Hi,
I have a USB GPS receiver that is powered via the USB cable wired into my car which I occasionally use with my laptop.
I would like to connect this to my universal, but am worried about it draining the battery.
I have a small Belkin USB hub that has external power (which I can provide from a transformer in the Cig lighter socket) that has one mini USB socket which is usually used to connect to the PC and then 4 standard USB ports.
If I connect the GPS to one of the USB ports and then Universal to another they should both be powered, but will the Universal be able to 'see' the GPS?
I know I could go and just try it, however it would be useful to know before hand incase it doesn't work when it is supposed to due to some driver issues or something similar.
Any thoughts appreciated.
To My understanding this is not possible, the mini usb port on the uni is not capable....there is a word to describe it but cant remember at the moment. The port can onl charge and sync.
it won't work
Sadly this won't work as the uni does not support usb host - it can charge and sync but thats all as far as i'm aware.
that was it "usb host" :lol:
THanks. That's a shame, I'll have to get a BT one now.
Or look for a cradle that will act as the host for both devices. Sadly when I searched on google, most of the returned results are blocked by my work firewall, so I can't see for sure that one exists for recievers with usb plugs.
edit* Although thinking about it, the price of a cradle could well equal a new bluetooth receiver, and bluetooth would be vastly more practical use of your cash.
Thanks, already trying to track down a BT receiver.
Why not?
What makes me wonder is that when my MDA Pro is connected via activesync with my PC, I can browse with my MDA over my PC-Internet connection into the Internet. Why should it not be possible to use the usb connection of the MDA with other hardware? :roll: Isn't it just a driver problem?
Any ideas???
hm
My thought on that would be that your MDA is acting as the slave device when attatched to your PC, not the host.
Hey, here's a market opportunity for you USB GPS manufacturers - add USB Host capability and TCP/IP protocol to your USB GPS device... What? Can't hear you. Ah, Too expensive?. Ah, ok :-(
Hey guys!
I've searched and searched for something to allow me to transfer data via a serial cable from my phone to device.
Let me try to explain this.
HTC Wizard
Windows Mobile 6 (Explore 1.1)
I have style tap (palm os emulator)
Software for palm os for a stand alone fuel managment system (msefi.com)
So on my car, I use a serial cable to program and get realtime data.
Now I know they make bluetooth to serial adapters for around 70, but I was wondering if they make a mini usb to serial cable for the Mobile OS.
Anyone have any ideas?
Thanks
Chris
Well, you could theoretically get a USB to serial adapter that has a cable. Then cut the USB connector that goes to the PC off the cable and just splice the miniusb plug onto the end. I don't know about device support though I'm going to guess you would have to at least come up with a driver and the device might not support that type of functionality at all anyways.
Since the Wizard doesn't have a USB Host (aka USB OTG) the short answer is no. Even more importantly, the wizard won't power the serial adapter so the device is a dud to begin with.
The odds that the BT to RS232 connector method will work are far greater than the USB method.
I connect the mouse to HD2 with a USB hub(afford power supply to USB Device),but it did not work.
Do I have to first connect the cable and then run the Ubuntu?
Is it reqeuired that the USB hub must also afford power supply to HD2?
Excuse for my bad English
Do any one know that?
er... Is there any one know that
I have the same problem, im sure its all wired up correctly, I get lights on the devices but they do not work
I have an andrid. Stick mx2 imito and I have a powered USB hub but I can't configure how I am meant to to get it to read from the hub. I have 2 ports on the stick, one full sized usb and one mini usb .
And In terms of devices I have my keyboard I want to add
1 external usb hard drive
And if I can get it to work a USB wifi dongle
Huh!
Since there is only one full sized USB port, I would think that is the solution. That's how it runs on mine anyway. Connect all your devices to the powered hub. Should be straight forward
So I would need a usb cable male to make? To connect to the hub. Do they exist ? I will try find the cable .
i cantget it to work
so the large usb port. i need a cable from that to connect to the hub? usb port
but i dont have a usb port with the same end? male to male etc
Get a USB powered hib

The hub will come with one male USB to connect to the stick.

Make sure to get a powered hub so that all the devices can be supported properly.

this was an old hub i had, i dont have that wire. its a mini usb to full usb type connection isn't it?
Plenty of such options available
Here is another on ebay. Just search for powered USB hub and choose one

ok great, so the port next to the power socket, is the cable i need to attach to and from the imito android stick? so that will be the main one and any other usb devices can go on the hub.
m confused on where i need to connect from on the android stick. which has 1 full sized usb, 1 mini usb otg socket and 1 mini usb (power)
It should also be possible to modify a USB hub to back feed power to the HDMI stick.
You would then power the hub with a sufficiently large USB power supply to power both the stick and all of the USB devices. In most cases, a single 2.1 Amp USB "wall wart" would work to power everything, unless you are really running something outrageous.
My NX003 (Same as MX1) can be powered from either the dedicated USB power jack, or the MicroUSB (OTG) connector.
So to build something like this, here is what I would do:
1. Obtain a USB hub I was willing to modify (destroy, as far as any other use is concerned)
2. Disassemble it.
3. Remove the input (Host) cable or connector.
4. Attach a short cable with a MicroUSB plug. Connect all 4 wires correctly.
5. Find "The diode" - Buy "The diode" I mean the one that that allows USB power to flow from the host to the peripherals when used in non-powered mode, but prevents power from flowing upstream to the host when an external power supply is used. (see referenced link).
6. Remove this diode, and replace it with a wire, jumper, or solder bridge.
7. Ensure all power circuity in the hub can handle 2 amps. Add solder to traces, or add jumper wire if needed to beef up current capability.
8. Reassemble, and clearly mark so that this hub is never used with anything else.
If the HDMI stick were powered via a coaxial connection, but is still powered by 5 Volts, I'd add a lead and coaxial plug off of the +5 in the hub. you'll have 2 wires, but it will still work. (Watch polarity.)
I have done this successfully for a prior, similar project. Reference Here: (Scroll to section about power.)

So why don't I actually do this to power my NX003? I did it an easier way. I bought a Tronsmart Prometheus. It has 3 full USB ports built-in.

Thank you for the informatiom, but its a bit too technical for what i want... but i appreciate you efforts in writing this.
my stick can also power via both usb ports (mini) i have connected the cable from the stick to the hub which has been powered to the mains and it works, but the problem i have is when i put another usb device in the hub, it doesnt detect it e.g. keyboard wireless and i don't think the device has enough power to run my usb 2.0 portable harddrive (not main powered) - how can i get this to work? i have tried connecting this directly to the stick, but it just makes a beep sound. im guessing its lack of power... and i was hoping a hub would help.
my hub is powered 3.5 or 4 watts i believe...
Strange
Wakkaday,
This is very strange. On my MK802III I connect the powered USB hub (4 ports) to the full USB port.
I connect my bluetooth keyboard, 1 TB HDD and USB ethernet to the hub.
I power my Android stick using the 4rth port in the USB hub.
If I want USB audio, I replace the Ethernet/HDD with a USB audio peripheral.
All my peripherals work right out of the box. The only thing I am considering now is to have a separate power supply to the Android stick so that I can use all 4 ports on my hub.
It seems your device is not supporting the peripherals? Are the working when you connect directly?

I'm also trying to use a powered 4 port usb hub with my android stick, but it doesnot recognises the hub. Do i need to have any usb host drivers or change any setting to get it work? My stick is on Android ICS.. Thanks in advance
Hello all,
I'm currently attempting to have my Nexus 7 be both connected to the internet via a USB to ethernet lead while also being charged.
I'm able to do each of these individually but when I attempt to use a random USB hub i have to hand I am unable to get both to work, the charging works but the ethernet does not.
When I connect straight through (OTG Cable to USB to ethernet converter) it works fine, however, when going through the USB Hub (with the power for charging disconnected) comms is achieved (ethernet switch is flashing) but I can't connect to the internet. This leads me to believe there is something specific I require for the USB hub.
Do I require the USB hub to be something special to enable this/ is this scenario even possible for me to achieve?
Cheers for the help.
