impacted.

Hard to say. These sort of things are difficult to flush out.
You do need to find a dev in this area and make inqueries,
and just keep googling..... and digging. Look for a firmware
dev that works for the company, or open up a trouble ticket
with the company that manufactures the device (if you can find
them).

This stuff is complicated hooking up SD(hard drives) 
that are connected via the usb(3) buss. I use to have
some usb buss analyzer software, but it was MS based
and I do not have access to such fancy commercial software
at this time.

It looks like you've found the error trail. How to fix it,
from my experience, is all about using googl until you find
somebody with the right knowledge.  I'd suggest going to the 
dev (kernel docs) for that part of the kernel for these things to find
somebody qualified to really help you. Somebody to advise
you who really knows what's going on.  Read the comments
for the various parts of the kernel and track down the maintainers
or devs.....


Sorry I could not be of more help.
Good Hunting!

Maybe there is a free usb software based buss analyzer
out there?

Grant.

Does it come back after unplugging and reconnecting it?
When you eject a device. The device needs to send a insertion notice for it to be rescanned.

Eject was originally designed for removable media in a drive (floppy/cd/dvd/...).

Usb stick and harddrives don't always send the newdiskinserted reply to an eject action.
There are some that do. I have examples of both at home.

Knowing you want to use Thunar, and arriving late in this thread, you may
happily press D if this has been discussed...

What happens if you issue "umount /mountpoint" from a vt, rather than clicking
"eject" in Thunar?

Also, hard drives attached via USB give fuzzy results at best. After years of
trying many different things/software in Gentoo, now I just hang a serial
cable out of my workstation, and an external power adapter close. STILL there
are times when it's not behaving properly.

It does not unless I also issue 'modprobe -r xhci_hcd && modprobe
xhci_hcd'.  Another USB3 HD I have comes back after ejecting,
unplugging, and reconnecting, but not the USB3 SSD.

That does work fine as does right-click + Unmount from within Thunar.
Ejecting from within Thunar seems to be the troublesome one.

It appears the problem is with Thunar's "eject" command then. IIRC the eject
apps were more, if not especially, intended for CD-ROM devices. At any rate
you need to investigate what is being run when this script is executed when
you press the radio button (or whatever) in Thunar for "eject".

sys-apps/util-linux obsoleted sys-apps/eject on 06 Sep 2012, and we still
sys-block/eject in portage. Which one does Thunar call?

Sorry I've no time for investigating, and don't have Thunar installed on any
PC atm.
