[Q] USB OTG: usb1 found, cannot use keyboard

Hello,
I have a USB OTG cable and dell keyboard that I have tested and work in OTG mode on a Nexus 7, however i cannot get them to function with my HP Touchpad 32gb, running CM9 2.6.35, built on Sun Oct 28.
The device recognizes when I plug in anything via USB, but only as a generic Linux USB hub, and not as any particular device. Are there any steps to take to debug this? Has anyone had experience with this type of an issue?
Thanks for your help,
Cory

I don't know if this is the issue, but I know the touchpad doesn't support OTG like the the Nexus does. I think you need a Y-adapter + OTG to provide power since the micro usb port doesn't give any power to the device you connect. Someone correct me if I'm wrong though.

Apparently even a powered USB requires a powered Y cable to be properly recognized. I hacked together a quick Y cable manually, by splicing in another USB cable's power and ground (Red and black) to the respective locations on a female USB cable. Works as expected.
I am now communicating with an Arduino over Serial
Thanks!

Read this thread, should give you all the info you need:

Basically the Touchpad has OTG but it provides no power.

Agreed. I think people just are not stating reality regarding the ability to charge and use OTG Hosting to USB devices at the same time.
My goal here has been to attach a flash drive with video/audio media and play & charge on long flights. It looks like play, charge are mutually exclusive on my beloved TouchPad.
I've asked for the specific confirmation of this from this YouTube but have never had the poster reply:

There are devices out there that have very advanced micro USB device implementations. Sadly the HP is only superficially supportive.
I for one cannot wait to get my SGN2 smart dock which offers:
Charging
OTG (x3 USB)
Audio out
HML HDMI out

cable for Android Auto

Any one using Android auto on this phone? which cable are you suing.
I am using a USB to C converting charger right now, but when I use it, phone discharges. may be the power is not enough to charge the phone.
Any special cable or setup needed?
please suggest

As I assume you are talking about Android Auto Google appwitch doesn't need any cable bocouse it connects wirelessly with Car with is capable of Media Interface and Android/iPhone plugin (cars from 2016 - few BMW, Bentley, Audi -no Mercedes)

There is no wireless option for android auto. You need to use a cable to connect to your head unit.. At least till date

Problem is the port that comes with your car doesn't support quick charge as it is a standard 1.5Amp port and not a type-c. Your best bet would be to get a USB type c - usb 3.0 cable from Anker or any other seller but be sure it meets usb type c specs. If you are buying on amazon make sure you read the reviews from Benson Leung who is an engineer from google.
I have been using anker cable and its working fine.. Although it wont charge much when using navigation but atleast it wont discharge

I have USB type c to USB 3 cable, when I connect the cable directly to the car and use navigation it works fine, but when I connect through android auto, it wont charge at all. i am fine if it wont discharge. so your cable will not discharge using android auto?
Do you think this will be useful?

since my phone didnt come with the type c adapter, nor the usb a to c, i had to make something.
i went out and bought a usb type c to type a female (it was made for some apple laptop), then cut up two usb type a male cables and wired them together color to color. i plug one end to the usb type c adapter, and the other end to my android auto unit and it works fine!
i have noticed some vehicle that come with android auto only throw a 1.0amp through the usb port, while aftermarket radios (pioneer, kenwood, etc) come with 1.5 or even 2.0 amp usb ports.
my phone will not charge on the 1.0 output that the stock vehicles have, and if im using nav i will definitely see a drop in battery.

Anyone using USB c to A 3.0 or 3.1 cables successfully with their note 8?

I have tested with several cables and multiple manufacturers and multiple computers and cannot get a USB3.0/3.1 cable to keep a connection with the PC. USB 2.0 works fine.
I called Samsung and they are telling me that they only support the cable that came with the phone, which is a 2.0 cable. So they don't even support the 3.1 standard they advertise. I am about to return the phone over this. I have not found anyone else having this problem, but I have also not heard that anyone is using USB3 successfully either.

Yes I have success
I transferred over 7gb of data from a pc to a Note8 (sandisk 400gb Sd card) using a choetech USB c 3.1 gen 2 superspeed cable. The pc has superspeed ports (Alienware Area 51). Did not have any issue the two times ive connected the note 8 to a pc.

I have a type C to 3.1 type A cable from Anker, but have only used it on 3.0 ports on my laptop and desktop, definitely works super fast (even flashing the firmware with Odin - only takes a few seconds for the full package). I ordered 2 different cables though, one was apparently charging-only and didn't even work to fast charge.

I was planning to buy Anker Powerline Plus USB - C to USB A 3.0 cable. Isn't the cable good enough to fast charge the phone? Doesn't it charge as fast as the regular one (which came in the box) does? How much max current can be drawn using anker cable to charge note 8 and how much time does it takes to fully charge the device with anker cable compared to the original one?
Kindly provide these details, as I am confused whether to buy this cable or not.
TIA..

I have Trilink braided USB-C 3.1 cables that I bought on Amazon. They work perfect, super fast transfer speeds, and my phone charges the same as with the OEM cable that it comes with.

Does your PC actually support USB 3.0+ and are the ports setup correctly? Too many motherboard manufacturers poorly implemented USB 3.0 on their rushed motherboard, and Microsoft had to suffer the long end by providing poorly patched drivers because the boards never had the proper port insulations.

Question Xiaomi Mi 11 Ultra usb type version ?

is it : USB Type-C 2.0 ?

according to gsmarena it is yet again ver 2.0.

But can you use a USB C dongle to convert to HDMI for output?

Really interested on it

The 10 Ultra has no output on usb to hdmi connector. I tried it as I wondered after coming from a p40proplus which had a desk top mode. I imagine the 11 will be the same as it promotes the desktop app to share it's display like the 10.

You mean in wireless mode?

Yes，USB 2.0

It is still USB 2.0

Such a shame. Imagine transferring 500 GB of data with 30 MB/s rate.

usb 2.0, hahahha~It doesn't deserve to be called “安卓之光”

It's really disgraceful to use the best CPU money can buy , best ram, fastest ufs storage , best display , best charger and then go cheap on something like a USB 2.0 port.....
Someone who thought this was a good idea should be fired....

Yeah, i really don't understand why they put an usb 2.0 port. For a 2021 premium phone it's a nonsense.

I have not received my Mi 11 Ultra yet, but I believe it should work when using a Displaylink USB to HDMI Adapter and installing the Displaylink App on the phone. With USB 2.0 it should work fine for resolutions up to Full HD.

The USB Type-C Specification states that it must support at least the following standards, otherwise a Type-C connector cannot be used:
• USB 2.0 Specification
• USB 3.1 Specification
• USB Power Delivery Specification, Revision 2.0 (3.0)
• USB Billboard Device Class Specification, Revision 1.2
• USB Battery Charging Specification, Revision 1.2

I already tried it.
I had to power the USB C adapter then I plugged the Displaylink adapter to the USB C adapter.
It would not work without power.

Usb 2.0 was released in April 2000 and some clown at Xiaomi thought they should still use it in their ultra flagship 2021 phone ....
Words fail me...

I thought Xiaomi devices are 2.1 not 2.0

I use this
CableCreation USB HDMI Adapter(DisplayLink Chip), USB 3.0 to HDMI External Display Graphics Adapter Compatible with Windows 10/8.1/8/7, White https://www.amazon.com/dp/B07DX33L5...abc_D4RSEZX9P70E6V3KSFR4?_encoding=UTF8&psc=1
You need any USB C hub with a USB B A 3.0 hub and PD pass through.
Something like this
USB C Hub - TISOFU USB C Adapter with 4K HDMI USB3.0 SD/TF Card Reader 100W PD, 7 in 1 Type C Adapter Compatible for MacBook Pro, USB C Laptops Nintendo, Type C Devices(Gray) https://www.amazon.com/dp/B099WTZGM...abc_R2F1P2X1274TN188EYAV?_encoding=UTF8&psc=1
Then you need to give the hub power and then plug the displaylink adapter and the HDMI from displaylink to your video out device
Open the displaylink app on your phone and then plug your phone in.
Give it a few seconds if it didn't detect replug the USB C hub.
It's a messy dangle of wires but it works

Question S21 Ultra Cable

What do you guys use? My already owned cables doesn't work on data transfer. Only charging. So I need a cable with data transfer capabilities and can fast charge my S21Ultra. What do you guys recommend?

Got my new phone yesterday and tried all my cables and dongles, but I could not get data transfer to work. Then I tried the short usb c to usb c cable that came with the new phone. It worked immediately.

I've had zero issues with these 6' Anker ones from Amazon. I've had them since the beginning of the year and use them daily.

I found with AUGM S21 Ultra update my data cables bar USB C to USB C cables stopped working. Prior to this update most USB A to USB C data cables worked.
