`lspci` will list all PCI (or PCI-e) devices. Chipsets should show up on them.
I got no thorough well defined answer yet though

Rahul2001

@BenN POWERSHELL... Yes we know, we know :)

timotree

@Hennes I just don't know what to look for.

Hennes

With the PCI ID you can look up which device it is (like this post does under win7: superuser.com/questions/657879/…)

DavidPostill

@BenN Someone already did the Powershell answer. Can you improve it? :)

timotree

@Hennes Where do I find the ID?

Hennes

18:08

Most of the time though I simply look in the manual of the motherboard.

djsmiley2k

lshw

Hennes

lspci shows you the ID,

djsmiley2k

lspci -vvv iirc

Hennes

@djsmiley2k Yes, those kinds of commands. Depending on OS and distribution

Hennes

I have not used Linux in 1 or 2 years though, so assume I am not up tp date wioth that

djsmiley2k

wow i don't have lspci on this server

timotree

@djsmiley2k -k gives me kernel modules associated with the PCI devices.

djsmiley2k

ah it's -v or -vv or -vvv then

Hennes

going from memory, -v was more verbose

Including showing names rather than IDs

timotree

18:11

How do I find the ID then? @Hennes

Oh wow. There's clippy in this chatroom. :-)

Hennes

Intel Corporation 5100 Chipset Memory Controller kind of gave it away (I already knew it was an 5100 chipset, so that made it easy for me)

For some reason, my laptop's USB 3.0 ports tend to drop connections during large, high-speed transfers. Is there an explanation for this? This is not specific to the device: it happens with any USB 3.0 device capable of moving more than 100 MB/s.

Is this a USB controller issue or what?

It is a Skylake setup with 100 series chipset. There is no Noth and south bridge

Let me backtrack with some history

Way in the past CPU where box boxes and computers full of chips

in due time the CPU could be put in a single chip (micro processor)

And most of the lectronic condensed into about 3 big chips

allquixotic

Our car is the Impala. We are far from home. We need help. Can you make our tree go?

Hennes

(about 286/386 era)

A few gnerations later we got this down to twi big chips.
One for high speed (NB) one for the rest (SB)

Today we managed to cram a lot of the NB functionality on the CPU die, and the remaining stuff on a single chip.

In your case the Intel-GL82Z170-PCH chipset

in short: Z170

I kinda think this is a USB signal integrity issue. Some devices are better than others but the issue happens independent of port.

...okay, this is a signal integrity issue. A different cable is not giving the same issues.

The new USB 3.0 cables I just bought are doing this constantly.

My laptop seems to be abnormally picky about USB 3.0 signal integrity.

Perhaps some clip-on ferrite beads might help...

My laptop's USB ports have always been abnormally sensitive to interference.

It happens with other USB 3.0 devices.

I'm wondering where my laptop may be coupling noise...

Tried disconnecting other peripherals, didn't help.

I'm going to have to add a ferrite bead.

Any ideas on how to resolve USB 3.0 EMI issues?

Will ferrite beads help?

amazon.com/stardrift-10-Pack-Diameter-Ferrite-Filter/dp/…

@allquixotic, any ideas?

(yes, I measured my cables)

Hennes

I am not an electrician, but they might actually hurt.

There are ferro magnetic. So they act on different in voltage causing difference in magnetic field which .....

allquixotic

@bwDraco I have a bunch of various sized ferrite beads, which I've found to be tremendously useful to cancel out EMI in analog 3.5mm audio cables, but on one occasion actually caused my USB cable to stop working altogether until I removed the bead

Hennes

They should npot blocl DC, but will block a range of AC

bwDraco

Will they interfere with USB 3.0 signals?

Hennes

And at 5GHz signal rate I have no idea is that is mostly ignored or blocked.

allquixotic

19:39

@bwDraco don't know, they might

bwDraco

I want the cable to reject outside noise.

Hennes

It does not differentiate between outside or inside (is that evena thing?) noise

It just damps alternating signals in a certain frequency range.

allquixotic

the data signal produces a strong enough magnetic field in some cables that installing a ferrite bead will affect the magnetic field enough to damage the signal to the point that it's just indecipherable noise to the other end

bwDraco

I guess the problem is my laptop, though cables can exacerbate it.

Hennes

Yes, finally someone else but me who uses exacerbate

Last time I used it I was asked to explian what it meant.

bwDraco

19:42

These aren't exactly low-quality cables.

They're just longer than most (6 ft); this is increasing susceptibility to EMI.

The higher the data rate, the more likely the hub is going to drop the connection.

Michael Frank

are they running alongside other cables?

You might be able to mitigate the interference by just moving the cables.

bwDraco

Doesn't seem to be alien crosstalk, already tried disconnecting other devices.

@djsmiley2k I doubt this is the issue. I've even unplugged my laptop.

bwDraco

19:49

Linux has this message: port X disabled by hub (EMI?), re-enabling...

Michael Frank

So you're plugging a hub into your laptop and the data rate from hub to laptop is poor?

bwDraco

It disconnects at USB 3.0 data rates. The higher the data rate, the more likely it is to disconnect.

It even caused my USB 3.0-capable camera to freeze during transfer, perhaps due to the unexpected response from the laptop (though I normally remove the card and use the media reader)

Not a hub, but pretty much any USB 3.0 device.

Michael Frank

Could be a dodgy hub?

Oh. Internal hub, got it.

timotree

@Hennes So my mobo just has a chipset? (No north or south bridges?)

Hennes

Your chipset consists of one chip.

It weird to call a set of 1 a set, but hey, historical reasons.

bwDraco

19:55

Ungrounded USB ports?

timotree

Okay, so that means the coreboot chart is just out-of-date.

Than you!

s/han/hank/

Hennes

Coreboot had a long way to go when I last head them at FOSDEM (2015 IIRC)

A nice firmware, fast, but still limited to a few chipsets.
And with only a handfull of developers there is not that much they can do to keep up.

Burgi

why are apple chargers so expensive?

Michael Frank

> apple

timotree

Because they have a monopoly on the chargers so they can charge whatever they want to. No competition.

(Also nobody wants to compete for lightning cables when they're inferior to type-c)

bwDraco

20:10

@allquixotic Would a ferrite bead impact the signal being transmitted within the cable?

I thought they just help reject noise going in and out of the cable.

timotree

Is it better to accept a worse answer from someone with less rep to help them climb the ranks or accept a better answer from someone with high rep?

djsmiley2k

a signal is noise

accept the best answer

Michael Frank

@timotree Always accept the best answer.

You can always upvote an answer you like, but don't accept.

djsmiley2k

ferrite beads don't differentiate between signals, other than on frequency

As per wikipedia 'A design that uses a ferrite bead to improve noise filtering must take into account specific circuit characteristics and the frequency range to block. Different ferrite materials have different properties with respect to frequency, and manufacturer's literature helps select the most effective material for the frequency range.'

so, just clipping a bead on may or may not do what you want.

Michael Frank

@bwDraco Did you place the cable straight through the bead, or wrap it around once?

timotree

20:20

@MichaelFrank I just found out you can upvote multiple answers.

That's great. Then I can do both!

bwDraco

I'm not going to wrap it around. One ferrite bead will be placed at each end of the cable (I have not yet ordered).

djsmiley2k

but it might actually be the cables

or the laptop

Hennes

20:45

Start with one bead at the end of a cable.
Test, if it does not improve feel free to try with a second bead.

Michael Frank

@Hennes I would try one bead, once on each end first.

Wrapping aluminum foil around the cable seems to be helping ._.

That just proves it's EMI.

(USB 3.0 cable hooked up to external SSD)

I previously could never get the Anvil's Storage Utilities benchmark to run to completion; the connection would just drop in the middle of a transfer.

Having to shield the cable like this is no fun :\

(SSD in enclosure only supporting up to SATA 3 Gb/s)

Michael Frank

So, new cable time I suppose?

bwDraco

22:58

This is my old, short cable, which would still drop the connection at very high transfer speeds.

The new cables are worse because they are longer and therefore more likely to couple noise onto the line.

I'm getting ferrite beads and will determine whether they address the issue.

My laptop is abnormally sensitive to interference.

AFAIK Sony are the only ones to implement a "Do not connect automatically" flag in Wireless settings
