USB hub problem - MTCB Android Head Units General

I'm considering to add a powered hub to my Hui because i want to connect a usb flash drive, a dab dongle, a hard disk and maybe a wifi dongle and i want to charge my cellphone.
Right now i have an unpowered USB hub connected to my usb storage port 1. When i connect 2 usb sticks to the hub only one is detected in android, when i also connect my dab dongle, my dongle works. When i remove the USB sitck which is not working and i plug it in my USB 2 storage its also not found ( in root explorer a white icon appears before the name "usb_storage2").
Can some one explain me why the USB storage devices are not mounted / found in android? Is it even possible to add more than 2 storage devices or USB devices to our Hui? Or do i have to mount a third USB storage device manually?? Or is it because o the less of power??

I don't think android currently supports more then one USB data device. I know there are workarounds but I have not tried any. Most of these devices come with at least one sd slot so I think most (myself included) just live with the one usb limit.

SDIO USB Host

hi i was wondering if anyone out there new if there was an SDIO USB HOST card, similar to the shown on the link below (but obviously SD not CF)
http://www.ratocsystems.com/english/products/subpages/cfu1u.html
if not, does anyone know/have tried the above CF to USB Host with a standard usb webcam and got it to work? if so can you explain how i go about setting it up.
thanks

i'd suspect that the fact that usb to host have to supply 5volt with 0.5mA
it could be an issue for something as thin as an sdcard
also not sure if the sdio interface even operate at 5v
usb host
I haven't seen an sdio to usb card, but I use my "htc universal" with it's mini usb as a usb 1.1 host. It works ok but you have to supply external power.
if you have that working you are the first and only person i know of who gotten any htc device act as usb host
sure there were rumors that it would do host
but later on ppl retracted those claims
After wiring up a cable for that, how do you set the phone to 'host mode'?
Thanks
usb host is not a mode
your pc is in host mode always
as are the 2 htc devices which do support
usb host out of the box
is a device is connected and the driver
is present the device works
Nope, USB host is a mode. It's the whole Master / Slave affair. Granted, it's automatic for most devices when another is connected... ah... that ought to answer my question I guess.

HTC Advantage 4 - 1 Cable, Not Working??

Hiya,
I just got my cable from expansys, the vga and s-video out is working fine, but i haven't got any thing usb to work yet. I've tried flash Drives and a card reader, just no response, no light or any thing... is there a trick to it or is it not very compatable or is there a chance mine is faulty?
cheers
My guess is that although it is a Host, it does not supply any power, I say this because the battery is only 3.7 V DC and USB devices are 5 V DC, this means that there is not enough Volts in the advantage to power a USB device to start with, never mind powering a USB device and an Advantage at the same time.
You will probably need to plug it into a USB hub that supplies it's own power, like this one
http://cgi.ebay.co.uk/USB-2-0-4-Por...106823769QQcategoryZ96866QQrdZ1QQcmdZViewItem
I had the same problem but it was because the TV out was still on. Once I turned this off in the settings menu it worked fine.
I too had no trouble hooking up a flash drive. No other peripherals were attached to the cable. Alas, no go on a hard-drive MP3 player, but trying a powered hub is a good idea.
Have you tried connecting your USB device, and then soft resetting?
Works for me.
I have no detection of USB devices by my Advantage.
I tried with and withour Soft Reset before and after the cable connection, before and after the cable and flash drive connection, with or without the VGA or Video Output disabled or enabled, but my Advantage does not recognize any USB device (I tried with 2 flash drive, a keyborad and an optical mouse. Nothing to do. These devices do not work with my Advantage).
It seems that the relative drivers are missing.
Someone has a sure fix or solution to this problem ??
Thanks
Battery Powered USB Hub...
This device should work well with the x7500/Advantage. It doesn't require you to carry around a bulky power plug. It runs off of 4 AAA batteries and provides power for up to 4 USB devices. Since the x7500/Advantage has limited power and can't power external drives itself, this is a nice addition and cheap. Hope someone finds it useful.

I have the Dopod U1000. I have connected a thumb drive and a USB mouse without issue. The mouse is useless as far as I can tell as there is no pointer though the buttons work.
I have no problems with a T-Mobile Ameo and a 1Gb Corsair USB Flashdrive - don't even need a soft reset. It's listed as 'Hard Disk' on the Ameo.
Question though: can I just unplug it when done? I'm used to 'safely removing hardware' on the PC, and it just feels wrong unplugging it from the Ameo, but I can't see any similar 'safely remove' method.
Hi.
It depends of the usb device. My 1GB pen drive is recognized but my 4GB isnt recognized (my 160 GB isnt). So I suppose If the usb device isnt powered then only "very low powered" devices are recognized...
If I connect my 160 GB and I plug it to AC then It is recognized correctly...
Does mini usb-usb host cable exist? Where to buy it?
THX!
Look this one http://www.pixmania-pro.it/it/it/255677/art/cowon-iaudio/cavo-usb-host.html#
seems to be what I'm looking for...don't you?

Search the forum for the Modaco Mouse driver. It has a mouse pointer and works flawlessly with a USB Mouse!

Hi,
I have the HTC 4 in 1 cable for the T-Mobile Ameo (HTC Advantage 7500) and the ability to access a USB thumbdrive or stick appears to depend on the device.
The following devices worked without a hitch:
- Kingston DataTraveler 1GB
- Q motion 1 GB
- SanDisk MobileMate SD+ (This a SD card reader in a USB stick format, very handy to copy data from a SD/miniSD/microSD card to your 7500 without going through Activesync)
Another noname USB stick that I had did not work.
So the trick is to find a low powered USB stick.
Cheers,
Tim
Please can someone give me some exaples about how could I use
Video/S-Video/ option in 4 in 1 cable, considering that I can image how to properly use VGA out and USB host?
THX so much!
Hi,
before I buy it, could it work?
USB 2.0 (compatible 1.x)
Adapter USB from Type A (female) to mini USB 5pin (male)
THX so much!

Yes, that should work for you. I'm sure it's not more than $5.00 USD. ;-)

Are you hoping to connect USB accessories to your Athena with this?
If so, it will not work.
Only the 4 in 1 Host cable connected to the ext USB socket will do that.
This adaptor will only connect to the Sync & Charge socket, and will not provide USB Host capabilities.

So it will not provide me host function...?
Than the HTC cable should have something like a "chip" in it to provide host, is it right?
Yes, the USB Host chip must be either in the addon cable, or linked to the extUSB socket in the Athena. But definitely not the sync & charge socket.

OTA ICS: USB Disk mount?

when looking at the storage control panel, it lists internal, sdcard-ext, and then "/mnt/usbdisk_1.1.1" and says "insert an [sic] USB disk for mounting".
so if i were to come up with some sort of adapter, could i plug a thumb drive into my phone's micro usb port to move files between the phone and the thumb drive? i can think of plenty of times that would be useful!
Tried. OTG cable works with Samsung galaxy S2 devices (Skyrocket using either SKY ICS or rooted OTA) but haven't got it to work on our Droids...(Bionic ICS leak, RAZR ICS OTA, Droid 4 ICS OTA...all rooted).
But if someone can prove me wrong I'd be happy to "eat my words" ...

OTG works, BUT only in a very cumbersome way, since external power is needed.
A powered USB hub does not suffice, since it only powers the slave devices, not the host (= phone). The phone must be in charge-mode, which requires a Y-cable.
You need:
- an OTG adapter
- a USB hub with mini-USB in
- a USB Y cable with 2 normal USB plugs and one mini-USB out
Then
1. Connect the OTG adapter to your phone's micro-USB input
2. Connect the 'middle' USB plug of the USB Y cable into the OTG adapter
3. Connect the 'outer' USB plug of the USB Y cable to a charger (can be a portable battery as well)
4. Connect the mini-USB plug of the USB Y cable to the hub output
5. Connect any device you want to use to the USB hub
It looks like this (found this picture for Razr):
http://www.flickr.com/photos/teppan_hakushaku/6817735705/
Edit: I verified it for Droid 4 last week, but didn't take my own picture yet. Works with ICS .215 leak, no 3rd party apps (like 'StickMount') seem to be needed.
Edit2: According to some other posts in this forums (search for 'OTG') it will only work for FAT32 formatted drives. Didn't check this in detail but my drive was already FAT32. Also I found it did not work for my cheap wireless keyboard's USB dongle, but connecting a wired keyboard worked fine.
...reminded again why I love this community...
...no possible links to a purchase of this "y" cable?
Be strong and very Koragus, my ninja...
Glad I could help!
They come with some portable harddisks, so that's where I got mine. Not sure about the linking policy on XDA, please remove if not allowed. Here's an example:

[Q] USB Audio (car usb connector)

I've been searching for a while to solve this.
I'd like to connect my HTC one to my car usb connector.
I've seen several repoirts claiming usb audio works, connecting dac's etcetra.
I know I can connect usb drives with a micro-usb to usb connector, tried it and this works.
But I have also seen people saying you need an USB OTG cable for this, so what is it?
I've already connected my One via the micros-usb to usb cable to my car but I do net get audio via the usb on my car equipment.
So again the question, is audio out available on the htc one (and on other android phones) with the stock rom.
Some of the report where talking about CM roms, I do use the elegancia one but I have no intent of switching to CM.

since the HTC One does not automaticly plug as mass storage i guess that the car radio simply does not recognize the phone as a mass storage with music.. an USB OTG cable would "fix" it since it will force the phone to be shown as mass storage.. (its a guessing anyway)
And you have guessed correctly. The USB otg cable works fine.....except it added ringtones et al when you select root folder. Worked ok if I navigated to the music folder (assuming your vehicle has that option).

Well, for me it does not work.
As I said before I can attach a USB drive to my phone and I can accomplish this by using a micro-usb to usb adapter.
When attaching the drive my phone complains it cannot charge and that I need the standard charger.
But when using a file explorer I can see (read and write) the contents of my usb drive in the storage/usb folder.
I thought this was enough to decide that the converter was OTG but now I'm not so certain about this anymore.
Is every usb to micro usb an OTG or what are the extra requirements?
Anyway I tried again to connect to my car audio and the message I got on the car was
that he could not charge the phone but the phone was as well not recognized as media input.
Because OTG adapters are very cheap I ordered one which explicitly says it is OTG,
I'll see what happens when I can try that one out but in the meantime all comments are welcome.

Yes, the cable I had explicitly said "OTG".
I only experimented with this for fun, my Elantra also supports built in bluetooth (phone controls are on the steering wheel, mic in the roof) so I mainly put my One in my car kit, launch car mode and away I go.
The OTG cable worked well for me when I tried it though. It did NOT work with my Son's Nexus 4 so these things can be finicky.

Galaxy Note 5 USB OTG Doesn't work at all

Hello, i've bought a galaxy note 5 a week ago. N920C, international version, Marshmallow 6.0.1, not rooted. I was able to get a 32gb variant only, i though that's not a problem, i will increase my storage via USB OTG with Micro SD card reader or USB Flash stick! Today i received all the parts, i've spent whole day trying to find out why it doesn't work, i've downloaded many apps to check OTG compatibility and driver condition. My device recognises the connection when i put in USB OTG cable only - when the screen is off, i connect OTG, screen lights up. Also throubleshooting apps say the same, the device knows when OTG is connected.
The occuring problem : when my phone is connected with OTG cable, i also connect my USB Flash stick / SD card reader / mouse / keyboard / another usb flash stick --> Nothing appears on the screen, file managers show nothing and the troubleshooter stops at recognised OTG cable. Other connection tests won't pass any further. Troubleshooter conclusion - "System NOT Detect USB OTG Signal"; (App name: USB OTG Checker).
After buying a decent high-end device i expect it to have availability to expand storage space via USB OTG, although it was written in phone's specification list. 90% of note 5 devices on the internet say it is working perfectly and i would like to get mine going too :|
