Ok,
I was reading a post over at the PSP Linux forum about suspicions that the PSP has USB On-The-Go abilities. USB On-The-Go basically means a device can be a USB Host or a USB Client, and is usually restricted to a a certain class of USB devices - eg you might want a USB OTG camera to only act as a host with Storage Devices.
Now to quote this page http://www.beyondlogic.org/usb/otghost.htm ...
As a device can be either a host (A-device) or peripheral (B-device) and that the USB specification calls for different types of connectors for upstream and downstream ports, the OTG spec introduced two additional connectors. One such connector is a mini A/B connector allowing a mini A or mini B connector to plug into the one recepticle. A dual-role device is required to be able to detect whether a Mini-A or Mini-B plug is inserted by determining if the ID pin (an extra pin introduced by OTG) is connected to ground.
This basically says that tradictional USB uses A connectors for Hosts and B connectors for Clients. Because they needed to allow OTG devices to be used as both a Host and a Client, they designed a port that could accept both mini A and mini B connectors. Unsuprisingly, this is called a mini AB connector
So, for small USB Client devices, a mini B connector is used. They look like this:
http://www.cypressindustries.com/products/images/ccmusbb-32005-201.gif
For small USB OTG devices, the new miniAB port is used. They look like this:
http://www.cypressindustries.com/products/images/ccmusbab-32005-700.gif
so go look on the bottom of the Magician. Low and behold, a mini AB connector! In fact you'll see the cable they gave you with your magician is a mini B but it still fits into the mini AB connector on the jam, even though it's a slightly different shape.
Now, it could be USB Host was planned or the port was added to allow backwards compatability with the Magician2 or whatever, but all the same it's a pretty interesting feature, given that a company can probably source mini B connectors for cheaper than mini AB, (as not many companies are making them yet).
So... does the Jam have USB host functionality or not???
If so, here's some drivers to take advantage of this function. Use at your own risk.

http://www.anypakusa.com/PPC/
Maybe one could connect the jam to a hard drive???
I've did some research, and if the Magician supports USB On The Go (why else would there be a MiniAB connector on the bottom of the device in stead of a normal MiniB (4p) connector) it should be able to play USB Host.
I'm ordering a MiniA to A Female connector and I'm hoping it will work out so I can connect a USB Flashdrive, GPS reciever etc.etc.
Why do people need USB host on their Magician? I can only imagine using an USB keyboard, but everything else I can do with bluetooth and my 4 GB MMC card.
And for using my Magician as "USB-Brick" I use this here:
http://www.softick.com/pocket-pc/cardexport2/
Well... I don't like wireless That's the most important reason.
I want to use a wired GPS-reciever in my car.
I want to be able to connect a USB mass storage driver.
And I'm a geek who just wants to explore every possible option
So why shouldn't I give it a try

Well, I think most of the people are interested on the fact that you can actually use an ext hdd, e.g. you have 80GB+ of videos, mp3s that you play on your unit (although I doubt it is able to power the 2.5" type). You can print documents from your unit to a printer, get your pictures off your dig camera, use a USB ext wifi, etc.

Excuse me for being a pain, but all these options are nonsense IMO, because Magician is the ultra portable device.
What is the sense of attaching a bulky 80GB hdd and cables to the Magician? To have its batteries empty in only 15 minutes?
Printing can be done wireless via infrared (HP printers) or WLAN, digicam pictures I can load by directly inserting its card in Magician. USB Wifi is also a joke as it drains the battery immediately.
If you want all these options, do it right and buy a Subnotebook and a 3G UMTS PC-Card.

I really doubt it supports USB Host. The board definately supports it, but HTC don't implement it. I think this will yield no results....
Hope you prove me wrong
And dude...... 1.8" Hard Disk Drives are TINY!!! so just quit being a spoil sport
Of course I wouldn't be connecting an periperal eventhough how small it is while walking around, but while at home or in the car sounds ok.
Well USB OTG would be great as I could dump all of my pictures on my digital camera (1GB card) onto my Charmers 4GB SD card. On holiday and stuff this would be really handy so I don't run out of space.
to be honest its not about what you can do with it, its partly bragging rights, hey look i can do so and so on my phone.... etc..
I, for one, would like to see a USB host hack.
Yes, there are SDIO wifis.
Yes, there are SDIO cards that allow wall projector connection.
But these require that I give up my memory card, where I store my stuff, making these things have only limited use.*
I could use Bluetooth, but:
- A standalone BT <-> Wifi bridge that isn't a PC or doesn't connect to a PC does not yet exist. There is a Bluetooth portable GPS receiver, but that's it.
- Projectors with BT enabled are FREAKING EXPENSIVE. Not to mention they aren't common. I've always wondered what that stray miniusb port on the more common small business models are for...
So why not buy a laptop, you ask?
Well, I already have a PC.
If you're suggesting I buy one, either you have never carried one around before, or you're so rich you can buy the lightest, least bulky ones without burning a hole in your pocket.
*That Sandisk 256/Wifi can't quite contain everything I'd want on my 1gig, leaving my only recourse to be (hopefully) the Eye-Film which is currently only in prototype stage. Sandisk already EOL'd that product anyway.
There are only 2 possibilities to get USB Host:
1. Wait for the WM2005 ROM for Magician, maybe HTC implemented the USB Host driver with it ;-)
2. Wait for HTC Trinity, maybe it has USB Host.
However, both options are not very realistic, because a WLAN USB Stick pulls 500 mA from the battery, so you get about 30 minutes battery life...
An USB Host has to provide power to the connected devices, and this is the reason why we probably won't ever see it on a mass market device.
You think you connect any USB device on that Host and it works? Like printers, scanners etc? Sorry, but you're dreaming. You need drivers for this and they just don't exist. There are no USB GPS mice that work with Pocket PCs and there are no Wifi sticks that work with Pocket PCs, period.
The only thing you could do is connect some mass storage device and use this. Besides that I'm 100% sure that the Magician doesn't support USB Host functionality, period.
So get a new PPC with Wifi and use Wifi disks etc. USB host would be nice but no Phone Edition device that I know of has it.
It would be SOOOOOO nice to connect a harddisk to my magician. A 4GB SD Card cannot store all my MP3s. And I want them all in my Car.

Certain drivers do exist; like the JetCet unofficial ones. You'd also need to load drivers for SD-IO cards as well (IIRC the Sandisk Wifi/Mem combo needed a driver), so drivers are actually a non-issue. What matters is that it can be done.

Magician also supports USB host, because
your BT is attached there. So what? It is the 500mA
current source and the electrical connection to
the USB socket that counts.
Currents not a problem i should think. All USB devices are standard 0.5A supply.. and all USB devices use the same supply.
Hi,
I'm looking to buy a Universal but I've a question on the USB port.
Has anyone tried connecting a USB hard drive directly to the Universal? I have a Archive Gmini 220 and I was wondering if the Universal would see it as an external drive and if this is the case can it run media on the drive such as MP3 or AVI files? Also has anyone tried connecting a card reader to read CF or Memory sticks etc.
Any rumours of a Universal with internal hard drive?
Captaink
Olnly thing i've heard is it does support but peoples who already tried says nevr made it work.
That's because just as with a normal PC it needs drivers to work with your device.
It's just a matter of time........ :lol:

Agreed. This picture

Having a USB socket doesnt mean its a USB host!!!
It has to have that mini usb socket so that you can sync and charge, as they dropped the old style 21pin connector now. Its just like the Magician with usb only now.
There have been rumours it supports USB host mode, but ive not heard any confirmation or proof.
in this review of the device they say it does host

The PXA270 has a builtin USB host and
can operate as an OTG device. The guys
at HTC must be really sick if they have
not wired it.
I don't get only one thing: what USB 2.0
means here ? OTG ?
in which case it seems that HP and DELL are sick aswell

I bought a USB female to female adapter to plug on the end of the charging cord, some things work, some things don't.
List of devices that work:
HTC Hero - Mass Storage mode (works 2 out of 5 tries aprox.)
Logitech G9 - Works, although only default buttons (left, right, scroll, middle) seem to work
SanDisk Cruzer 4GB USB Stick - Works
Generic Logitech wired keyboard - Works, although not all keys do.
List of devices that DON'T work:
Logitech Wireless Keyboard K250
USB external DAC
Generic Logitech USB mouse
I hope it can read usb flash drive too !!! already bought my female-to-female adapter too
I just tried hooking up my HTC hero with mass storage enabled and it seems to be hit and miss? It recognizes it 2 out of 5 times or so.
How about finding and wiring USB from the 40 pin connector
It is a given the 40 pin connector has USB. Does anyone have pinout / mating connector info?

Don't have any on hand at the moment, I will possibly have access to an ext HDD tomorrow though and will check it then if I can.
That's great news. I did like having USB host on my GTab.

i will have to try again, i built a gender changer, tried it with one mouse, and it did not work so i assumed it would not work for anything, i'll have to try some thumb drives or something.

it seems really picky, it recognized my G9 mouse but not a generic logitech one.
Just speculating, but I would guess that it isn't up to spec. So devices that have looser requirements will work (say it can take 4V instead of requiring 5V), but devices with stricter requirements fail.
did you try a all-in-one type card reader?
or connect digital camera to it?

No, Usb mouse is supported by HC. You can use one with the dock. This is more likely a power thing. The port's main use is power in and data, not power out. It may have strange limits.

Picked up a USB female to female plug today, and proceeded to plug in various drives, mice, Phoness etc, but no sign of anything happening at all. Is there something else I'm missing here? Cheers.
Can anyone with an SD/card reader see if it's recognized?
I'm going on vacation soon and would love to back up my photos to the TF.
Thought about this 2 days ago and bought one yesterday. Tried to plug in my Inspire 4G, external USB HDD and USB jumpdrive. None of them worked.

I tried a multi card reader and it didn't work. I didn't try a card reader that reads only SD (don't have one) but I doubt that it's gonna work given everything else I tried didn't (usb mouse, usb flash drives, Nikon DSLR)
Ok, in theory Galaxy S 2 supports USB On-The-Go which means, it can be a USB host device for things like pendrives, digital cameras etc.
Granted of course, that you have the necessary cable.
Has anyone tried this feature?
Also, does the connected device have to be formatted as fat32?

FYI, mouse and keyboard are bluetooth.
I agree with the reviewer, big black mark on Samsung for not including the required cables with the phone for USB and HDMI.
at about minut 4 he says that usb mouse and keyboard doesn't work.
this is really a bad news for me

I am also afraid so When my phone arrives, I'll test it with ntfs & ext3.
Update on USB Mouse - some are working. Check my thread in the accessories forum for more details.
Hi there,
Got my £2 cable from Hong Kong (ebay purchase today).
Works great - even runs my 500GB HDD (this has to be plugged in to operate anyway - not sure USB powered HDDs will work).
If anyone's interested, the item description was:
Micro USB Host Cable for Nokia N810 OTG on the go N 810
No mention of the SGS2 - but I can verify that these work just fine!!!
Jamie
Any Nokia compatible OTG cable seem to work. I've successfully tested several different cables (all from eBay) with usb sticks, optical mouse and usb based memory card reader. However, usb based wifi sticks, fast ethernet dongle and tv-card didn't work. We probably need some new drivers and possibly more power (an usb hub could fix this).
I bought the Nokia USB OTG adapter too. With FAT32 Sticks ists working. But without NTFS support it is nearly useless for me.
umm...i have a nokia n8 and i took off the OTG cable that came with it before selling it in favor of buying a new Galaxy S 2.
However, the nokia OTG cable is perfectly rectangular, whereas the Galaxy S 2 cable connector is a bit "broken off" two edges, hence, using them is impossible together...but i managed to get them to work (in the shop where i tried the Galaxy S 2 at least, i didn't buy the phone yet).
I used a rasp, and filed off the edges of the Nokia OTG cable carefully to match the "broken edges" as the Galaxy S2's connector shape...took that cable to the shop where there is a working Galaxy S 2 unit, and connected it with a flash disk on the other side aaaaaaaaaaaaaaaaaaand......it worked !
If you have the caution and a rasp, i think Nokia's OTG cable should work too..they're cheap off ebay too, aren't they ?
Just ordered one of those off ebay (The Nokia N8 compatible one). Would receive it by tomorrow. I hope it works!
Here is mine ****ty review of USB mouse, USB keyboard and USB lamp.

here's mine, got it also from ebay.
If you can't get it to recognize USB mass storage I would suggest using USB Mass Storage Watcher: https://market.android.com/details?id=com.skidmrk.umswatcherotg. It will let you mount any type of external storage (NTFS, FAT 32/16, EXT, etc... It's free.
Also, this is a good USB host cable: http://www.amazon.com/gp/product/B005GGBYJ4?ie=UTF8&seller=A76FR6O1NBAXV&sn=T & S Electronics, LLC
I seem to get a "Clear USB" error when I plug in certain usb drives. I'm not sure if this is related to the drive being NTFS or if it is above a certain size. I can't for the life of me find any specs on the whole feature, including its maximum output power.
Could anyone shed some light on the subject from their trial and errors?
Thanks,
Alex
It works with a lot, but not all USB devices.
It doesn't read NTFS format.

Hi,
Is it possible to mount an 2.5" HDD without an external power source?
I would like to buy an Western Digital HD Elements SE 1TB 2.5 USB 3.0 but I do not know whether it is working with my Nexus 7 or not...
A usb stick (with an usb OTG) is working but a real hdd needs a lot more power.
And a self powered hdd (with wifi) is not an solution for me.
Thanks in advance!

It depends. I had to splice 5 volts of power into the usb cable of my older usb 2.0 ext hdd to get it to spin up and mount, but some others I know say they dont need ext power on their newer usb 3.0 ext hdds. But, I dont know if it is all usb 3.0 drives.

Let's say, I buy a 2.5" hdd without external power source but I have no luck and it can't be mounted (not enough power). Is it possible to somehow plugin an external power source, so the hdd can spin up and mount?

That means, a usb OTG is wokring fine with usb 3.0? Usb 3.0 is compatible with usb 2.0, but I was a bit concerned that the usb 3.0 to usb 2.0 to micro usb 2.0 combination may cause problems.
I know I'm reviving a thread a bit here, but I have a WD Elements USB3 1TB drive and an OTG cable.
When I first got the drive and cable, it all mounted and worked great. It wasn't until I hooked it up to a PC for the first time to transfer stuff to it that I started getting issues.
Now, I can use it with the PC no worries, but it won't mount on my N7. It'll sometimes flash up that there's something, but then nothing. Is the format wrong? Should I go with making it ext4 rather than NTFS?
Been hunting for more info on it, and will continue to do so, just hoping that someone else has come across this and has a fix or some idea on what's going on.
Thanks
My guess: The Nexus 7 has not enough power to spin up and mount the drive. You have to use an powered hub (e.g. Y-cable with external power source).
