USB type C and Quick Charge 3.0

This is interesting. Basically this guy is saying USB-C doesn't support proprietary charging above 5 volts which is why Google didn't use Quick Charge for the Nexus 6P.
Maybe this is also why Samsung didn't use USB-C because they wanted to safely use Quick Charge?

This is going to be posted all over and its basically nonsense. The current QC 2.0 over micro usb are also using 9-12volts. And micro usb also only supports 5v. So. It's no different then it's ever been.
Get a QC3.0 compatible charger/cable and be done.

Quoted for truth.
Quickcharge checks before sending down higher voltages. It's fully backwards compatible even if it's not part of the USB specs. There is no additional danger from what you had before.

This is total BS!!
I have the HTC 10 in my hands, it is quick charging with no issues.
Also, take the Apple Macbook as an example, the laptop uses an USB-C port to charge, it inputs 14.5V with 2A.
If the USB-C meets the USB-Power-Delivery standard, it can transfer up to 100W of power. Don't believe the BS article.
Edit: It seems that Qualcomm uses their own implementation, but still it is transferring voltage over 5 volts

Is the article supposed to say that not all USB-C cables can support it? Maybe the cheap ones can't?
Didn't Amazon just yank a bunch of cheaply made USB-C cables from their marketplace?

Here's my take. I have always been under the impression the device dictates the watts and volts not the charger. The charger has a range it will draw power, and the phone tells the charger how much it needs. QC standard is UP TO and is not absolute. So if the device tells the charger I want 15W/5V that's what it'll get.

I've been trying to research and I have come up with a conclusion. This is only my opinion, but I have based it off of hours of research. Please feel free to correct me if I am wrong.
Is QC QuickCharge 3.0 charger going to hurt my phone or anyy other devices I may plug into it?
Best I can figure is no. QC 3.0 chargers are designed to only fast charge if it is connected to a QC 3.0 device. Before it starts fast charging, it does a negotiation withh the device to verify if it supports QC 3.0. "Also, since Quick Charge is compatible and interoperable, a certified adapter can be used with a non-Quick Charge device, though the fast charging benefits of Quick Charge will not be available. " : Source
Can my HTC 10 be charged qith a non QC 3.0 charger?
The simple answer is yes. If you use one of the many non-QC 3.0 chargers that you have laying around, it will charge your phone just fine. This is as long as you use a compliant cable with the 56k ohm resistor. More on that next.
Does it matter which USB cable I use?
This one is tricky. I do not have an HTC 10 yet, but I have heard that it comes with a USB 2.0 Type A to USB 3.0 Type C cable. I can't find the source now, but it was in the Mega Thread. If this is true, than you should be able to use any cable this spec or better. By better I mean a USB 3.0 Type A to USB 3.1 Type 3 cable should work fine. The most important part is that the USB cable MUST have a 56k ohm resister. There have been some cheap cables using a 10k ohm resister that could cause problems. These problems could result in the port on the device or the charger getting damaged.
Will the HTC 10 work with a USB-PD charger?
Well first, USB-PD stands for USB-Power Delivery. This is the new USB fast charging standard set by the USB gods. This technology allows devices to receive more power and thus would allow a phone to charge more quickly. This is NOT the same as QC 3.0. QC 3.0 is a proprietary charging system and only available on certain Qualcomm powered devices. So can the HTC 10 use USB-PD? My guess is no but I could be wrong. According to GSMArena, the HTC 10 has aa USB 3.1 port. USB 3.1 supports USB-PD for quick charging. This would lead me to beleive that the HTC 10 supports both methods of fast charging. Unfortunately, I have been unable to find anywhere on HTC's site that specifies what the USB port actually is. My guess is that it is USB 3.1 compatible but not USB 3.1 compliant. by USB 3.1 compatible I am saying it will do everything that a compliant port will do except the USB-PD charging. We actually know that the port is not USB 3.1 compliant as the USB standard does not allow the method of fast charging that QC 3.0 utilizes.
I hope this helps to clear some things up. Once again I am no expert, but this is the way it appears to work as far as I can tell. If there is anything that I have wrong, please let us know and I can change it.
Thanks

Yes it is compliant.... This is why USB 2.0 devices were able to have quick charging. The type C port is no different.
http://www.anandtech.com/show/8539/...ard-device-class-v10-specifications-finalized
Version 3.1 now supports 5 V, 12 V, and 20 V on the pins to allow the higher power output without excessive current, but even the current has been increased to a maximum of 5 A which is much higher than before.
The HTC 10 does support 3.1 as their tech page says it support USB 3.1 gen 1

Your kinda missing the point. The the HTC 10 is NOT compliant. It goes against the USB-C spec, "These, and any charger you see that supports QC3.0 over USB Type-C, might be QC3.0 certified but they're not following the USB-C spec." Source. If you are not following the spec, you are not compliant. You can be compatible without being compliant. Anyway, I don't care if you want to call it compliant or not. What I am getting at is that it most likely does not support the USB Power Delivery for fast charge. And if it does not support USB-PD, than it is not a USB 3.1 compliant port. USB 3.1 standard includes USB-PD Source. So the HTC whitepapers say it is a USB 3.1 port. That is great. If it does USB-PD fast charging, than that would be awesome.

Benson assumes it isn't compliant because
1. He doesn't have the device.
2. He can't find what USB port is being used
So since he can't find this information that he can't recommend something is on the basis that he doesn't want to approve something because he doesn't know. I bet if he saw the information I just showed and he sees the white paper he'll change what he said.
Why would it not be compliant when USB 2.0 devices can charge using the exact same voltage yet a 3.1 port can't? Think about it for a minute. It would be cheaper if they were not compliant to NOT use, and not give a QC 3.0 charger... Much like Google did with the 5X and 6P probably to save on costs.

Okay, I wait for him to get the device then. You still can't be compliant and break the rules though. You can be compatible though. As for the 5x and 6p, they support the USB-PD fast charging. This kept google with the USB standard. HTC chose to go with the QC 3.0 proprietary solution most likely because it works better. QC 3.0 only has to work with select QC devices and therefore can be tailored to exactly what they need. USB-PD will have to work across multiple device types from multiple manufacturers. This leaves room for inefficiencies. That would be my opinion.

That shows to me it doesn't support USB-PD 2.0 which supports up to 20V to the pins
http://www.anandtech.com/show/8539/u...ions-finalized
When USB was first introduced, the thought was that it would be primarily a data interface, with a limited amount of power delivery which was generally used to power the electronics of certain devices. The initial specification for USB only had provisions for 0.75 watts of power – 150 mA at 5 V. USB 2.0 bumped that to 500 mA, or 2.5 watts, and USB 3.0 specified 900 mA at 5 V, or 4.5 watts. All of these specifications allow for power as well as data transmission at the same time. In addition, there was also a Battery Charging specification which allows up to 1.5 A at 5 V for a maximum of 7.5 watts of power but with no data transmission available. The jump from 7.5 watts to 100 watts of the new specification is a huge increase, and one that cannot be done with just an amperage increase on the system as was done in the previous versions of USB. Version 3.1 now supports 5 V, 12 V, and 20 V on the pins to allow the higher power output without excessive current, but even the current has been increased to a maximum of 5 A which is much higher than before.
That right there makes it possible for QC 3.0 to happy while staying PD 2.0 compliant.

Everything you posted is usb-pd specs. I agree. The difference is that qc 3.0 uses the data pins as well where usb-pd does not. They are two different approaches to achieving a common goal. While QC 3.0 does not apply more power than the spec allows, is does supply the power in a way that goes against the spec.

Do you have the papers showing this? I haven't seen anything that says it goes through the data channels.
Either way the fact that PD2.0 rates 20V debunks the cable or connector can only handle 5V arguments.

I'm not sure if it was said but USB 3.1 =/= USB 3.1 Gen 1.
Especially in response to "The HTC 10 does support 3.1 as their tech page says it support USB 3.1 gen 1"
USB 3.1 with it's 10Gbit/s speed along other specs, features etc. was originally called USB 3.1.
USB 3.0 with it's 5Gbit/s speed along other specs, features etc. was originally called USB 3.0.
USB 3.0 =/= USB 3.1
Got that?
USB 3.0 > USB 3.1 Gen 1
USB 3.1 > USB 3.1 Gen 2
Why? Because retards.
Also marketing wankers. "Looky looky, our product has USB 3.1 Gen 1 which means it's better than USB 3.0."
Same story happened with LTE and 4G. Carriers/ISP's begged/forced the 3GPP to allow them to call LTE as 4G when LTE-Advanced is what 4G is.. LTE is more like 3.9G
And if I'm not mistaken, you Americans also had 3G HSPA+ disguised as 4G when it's actually 3.75G? And when LTE rolled out they just called it LTE.
tl;dr? HTC 10 has a USB 3.1 Gen 1 port or in other words USB 3.0.

USB 3.1 gen 1 only works with type C connectors on eqch end to get those speeds. That's why you don't see USB 3.0 type C cables or USB 3.1 A to C cables.
My laptop makes that distinction as well. All my ports are 3.0, but my type C ports are USB 3.1 gen 2.
Even Monoprice for example. All their C to C are 3.1, but as soon as one is a different connector they are all 3.0.

The USB spec etcetera is a deep rabbit hole and the renaming of USB 3.0 didn't help things at all.
You don't need type C-C cable for USB 3.1 Gen 1. USB 3.1 Gen 1 is what we used to know as USB 3.0. You can have USB 3.0 or USB 3.1 Gen 1 with USB A-A or A-microB (the weird 3.0 micro) or A-B or A-C or C-C or whatever the variation you can think of.
The reason you don't see USB 3.0 C-C cables is because chicken and the egg. The original USB 3.0 spec was released before the type C..
Type C was developed at the same time as the now finalized USB 3.1 spec, which absorbed the original USB 3.0 spec as USB 3.1 Gen 1 and the USB 3.1 we knew before is now known as USB 3.1 Gen 2, and was (C spec) released alongside the USB 3.1 spec which it supplements.
No USB 3.1 A-C cables? Ahem. http://www.belkin.com/us/p/P-F2CU029/
Also, just please try and forget the USB x.x with the type C.
Type C is type C. It is a physical connector, it's a cable/connector standard.
Just like mini B or micro B or B or A for that matter..
USB x.x is a technology standard.
USB-PD is a technology standard.
They are not the same thing.
They are not dependent on each other.
In other words, you can have type C with USB 2.0 if you so wish, look at the Nexus 5X and 6P..
http://www.usb.org/developers/usbty...ge_Product_and_Packaging_Guidelines_FINAL.pdf
Please note the following:
USB Type-C™ is not USB 3.1
The USB Type-C™ cable and connector specification is a supplement to the USB 3.1 specification, however USB Type-C™ is not USB 3.1.
These terms are not interchangeable.​
USB Type-C™ is not USB Power Delivery
USB Power Delivery is a protocol/hardware solution that increases USB power capabilities up to 100W.
These terms are not interchangeable.​
If a product features USB Type-C™ it does not necessarily support USB Power Delivery and/or USB 3.1
Device manufacturers can choose to support USB Power Delivery and/or USB 3.1 performance but it is not required for USB Type-C™ products​

I didn't know about this but today was the first time trying to transfer files from my HTC 10 to my pc through the usb 2.0 port using the official htc cable that came with the phone and it was painfully slow. I have 3.0 ports on the back of my pc but I know it shouldn't be this slow. I'm transfering files to a Samsung 850 EVO SSD. Stuff that should only take 5-10 seconds to transfer takes like 3-5 minutes.

I have fast file transfer working on an A-C USB 3.0 cable (not USB 2.0)
You have to enable "charge mode" then the option is available.
Fast file transfer doesn't work in normal MTP mode.
BTW Monoprice has high quality cables for very inexpensive.

I bought a USB3.1 gen 2 cable from Amazon (support for 5Gbps transfers for the HTC 10, but can also do 10Gbps for future-proofing), and connected it to the USB3.1 port on my motherboard (ASUS x99-m WS), but speeds are still definitely not USB3.1 gen-1 5Gps.
Transfers may be working at USB3.0 speeds (which does ~1-1.25Gbps IIRC?), but transfers are definitely not working at USB3.1 gen-1 5Gbps speeds.
I tested this by transferring a 700MB file from PC to phone internal storage (not SD card), then the same file back to PC, and it transferred slowly.
Transfers were slow even though "Fast file transfer" selected by going to USB charge mode and enabling Fast file transfer.
Does anyone have USB3.1 5Gbps transfers confirmed working? What cable/mobo are you using?

[UPDATED] Moved my comment to a separate thread here.

My computer won't even recognize when I have the phone connected via a usb-c to usb-c cable. Works fine usb-a to usb-c, but not when I go to either of the 2 usb-c ports.
Is there a different driver i need for my computer to recognize the phone on usb-c?
(it's a usb-c to c cable provided with a pixel phone, so should be decent quality)

For OTG accessories, and some attachments such as cameras, the phone is the USB host.
'Conforming' USB-C to micro adapters (listing the '56k resistor' ) will not work. Tells the phone to take a charge, it is not host.
Look for adapters that are non conforming, better yet are 'OTG' compatible.
One is:
Meenova
USB 3.1 Type-C to MicroUSB 2.0 Female OTG Adapter, Gray, pack of 2
My micro USB thermal camera, 3d camera, and USB host cables work. There are other brands as well.
## This message is NOT about connecting phone to a charger or PC ##
I'm currently (partially successfully) using the following in an attempt to use an External 1TB Drive as a portable backup solution for travels:
Type C Adapter, RAVPower USB C To A Female OTG Cable, USB-C On The Go Convertor for New MacBook and Other Devices with Type C USB
I can get images onto the phone's internal 128GB card (Lexar Professional 1800x microSDXC 128GB UHS-II W/USB 3.0 Reader Flash Memory Card - LSDMI128CRBNA1800R) via OTG and Card Reader ...I cannot get them off of the internal on to the External 1TB via the OTG cable.

Problem with old HTC M8 Charger
At home I use the charger that came with the phone.
At the office, I was planning to use the HTC charger that came with my old M8, maybe not quite as fast.
But strangely enough, when I do that, the charge light turns on and off every couple of seconds, it wakes the phone, and it doesn't charge.
A Belkin 2.1A charger I had works fine though. Go figure.

I don't think the HTC 10 is compliant with USB-C Power Delivery (Such as the Nexus 6p) do deliver the rapid charging speeds of up to 3A via a USB-C charger and a USB-C to USB-C cable. I remember reading up about it of an article referencing Benson Leung (not the 1st one, but most recent one). He said the LG G5 is compliant with the Power Delivery achieving the 3A max input. But the HTC 10 only achieves 2A.
I can about confirm this because I have 2 USB-C wall chargers, one by Cheotech that gives me around 1600mah-1700mAh, and one by iClever, which gives me the same speeds. My RavPower Turbo Series Powerbank with the USB-C port and the max of 3A output gives me the same 1600-1700mAh speeds of input into the HTC 10 as well.

I've tested a Samsung adaptive fast charger from the s7 and s6 with the OEM cable and a ravpower A to C cable and it shows Rapid Charging when plugged in.

MTB Adapter
@lsblack
adapter must use display port protocol (I think). This USB-C to HDMI, USB3.1, and USB-C (charging port in only) works. Found on eBay.
USB Type C Hub for Macbook Pixel USB C to HDMI USB 3.0 & USB-C Charging Port
Brand MyTripleBest
MTB--USB-C-A.
This adapter didnt worked with my HTC 10, it showed that video was conected but there was no transmition over to the TV or monitor, or am i doing something wrong? i mean i tried everything, and it didnt worked >.<, or maybe i got a defective unit? also, are you connecting into a 1080p, 2k or 4k TV/Monitor? maybe is that...

Which charges faster USB C or USB 3 .0?

I just bought my first Google pixel tablet with a USB C charging point. Is it faster to charge USB C to USB C?
Or is USB 3.0 2 USB C the same speed?
Thanks

I know with my lg v20 if I use my USB c pd charger with it. It charges faster than my 3.0 USB A to USB c charger. So I would guess same holds true with the pixel c.

USB-C and USB 3.0 are two completely separate things. USB-C is merely a connector type. The default protocol for USB-C is USB 3.1, but if anything in the connection is incompatible with 3.1 then it will reduce down to whatever the lowest is. For instance using a USB 3.0 cable on a 3.1 connection results in 3.0 speeds/power. Likewise, if you use a tablet/phone whose physical port is USB 2.0 with a 3.0 cable it will still only go at 2.0 speeds.
What really matters here is your power source. The Pixel C supports USB Power Delivery for fast charging. The included charger is not PD-capable and will charge at 15W ([email protected]). The Google 60W USB Type C charger (included with the 2015 Chromebook Pixel) will charge the Pixel C at 24W ([email protected]) Another thing to keep in mind when considering chargers is that Qualcomm's Quick Charge isn't the same as what the Pixel C uses and likely will always default to 5V/2.4A charging so make sure you use a PD-capable charger if you want to get the fastest charging speeds.

That's very informative. How quickly does the pixel charge when at 12V/2A?

All very useful information. Thank you.
I have a feeling that fast charges can eventually cause damage to a battery or at least reduce its life expectancy.
I don't know why but I have the impression that slower charging – if one isn't in a hurry, such as overnight will eventually give longer battery life – especially interesting in a unit which doesn't have a user rechargeable battery.
Got any comments about this?

I would suggest this reading: http://www.fpvforme.com/charging-lipo-batteries/

Just make 100% positive you're buying a good USB C Power Delivery compatible charger+cable, if not you risk damaging your Pixel C.

Question PCIe 2-Port USB3.1 Gen2 Card

I have tried USB-A to USB-C cable on my computer but the only thing that works with the cable is windows file transfers, in fastboot it just never connects to the device, i have used my GFs PC that has a native USB-C port in the front to do my fastboot commands and it works just fine.
My PC dont have USB-C and my motherboard is this : Asus Tuf Z390 Plus Gaming Wifi
The case is a Be Quiet : PURE BASE 500 Black
I have tried all the back USB-A ports and the 2 in the front same results.
I wonder if this PCI-E Card can help me use my fasboot commands on my computer or is just a faster transfers i get with it?
ST Lab PCIe 3.0 USB3.1 2-Port (Type-C)

Tried using another A-C cable? Might be the cable itself is faulty

You might want to try out another cable. Sometimes they just suck.

I have 10 different cables that are USB-A to USB-C, maybe they all suck, but the original Pixel 6 Pro USB-C to USB-C is good, maybe you can advise me on a good USB-A to USB-C cable?

Anything by Anker. Edit: Be aware that last I looked, they also sell USB 2.0 USB-A<->USB-C cables, so I just want to give you a heads up to look out for that and I'm sure you'd want to only buy a USB 3.0 USB-A<->USB-C cable.
Also, I don't know if the recommendation is still the same, but it was always advised in the old days to prefer USB ports that are built into the motherboard - sometimes even more specifically on the back of the motherboard (for desktops). I know this doesn't help you, but just "let the buyer beware" that using an add-on USB-C card could also cause problems.

Do you have the latest USB drivers installed?
And like others have said, try different cables. Can't tell you how many times I've seen this problem solved just by using different cables.

Its not your hardware, its your operating system. Try a better one, i.e. Linux.

I highly recommend Anker cables like this: USB Type C Cable, Anker PowerLine+ USB C to USB 3.0 Cable (6ft), High Durability, for Samsung Galaxy Note 8, S8, S8+, S9, S10, Sony XZ, LG V20 G5 G6, HTC 10, Xiaomi 5 and More.
Double-check Anker's site too in case they have a better sale price right now.
