USB Host

Can anyone confirm that the Universal does not have USB host. Most places just say no but there isn't really any hard evidence of it. I know the processor supports it but did they put in the necessary circuitry for it? Whats strange is that the Universal's miniUSB port is the same as my Sharp Zaurus's miniUSB port and my USB host adapter fits in. Does not fit into normal miniUSB ports. Just the Zaurus which had USB host and the HTC Universal. Just seemed a bit odd to me. I tried it of course and did not do anything.
I'll experiment with this further and check that image of the mainboard closely.

everybody who posted about it in this forum reported it to not support host
connector means nothing all htc devices since the universal have had the same connector
heck these days they are talking about making it the std connector for all phones nokia and the likes too

This all hinges on the connector, and the hardware used to drive the connector. The Universal(and indedd, all mobile devices) use mini-USB connectors, which do NOT incorporate a host control circuit. This means that, since USB uses a protocol that might be termed as "Speak when spoken to", your device can answer the computer when it asks, it can NOT ask another device to speak to it.
To sum it up, you can't connect a pendrive to your PDA, but you can connect it to your computer, precisely because of the lack of the USB host controller unit.
Hope this cleared it up for you...
Cheers

This is not what I meant. I'm talking about a specific type of miniUSB connector.
And in the recent announcement to make a standard cell phone connector, they chose microUSB.
This is what I mean.

HTC Universal's miniUSB port.
A normal miniUSB port.
My miniUSB -> USB host adapter from my Sharp Zaurus fits into only the Zaurus and the HTC Universal. Doesn't do anything in the HTC Universal though.

Not possible.
If you check on the internals, you will find that there is no power output to the usb port in anyway. so, its a hardware limitation and there is no way it will support hosting, be rest assured!

host vs. peripherals
connectors mean nothing

I found a thread in the German PPCWelt.info forum where several people say that there MDA Pro supported USB host, with a special driver:
http://www.ppc-welt.info/community/showthread.php?t=74113&highlight=mda+pro+usb+host
I don't know how reliable this is (not every USB client can act as a USB host because of different hardware AND software), but perhaps you want to try it.
Alex
EDIT: They also say that your USB device needs a power supply because the MDA can't do that (external hub). Other people even say that without such a power supply your MDA could be damaged. This Engadget article is also mentioned:

I know that. I just wanted to know if the hardware was there for it thats all.

the hardware maybe there deep inside the cpu but the pcb lanes where maybe support chips were never connected rendering it absent

can some of german guys test it and report it to this thread.?>

Possible to use this adapter for usb-keyboard use on the note?

Is it possible to use this cheap 5-pin Micro-USB, type B - male to 4 pin USB typ A - female adapter to plug in a usb-keyboard to the note?
Or is it something special about these OTG-cables?
Please see the attached file.

I have tried a simple adaptor and it did not work - there are very similar looking adaptors that are OTG though.
Personally, I prefer to use a mini Bluetooth keyboard with integral "mouse" touchpad or an OTG cable to connect a similar USB keyboard rather than an OTG adaptor as I worry that I may lever the adaptor by catching it and cause damage by the straining the micro USB socket in the Note.
When you plug in an OTG adaptor or cable, the Note comes up with the message "USB connector connected" - a plain adaptor does not cause a message.
The picture below shows, from top to bottom, OTG USB adaptor connector, OTG USB adaptor lead, Wireless mini keyboard with mouse "touchpad", Bluetooth mini keyboard with mouse "touchpad".
Both mini keyboards came with wireless or bluetooth receivers which do not work with the Note as, I assume, they need "Windows" type drivers. The Wireless one cannot therefore be used with the Note (even though it also has a mini USB connection - probably only for charging use) whereas the Bluetooth one does work can as it connects using the inbuilt Android/Note bluetooth rather than using the supplied mini USB bluetooth receiver.
Hope this helps!

USB-OTG (they're all the same) works perfectly with some USB keyboards and mouses but not with all of them. I'm using Genius mouse and Microsoft Wired 200 keyboard.

Thanks, i'll try it. If it works it works
btw, neat bluetooth keyboard/mouse you got there!

I have a mini-wireless USB keyboard/trackpad from Kogan that looks closer to the mini-Bluetooth one in the 2nd post, and that works fine with my usb2Go adaptor and the Note. I know both look similar, but the button configuration under the trackpad on mine is the same as the Bluetooth one.
I like the idea of the bluetooth one mind you!
Regards,
Dave

Thanks for that info, very useful. I'm considering getting one, can you advise where you got yours (a link would be great, if not, a manufacturer name and/or part number would do ... worst case can you advise approx price & dimensions?)

Although I have a USB one I bought from Kogan, this thread made me aware that there were now bluetooth ones too, so I've just ordered this one from Ebay:
http://www.ebay.co.uk/itm/Rii-Mini-i6-Bluetooth-IR-Keyboard-Touchpad-2-1-UK-Latest-Version-2011-/250901297139?pt=UK_Computing_ComputerComponents_KeyboardsMice&hash=item3a6ae1f7f3#ht_2215wt_905
It seems to be a slightly later design/model than the one shown in the 2nd post here, but you can find that too if you search ebay with the term "mini bluetooth keyboard rii".
Regards,
Dave

looks good - the universal learning IR remote is a nice add-on too. Let us know how it performs when you get it ...
meantime, I see you've got a wireless USB k/b already working via USB OTG. I'm awaiting my OTG adaptor so I can try that out with my existing (compact, but not mini) wireless k/b with optical trackball. Not sure how much current the Note can supply for OTG usage but I guess I can just use a powered hub if required?

USB OTG Interface behavior VS USB Interface?

Hi, I am relatively new to digital 'prototyping' so USB protocols and almost everything digital is new to me.
The long and short of my question is, if I plugged a standard USB flash drive into an OTG adapter, and then plugged all that into a micro USB to standard USB (which I doubt actually exists) and plugged that combo into a PC, would I be able to access the flash drive? How exactly do OTG devices VS 'regular' USB devices work?
From the circuit schematics I've studied, it appears that the only difference between a standard USB and OTG interface is a bridge across pins 4 and 5. So how would this affect plugging said OTG device into a PC?

Yes. Long as your device supports it.

That is my $2 otg adapter...I plug in external HDD...flash drives ...keyboard... Mouse...PlayStation controller..
.tech you can make your own BC the pin config is only diff.

So if I directly hardmodded a standard USB flash drive with a micro USB plug, bridging pins 4 and 5 to make the device OTG-ready, if I plugged that now hardmodded flash drive into a micro USB (female) to USB A (male) the PC would still read the drive as a standard flash drive?
This makes sense because apparently on the micro-usb interface, pin 4 is "sense"?

Yes .

Thank you for your assistance.

Yes/no.
The standard (full-size) USB A and B connectors only have 4 contacts and 4 conductors.
The ID pin (#4) is only on USB mini and micro connectors.
You need to signal your cell phone to go into host mode.
That means that the connector plugged directly into the cell phone has to have a grounded pin #4.
Pin #4 is never carried over the cable.
In short, you need an OTG adapter plugged into your cell phone.
Modding other parts of the cable or the USB device you are using won't do anything.
You can (as I have done) take a razor to the connector that plugs into your cell phone,
take the connector apart and solder a wire from pin #4 to ground.

USB 2 and USB 3 cable is same speed

I just tested the USB 2.0 and 3.0 cable with a 800MB movie file, both cables are plugged into a USB 3.0 port on my computer so that everything is ceteris paribus.
The transfer speed to micro sd card with USB 3.0 cable was 1:51, the speed with USB 2.0 was 1:53.
The transfer speed to phone storage was both 0:25 for usb 2 and 3.
It makes virtually no difference if it USB 2 or 3 on the Note 3 in terms of speed.
What was is the point of having and using USB 3.0?

In your PC, open Device manager > USB root hub > Hardware Ids and check to make sure it is USB30

can you explain more, I don't understand.

And how did you connect the 2.0 cable into the phones 3.0 port ?
Are you even sure what you are saying ?
Either you don't have 3.0 on your computer or you didn't enable it in the phone.

just stick it in. usb 3 has two compartments where usb 2 can be sticked in. just google it.

Plug usb 3 in -> pull down notification center -> klick this usb notification -> u get a menu to select Mtp() Ptp() Usb3(x)

I only have mtp and ptp options.

You need to enable USB 3.0 when you plug it in a USB 3.0 port. It will appear if you are plugged in a 3.0 port. If not, you are just using 2.0 by default.

You are using the blue usb3 port on your pc/laptop? With the stock usb3 cable, all is working well in window 7 64bit for me. Just have to remember to select usb 3 on the phone when connected.

Hello Man,
let's first differentiate between two things ,1. Physical Cable 2. Configurations
1. Physical cabling : In USB3.0 case you should be using the white cable that comes with the mobile and use a USB3.0 port in the laptop/PC usually the USB3.0 port in laptops has a "thunder like logo" beside it or something to differentiate it from normal USB2.0 ports , in USB2.0 case u can use any micro USB cable and plug it in any PC port.
2. Configuration : in USB3.0 case ,once you plug the cable in the USB3.0 port you shall find USB option in the notification panel in your mobile ,tick it to enable the full speed port.
In USB2.0 case you will not find this USB3.0 option in the notification panel.
I hope this helps...

On some PC, the USB3.0 logo is as below (SS = SuperSpeed):
To make sure the USB port on your PC is 3.0, open Device Manager > USB Root Hub > Properties > Details > Hardware Ids and make sure the Value = USB\ROOT_HUB30

Galaxy Tab A 10.1 usb connection quit working

I've had a Galaxy Tab A 10.1 for over a year now and get the most use out of it by connecting a thumb drive via the usb connection (for viewing pdf files). It's worked great until a few days ago.
After connecting as usual there appeared a message at the bottom "something something disconnected" (the "something something" being I don't remember exactly what and the message disappeared before I could see) and now the usb/connection doesn't show up in the "My Files" window (just the "internal storage" and "sd" indicators, whereas before I got the additional thumb drive designation).
I've tried two different utg connectors, no good. I've checked the thumb drive in my pc, it's fine. I've tried connecting the tablet to my pc via the usb, it doesn't show up at all. I can still move files between my pc and the tablet via wifi but I want my usb connectivity back!! I suspect the connection the utg plugs into.
Also, (I'm not sure if this is a separate issue or related) battery recharge seems to take much longer ... is this a sign of the tablet getting old? I could understand if it was 3 years+ but 1 year??!!
Thanks for any help or ideas as how to fix this!

I'm assuming you are using an OTG cable to USB Drive or a micro USB drive right? In other words the part you plug into you Tab is a micro USB and not Type-C USB? If it is micro USB and not Type-C try this ... https://www.youtube.com/watch?v=sGGdsMsK3VU. If it doesn't work the pins inside are probably damage and you need to replace the OTG cable or the drive, what ever you are using. If Type-C USB same thing. Needs replacing. Those pins ware out over time and use. Thats my best guess with out pics and further information.
Edit: Found this Image of what damaged micro USB pins look like, the damaged ones being on the right...

Yes, I'm using a usb (to take the thumb drive) to micro usb connector. I suspect it's not a connector issue as I tried three separate connectors and none showed a connection to the tablet (i.e. the thumb drive did not show in the "My Files" page as it used to) ... all the pins on all 3 connectors look good, the fit into the tablet port is tight, no looseness. I've looked closer at the micro usb port on the tablet and I'm beginning to suspect that's the issue as a receiving contact on the outer edge seems to be damaged (possibly) ..
Thanks for the reply and the link to the Youtube video!

No Problem, I've never had a female Micro USB port go bad on me , but have heard of it happening. A good tug in the wrong direction I suppose could pull the solder connections apart or maybe even damage the innards. Is the Tablet taking a charge? I'm a little confused to actuality what part your referring too. Here is an image explaining what the different types of USB's I think you are using. Tell me what color circle you think is damaged. Or if you are using something else entirely different.
