USB c hub with pd passthrough power will it work? - Google Pixel XL Questions & Answers

I would like to be able to plug a USB cable into my pixel xl on my car and be able to charge the phone and play music.
My idea was to use a USB c hub with pd passthrough power. Plug in a DAC to the hub and a USB c charging cable to a cigarette USB c fast charger.
There are lots available for the Macbooks but will they work with the pixel? Does the pixel allow other devices whilst receiving power?

Hey mate did you find anything like this? I'm after something similar for my 6p to use in my car

It sounds like you need a kernel capable of 'USB OTG plus Charge'. I have only seen this on Nexus devices. Look in your favorite kernel's forum thread and see if there is support.
Pretty sure this is feasible, though I'm not sure if Android 7 has anything that could pose a restriction.

What is the Pixel C USB data transfer speed?

Hi,
I was hoping someone could answer this for me as I can't find an answer anywhere.
I was just wondering whether to buy the Google USB C cable that is stated to transfer at USB 2.0 speeds (480Mbps) or whether to buy a faster USB 3.0 (5Gbps) or 3.1 (10Gbps) cable (A to C).
I've found a few compliant USB C cables including a Belkin USB 3.1 A to C cable that transfers at 10Gbps and was hoping to take advantage of the USB 3.1 ports on my new Z170 based motherboard.
Thanks

I do not believe the port in the Pixel C is USB 3.0. Therefore, it wouldn't be necessary to get a USB 3.1 cable. It should still work, but you wouldn't exceed USB 2.0 speeds, which is probably why Google's cable is only USB 2.0.
Thanks for the response.
Is anyone able to do a quick transfer with a USB 3.0/3.1 based Type C cable to see if it maxes out at USB 2.0 speeds.
It would be much appreciated.

Most tech sites report the Pixel C has USB 3, but the fastest read speed I can get on a USB-C /3.0 flash drive is 27MB/s which leads me to believe even tech sites are confused and don't understand that USB-C does not automatically mean USB 3.
I think it was confirmed by Benson Leung, in the Reddit AMA, it's full host/client USB c spec so it's full speed port. Maybe another way to test would be to mount a USB 3 drive to pixel and storage benchmark it
I thought that the USB 3.1 host and client related only to the ability to charge the Pixel C as well as the ability to charge other devices from the Pixel C and to use the USB port for other devices such as an ethernet adapter.

That's pretty much what I did. A USB 3 USB-C MicroSD flash drive. On my PC it reads at 80MB+, on the Pixel it is 25MB
I'm a bit confused now.
Recently I read a review by Benson Leung on a USB 2.0 A to C cable here http://www.amazon.com/review/R1AF6ZHBZRQFHV/ref=cm_cr_dp_title?ie=UTF8&ASIN=B018HUOMYE&channel=detail-glance&nodeID=2335752011&store=wireless on Amazon and at the end of the review states:
In conclusion, this is a Good cable for your Nexus 6P/5X to use with all of your older USB Type-A chargers, hubs, and PCs. It also works great with Chromebook Pixel 2015 and will work great on USB Type-C spec compliant devices to come! However, it is NOT a SuperSpeed USB 3.1 5gbps cable. Look elsewhere if you are specifically looking for a 5gbps cable for use with MacBook or Pixel C.
Is this implying that the Pixel C is capable of USB 3.0 speeds, but perhaps not at the moment?
Or is it just a typo as a Superspeed USB 3.1 cable should be capable of 10Gbps and not 5Gbps (USB 3.0).
That is interesting. I'd suspect he'd know what the C is. I however, have never gotten more than USB 2 speeds out of it.

Use USB-C On the go (OTG) and power charging simultaneously?

Hello out there.
Has anybody figured out a way to using a USB-C On the go (OTG) adapter for OTG functionality, and get power charging working simultaneously?
I have seen some people have had success using USB Y cables with micro-USB OTG, but haven't read anything confirming this works or is even required using USB-C compatible phones such as the Nexus 5x. I saw some Startech Y cables are available for purchase and some dodgy homebrew setups which I wouldn't attempt personally!
I have a USB-C OTG connector and a mains powered USB 3.1 hub. With this setup I can charge or use USB devices successfully on the phone, but it's one or the other, not at the same time. I'm forced to choose the USB charging option on the phone to switch between the two.
Any thoughts or experience on this using a Nexus 5x or similar? Cheers!
And sort of related - new Macbook can drive an external display over USB-C. Can Android / Nexus 5x?
I have also been looking for this - to allow always-on wired ethernet. Have not found a solution. My Nexus 5X will last for several days when the ethernet adapter is externally powered by a hub, however. The trick is to make sure nothing is running except essential comms and email when on standby. The new Marshmallow Developer mode allows this, by selecting most apps to be 'inactive' during standby and only allowing one app to run at a time. My phone runs for weeks at a time in standby when there are no ethernet connected and no WiFi/4G. Connecting wired ethernet cuts that to about 7 days, depending on email notification activity.

I'm on the same boat, needing to have a Nexus 5X connected via Ethernet and powered.
So far I've tried:
- a USB Type C to USB female OTG cable
- a USB Type C to microUSB adaptor via a Dell powered USB OTG cable and a powered Acasis OTG USB Hub
but I got the same behaviour:
- USB OTG works with Ethernet and no power
- USB C to USB OTB HUB/powered OTG adaptor = power, but no OTG functionality
Is there a an updated USB C OTG pin out diagram available ?

Yes and Yes.

With the right hub, is it possible to charge and OTG Pixel C at the same time?

Hi,
I have tried with Micro USB Nexus 6 and I know that they do not charge and support OTG at the same time. Is it possible with Pixel C to use OTG and charge in parallel?
Thank you.

Yes. Just about any USB C hub with pass through Power Delivery charging will do what you want. Almost all USB C hubs that advertise charging Macs, Chromebooks, other laptops, will work for this.

Having trouble with OTG and PD charging in Pixel C

Recently I found plug in any OTG devices or PD charger in Pixel C will have a same issue. These devices will only works with one certain face of type-c plug and won't work with another face. But type-c plug should work with two faces plug in to devices. Is I broke my Pixel C's type-c port or it is a compatibility issue.
PS. I know usb type-c is using a CC pin inside the plug to recoginze the current face that plug in.

Sounds like either you have a dead contact on one side of your plug or some corrosion maybe
