[Q] dual usb cable to overcome pc usb limitation possible?

Would a dual usb cable work to get a faster charge from a pc or other device that has more than one usb port available?
Something link amazon item number B00439567Q
Typically these are used with hard drives to overcome this limitation, so I'm wondering if it would have the same effect on the Galaxy Nexus.

Probably not. The nexus isn't really a hard drive, it's more like another computer, and you typically can't connect pc to pc via USB... The limitation is that the sd is actually a virtual sd, and you're actually connecting to the whole OS via USB...
You're better off mounting a stick drive and then using that to transfer files to your PC...

Guess you didn't read his post... He's talking about using dual USB for power.
OP, I think it'd work. USB only puts out 500mA, so putting 2 together would improve charging times more like a wall charger that does 1A. No guarantee how the PC would handle it though.
Is your phone not charging from a USB port? Because mine does... Slowly, but it does...

What about USB 3 it has a lot more power.

From what I have read usb3 is .8a while a single usb2 is .5a. So .3 more a. Unfortunately I have no usb3 hosts, so that not an option.
Anyway thanks martonikaj, I will change my cables and hopefully get a more timely charge.

Unless you short the data wires on the usb cable or use a kernel that has full usb charging enabled it won't matter how many ports you use. The phone detects the data connection and reduced charging to the slow charge to prevent overloading a pc usb port.

Maybe flash a kernel that has the USB Fast Charge mod enabled?

USB 3.0 OTG cable

According to the specs, the G Pad supports USB 3.0. I assume that this can be used when connecting to a PC that supports USB 3.0. I'm wondering if OTG devices (e.g. external drives) can work at USB 3.0 speeds with the correct OTG cable. Does anybody know?

All it means I believe is that it's USB 3.0 compatible, which every USB 2.0 device is compatible. It does not have a USB 3.0 plug so it can't achieve the same transfer speeds of a USB 3.0 device such as the Note 2?
Since the tablet is physically incapable of accepting the cable USB 3.0 devices, you won't get USB 3.0 speeds from an external device connected via OTG.

I don't follow you. It's the other way around. USB 3.0 devices are compatible with USB 2.0 devices. It doesn't make sense to say that the G Pad is capable of USB 3 unless it can achieve USB 3 speeds. I just don't know in what situations it can use USB 3.

Just looked at LGs web site and the specs say the GPad is USB 2.0 only. It'll work with 3.0 devices just at 2.0 speeds. OTG works, tried with a USB thumb drive.

Yes and no, poor wording, I meant what you're saying :laugh:
But yeah physically impossible for it to support a 3.0 device in 3.0 form without the extra pins that USB 3.0 uses for transfer.

I don't know where I got the idea that the G Pad could support USB 3. Must have been an incorrect spec that I saw somewhere. Looks like you're correct that it doesn't support USB 3.

hi, have you already tried connecting a gamepad on the otg cable? does it work? or is there an app needed for it to work?

Fast File Transfers

I have a usb c to usb c i-orange cable plugged into my computer and when I try to enable Fast File Transfers I get "USB 3.1 Unavailable. Make sure you're using a USB 3.1 cable. The other connected device needs device also needs to support USB 3.1" My ASUS Maximus VIII Hero motherboard supports USB 3.1 and I have the right cable. Has anyone actually gotten this working? Running Windows 10 64 bit and have the latest drivers/firmware for my system.
Thanks
EDIT
****Nevermind**** BE VERY CAREFUL ORDERING i-Orange CABLES on AMAZON.*******
When you select the USB 3.1 i-orange cable there is a list of color and size options below. All of them but 2 cables are USB 2.0 Type C connectors and not USB 3.1 The usb 3.1 type C cables are only 3.3ft, the longer cable I chose is actually a USB 2.0 Type C cable.
The industry is making type C a nightmare to deal with, there should only be 1 type C to type C cable.

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)

HTC 10 usb 3.0 problems

Hello, I've just purchased HTC 10 from T-mobile in Poland. I installed HTC Sync Manager, but every time I connect the device to usb 3.0 port, my Windows 10 file explorer hangs and I can not use the device (nor can I do it through Sync Manager.) I tried downloading only usb drivers and selecting the option to fix corrupt files, but it didn't help either. Weird thing is, that there is no problem when using usb 2 port. Any ideas on how to fix it?
PS I've never had any problems with using the usb 3.0 port with my LG G3

I had this issue when using None Intel USB 3.0 ports at the front of my PC. Do you have any intel USB 3.0 or USB 3.0 at the back of the PC you could try and see if it works?

According to what I I have read, if you are wanting to activate USB 3 mode in the HTC 10, what they don't tell you is that it is actually USB 3.1, and you must have USB 3.1 ports on your PC to connect to, otherwise it will only connect at USB 2 performance even if you plug it into USB 3 on your PC. You can't enable the USB 3 mode on the HTC 10 unless it senses being connected to a USB 3.1 port. I speculate that is why the cable HTC ships with the HTC 10 is actually a USB 2 cable with a USB C (3.1) connector on it. I was rather disappointed to learn this. I have USB 3 on my PC, but not USB 3.1, so I can't use the USB 3 mode on my HTC 10. My prior Galaxy S5 had a micro USB 3 connector and (before it eventually failed to work) I was able to transfer files an appreciable amount faster via USB 3 between it and my PC.

Exactly as you said, I tried disconnecting usb 3.0 ports at the front (I have zalman z9 u3) and using the ones directly from mobo and it worked. Any idea why is that?

My best guess is front USB ports don't have enough power to push data to the htc 10
Or the front USB ports none Intel are bugged when using this device.

USB to Note 10+ connection drops... Resolution?

Given:
I have a brand new powerful PC with USB 3.2 Gen 2 Type C, USB 3.2 Gen 2 Type A, USB 3.1 Type A, USB 3.0 Type A (and USB 2.0 Type A - internal in the tower) connections. I have also replaced all my USB cables with "SuperSpeed" 10Gbps throughput cables, being sure to get any and all Type C -> Type A adapters to also have the "SS" SuperSpeed Logo and the correct circuitry/leads to adhere to the higher standard. (Until I got the new cables I was still getting warnings when I plugged my Verizon Note 10+ 5G 512GB into an older cable connected to the 3.2 Gen 2 port that I was connecting the device into an older slower USB port, which is now resolved...)
I have started using Scrcpy to have my Note 10+ screen shown on the computer screen. Everything is lightning fast. I even tried using one of those cable to connect to an external SSD and tried copying several gigs of files across and CANNOT BELIEVE how fast everything is copied!
My PC is a PowerSpec G464 with and AMD Ryzen Processor (motherboards for Intel CPU's do not yet support the PCIe 4.0 slots which I do have on this system):
http://www.powerspec.com/systems/system_specs.phtml?selection=G465
It is my understanding that these motherboards have all USB connections at some point going through the same controller. Ideally each USB port would go through it's own controller and that's why such add-on PCIe cards are much more expensive and never use a PCIe x1 connection but typically a PCIe x4 slot instead. I have an add-on USB card but stuck with a cheaper one that has 4 ports (all of course sharing the same controller) as I wanted to use a PCIe x1 slot only.
Problem Statement:
So here is my dilemma. The cable connections for the Note 10+ are nice and tight, but every couple of minutes it disconnects once - and then reconnects almost instantly. It is a weird issue and kicks me out of the Scrcpy app which I relaunch - but how to resolve?
(FYI - I have not tried using any of the internal USB 2.0 ports. Also, some of my other devices on the USB SuperSpeed ports would often connect and disconnect periodically but that was all resolved by replacing the cables as mentioned above.)
Ideas? I'll try anything anyone suggests and report back. Is it possible the Note 10+ cannot handle ports expecting a 3.2 Gen 2 connection (although I know they are supposed to adjust automatically)?
