ExpressCard USB3 adapters - read speed issue [SOLVED]

[dr_st]

I am currently in the process of investigating yet another ExpressCard adapter, with ASMedia chipset (this, among other things, is what delaying my USB3 review ).

I'll see what conclusions I reach. If only I had a personal X220 to test it on.

[precip9]

I'm using the Renasas based Transcend card,
http://www.amazon.com/Transcend-Express ... xpresscard

on a W500 running W7, and a T400 running W8.

On the W500, the throughput is quite decent, CrystalMark ~90 MB/s, real world ~ 65MB/s

On the T400 with W8, real world ~ 15 MB/s, slower than USB 2.0 on the same machine.

The Renasas card was not originally recognized under W8, but a driver update this year fixed that. Unfortunately, it is so slow under W8, there is no reason to use the card.

The construction of the card is adequate IMHO, though it is practically necessary to plug/unplug the USB cable with the card removed from the machine. A 34mm card in a 54 mm slot is simply not rigid enough otherwise.

dr_st - I signed up for the forum just to THANK YOU for this thread :-).

I have been struggling for some time with an x220 tablet, flush usb 3 express cards and nothing but dodgy, erratic behavior. I had not thought about power saving features at the PCI level because the symptoms didn't line up for me, but after reading this, changing the BIOS to disable power saving on PCI fixed the issue totally. Awesome.

Details in case someone else has this issue:

x220 tablet, Windows 8, both Startech and AKE NECXG USB3 Express cards (I bought another thinking the first was bad, but it looks like they have the same chip set. Turns out they both work fine). External USB 3 disk enclosure with a Crucial SSD, used for VHDs for a small VM lab.

Behavior with default BIOS settings:

Boot, then plug the Express card in - machine becomes sluggish, System process uses more CPU than normal, erratic mouse movement, stuttering sound.

Remove the card, machine works normally.

Put the card back in, but then reboot with it in place - everything works, including the card, external HDD.

Try to eject and then physically unplug the external hard drive from the express card, the card pops out of the laptop ('natch.) Junk, flimsy mechanical connection holding the card in has less grip than the USB plug. Result: same sluggish symptoms, slow mouse movement, stuttering sound.

Reboot, back to normal.

Sleep and then wake (or close and open) the machine with the card in causes the same problem.

Changing the BIOS setting for power saving on PCI seems to have solved the issue totally - I can plug and unplug the card, and the USB driver loads correctly and the machine works now (which is handy given the cards' tendency to pop out!)

Hi onupdatecascade,

Glad this thread could help you.

Unfortunately you may be sacrificing quite a bit battery life with disabling all PCIe power management features.

If you find the battery life drop unacceptable, consider using an automatic script to run something like setpci and turn it off specifically for the ExpressCard root port.

[onupdatecascade]

That might be a bit out of my depth (not a very accomplished hardware/driver guy :-). If the battery really becomes a problem I'll try to figure that out. Thanks again.

dr_st THANK YOU FOR YOUR WORK!
But i haven't this problems at all. I have ASMedia USB3 / ESATA3 combo card (ESATA -> USB Hub -> ASMedia XHCI) AKE branded from China

To examine your findings i have lspcied my T61 frankenpad with Middleton's BIOS... And ALL ASPM is disabled on PCIe root (for ExpressCard) and XHCI. I have rebooted and suspended | restored dozen times with card in notebook and all ok. This evening i'll test speed on my USB3 2.5" HDD. I can try to use SDD in USB3 enclosure to test for more agressive speed tests...

PS
And i want to test setpci to enable powersaving on this controller because i use it not wery often...

[dr_st]

Yes, from all the cards I tested, only the Renesas ones triggered ASPM on the root port. ASMedia/Fresco did not, so your findings are consistent with mine.

Furthermore, I suspect that if you try to enable ASPM (esp. L0s) on your ASMedia card, you will run into issues with it working at all.

[Lockheed]

@dr_st,

Could you give me a hand? I fail to set it properly on my card. The card's PCI ID is: 1912:0015

and so

# setpci -d 1912:0015 50.b=42
# setpci -d 1912:0015 50.b
01

but the change never occurs.

What am I doing wrong?

[dr_st]

You are not supposed to do it on the card, but rather on the PCIe root port that the card sits under.

You can run lspci -t to verify. It will look like this (this is from my desktop, so the details are different):

C:\>lspci
00:01.0 PCI bridge: Intel Corporation 4 Series Chipset PCI Express Root Port (rev 02)

00:1c.5 PCI bridge: Intel Corporation 82801JI (ICH10 Family) PCI Express Root Port 6
03:00.0 USB controller: Renesas Technology Corp. uPD720201 USB 3.0 Host Controller (rev 03)

( I removed all the devices except the root ports and the USB3 controller)

C:\>lspci -t

+-1d.7
+-1e.0-[04]--+-00.0
| +-01.0
| \-03.0
+-1f.0
+-1f.2
\-1f.3

This tells you that the device on Bus:Device.Function 3:0.0 (which is the USB3 controller in my case) sits under device 0:1c.0 (which in my case is PCIe root port 1).

So in my case I would do:

setpci -s 0:1c.0 50.b

And if it comes back as 43 (L0s/L1 Enabled), I would change it:
setpci -s 0:1c.0 50.b=42

If you also which to change the settings on the controller itself, then the offset is not 0x50, but 0xB0 (check the -xxx printout).

So it would be:

setpci -d 1912:0015 b0.b=42

[Lockheed]

Alright, I think I have it working. Thanks.

If you also which to change the settings on the controller itself, then the offset is not 0x50, but 0xB0 (check the -xxx printout).

But why would I want to change the setting on the controller (you mean the USB card itself?) if the only one important is on the Intel bridge?

[dr_st]

But why would I want to change the setting on the controller (you mean the USB card itself?) if the only one important is on the Intel bridge?

I see no reason why you should, at least for the issue described here.

I've seen some other issues with this card (mostly talking about the terrible lag on Sandy Bridge system) where it felt like I really had to change the settings on both ends, otherwise they kept coming back. But I haven't investigated it fully.

[MarkScott]

Thanks a lot for this thread. It confirms that I was right to suspect that the generic USB3 Expresscard I've had in my X220 was the cause of intermittent, severe system, mouse and keyboard slowdowns and freezes under Ubuntu 14.04 64-bit. My fix is that I will simply leave the card out of the slot unless I actually need to use it - I've only one USB3 drive that I use for occasional backups.

If anyone's interested, the card I have is a 54mm one, with two USB3 slots and a power outlet jack between them. lspci provides the following info:

That's interesting information. Previously I encountered such symptoms only on Renesas cards, not ASMedia. But I think the reason was that only Renesas was, for some reason, turning L0s on by default. If I turned it on manually for the ASMedia, strange things did happen. It is possible, I guess, that on Ubuntu, the driver messes with the L-states from time to time, causing the issues you have been experiencing, although without further investigation I cannot pinpoint the issue.

[turbo9000]

This is confirmed to work with a no-name Renesas upd720202 under 64-bit Windows 7 on a T520. Funny enough, before this fix, the adapter wouldn't provide enough juice to spin up an external HD in an unpowered USB enclosure. Post-fix it powers up just fine.

With the T520, the relevant bus is 00:1c.3

Startup command: setpci -s 00:1c.3 50.b=42 (sure enough it was 43 before the command was run)

[artic_squirrel]

I have several question due to a lack of knowledge. I came here in order to enable aspm features so that I can save a few watts, both while plugged in and on battery. I run server2012 on a x201. I learnt that aspm is not enabled on windows with the famous error, from powercfg -energy

Platform Power Management Capabilities:PCI Express Active-State Power Management (ASPM) Disabled
PCI Express Active-State Power Management (ASPM) has been disabled due to a known incompatibility with the hardware in this computer.

the solution is here, but I do not want to install grub, because I do not want to have another bootloader and all, at least not before I try solutions not involving this install.
http://forum.notebookreview.com/threads ... on.606100/

In this thread, you try to disable aspm, but I think I can learn a few things from it, because I have also a AKE card with chipset NEC Renesas uPD720202.
The card was furnished with a cd for the drivers, but windwos 2012 managed to install its own drivers.
this is the list of files on the CD from the vendor
http://abload.de/image.php?img=listefic ... ek3rpc.png
http://abload.de/image.php?img=renesasd ... 03xpyd.png
my first question is : should I install the drivers from the vendor or just use the driver from windows or even newer drivers ?

with the driver from windows, I have the following speed

Are they normal/expected ? Can they be better ?

Next, I want to enable this L1/L0 thing for the express card, to see how much the performance decreases and how much power I save.
How can I do this ? How do I calculate the value to enter to enable/disable the L1/L0 feature?

Next, I want to enable L1/L0 for all pcie devices listed by lspci -nn
it turns out that the devices for which L0/L1 are not enabled are

and

but apparently, the setting is lost after standby, which I use a lot. People say that RWEverything or that egup setup can do this, like here http://forum.notebookreview.com/threads ... st-7759675
but I have no idea what to do.

this is the overview of the config with the expresscard plugged in. It seems that it must be the root which must have l0/L1 disabled or enabled., but mine is already enabled and yet I do not seem to get the lack of speed...

I have run the commands

Code: Select all

setpci -s 0:1c.0 50.b=43
>setpci -d 1912:0015 b0.b=43

to enable L1, but even after a powercfg -energy, I still get this

Platform Power Management Capabilities:PCI Express Active-State Power Management (ASPM) Disabled
PCI Express Active-State Power Management (ASPM) has been disabled due to a known incompatibility with the hardware in this computer.

there is also something odd, because my audio chip has no asmp feature reported
is this normal ?

okay so it is even worse because it does work, but it reinitializes the setting:
I run the command

Code: Select all

setpci -d 1912:0015 b0.b=43

and I loose 0.5 watt ! on battery.
But if I unplug and replug the card, the setting is back at

Code: Select all

00

and I must run again the command to gain battery life...

with the drivers RENESAS-USB3-Host-Driver-30230 from renesas, my usb key has quadrule write speeds
http://abload.de/image.php?img=ss2016-1 ... 2m6s1f.png

the other drives have the same speeds or a bit better

[artic_squirrel]

I updated the firmware from 2020 to 2026, without much difference in speeds.
however, I notice that the device manager do not eject the card when I remove it from the taskbar.
In the device manager, the renesas host control get a yellow mark and stays there, even after the card is physically removed.
the problem is then that the next time the card is plugged in, the card is not recognized and I must plugged it out, then plugged it in to get it seen by windows.
anybody has this issue?

[artic_squirrel]

I put in the path the address of the pciutils, but I get the error, in the prompt

Code: Select all

D:\pgm\pciutils-3.4.0-win64>lspci
pcilib: i386-io-windows: IO library initialization failed. Try running from an elevated command prompt.

lspci: Cannot find any working access method.

and in the event viewer

Code: Select all

The DirectIO driver service failed to start due to the following error: 
The system cannot find the file specified.

okay so the solution is to run as admin

Code: Select all

sc delete driverIO

then to delete any key with driver.sys

I do not know why there is a sudden corruption like this, but deleting the service works.

[dr_st]

You mean

Code: Select all

sc delete DirectIO

The only thing I can guess is that for some reason the service "thinks" that the file should not be where it was created and it "remembers" the wrong path until you delete it.

Hallo

The issue has been root-caused, and there is a solution (or a workaround, if you will).

...

nearly exactly 10 years later I have similar issue with his Express card by Renesas. My system is R61 with modified BIOS (no white list, SATA2 enabled). Thanks a lot for your explanation, but I have one question for your solution: should one apply it ONLY if laptop boots with card inserted, or in any case? I mean, I do not need this card permanently inserted into laptop. So, will it work if I just insert it when needed, after laptop has already booted?

Best regards,
Andrey

Re-reading my first post, it seems the workaround is not needed if the laptop has not been booted with the card inserted.

Hello

Re-reading my first post, it seems the workaround is not needed if the laptop has not been booted with the card inserted.

thanks a lot, you confirm what I understood from your explanation.
