I'd like to connect to android powered tablet several peripherals (through micro usb I guess) like: couple of rs-232 ports, keyboard and even one rj12 port.. as I guess it's possible to create usb-hub-device to all this functions, and develop drivers for it.. I just never dealt with stuff like this before. What of it is possible and mb android have built-in support of some interfaces and devices..? goal is to make cheapest solid touch tablet based complete device.
For this to work, your Phone needs special USB-OTG-capable hardware. I doubt it has. If you don't know what it is and why it is definitely needed, google for USB OTG (on-the-go).
Of course, a simple USB host connector would do as well, but no phone has one (but some tablets do).
No android phone out now has USB host support, nor the drivers to run any peripherals.
thx for answrs, looks like its possible but I need to port usbhost module to device kernel.. and perpherals drivers modules too.
Hi, can anyone who owns a XOOM pls let me know if you can plug in:
1) a USB flash drive to the XOOM, and view and open files on the drive?
2) an external hard drive and view and access files from your XOOM
Many thanks

Does the Xoom have a USB port? Pretty sure it only has MicroUSB. I guess they do have microusb flash drives not that I look.
Hi. Yup its only got micro USB, but I guess you could use the included adapter cable to plug in a flash drive.... we don't have the XOOM here yet, but the functionality of being able to connect a flash drive, move files e.g. PDF or .doc and then view them is important to me.

As of today what you want is not avab. The cable it comes with doesn't take input. They do have a cable online that will do this one day, but doesn't do it yet.

The cable that Motorola "will" be selling is a micro-usb to standard usb (female) adapter. I'll look around for the sources, but I know that I saw this detailed in a few videos from Motorola techs and at least one reviewer site.
The cable is not just a straight conversion of form factor, but has the necessary pinout to instruct the Xoom to jump into usb host mode. From the reports that I saw, it would absolutely provide the ability to plug usb drives, cameras and other accessories into the xoom for direct access. In fact, the reviewer that I saw, made a comment that they had verified the functionality by plugging in a couple usb keyboards... supposedly worked like a champ.
Lame that we need a "special" adapter, but I can imagine that if it is just a pinout issue, it may be possible for the good folks here at XDA to craft a software solution that would allow us to bypass the motorola-branded cable... It would have been WAY cooler if it was a standard usb port, like some of the other tablets on the horizon.
Thanks. They mention in many reviews and I think Google mentioned it too that you can attach a mouse or keyboard by cable (I know about Bluetooth) which suggests that it should support input, so is it just a hardware interface thing or an actual firmware OS/software issue?
Edit: thanks for the great response gigglebox.... we posted simultaneously
Is this it?

Visually, yeah. Looks like they took it off their site for some reason. In fact the only times that I saw this on Moto's site, was in the day or 2 leading up to the launch... when typing in xoom into the search bar on their landing page, it would spit out a drop-down menu listing the Camera Connection Kit (by name and pic).
I dont like the fact that they call it a "camera connection", but they werent pulling any punches about it serving as a host. They did note that the external storage (thumbdrives, etc) were not yet supported, but that they would be. The cameras and (according to them) keyboards were working now.
I believe it is possible but right now it is a software limitation.

Agreed, the engineer from moto definitely says the hardware should accept any usb 2.0 or higher device, but it's a software issue. Toshiba have a straight usb and a micro usb port on their device so hopefully they're working on this.
We don't have the XOOM here yet, but hopefully by the time it becomes available (approx April) we might have the option of the Toshiba as well.
I use this USB host cable and it works great. Have tested it with my 750gb Oyen and 320gb WD Passport external HDD's, several usb flash drives (8-16gb), San disk USB memory card reader, and a USB keyboard.
For those having issues getting their Xoom to recognize USB storage devices here's what I've got and did to get it to work: I flashed my XOOM (3.1) to the 2.6.36.4 Tiamat_Xoom-v1.4.4-Full_Throttle Kernel and was unable to get the USBMount to recognize drives or storage at first. I installed USB Mass Storage Watcher from the market (it's free) and it works awesome! Can mount any storage I want (NTFS, FAT16/32, HFS, HFS+, EXT2, ETX3, EXT4) with any capacity. I think this app will work with any rooted Xoom (or other devices). Under my Kernel my USB host is located under/usbOTG.
Hope this helps.
FYI ... I've checked it and stock ROM Xoom without root is able to operate standard PC keyboard/mouse using basic one-to-one usb->microusb adapter (without any electronics onboard).
Probably with proper dual socket usb adapter (also without electronics onboard) it would be possible to connect both keyboard and mouse at once.

if you have a Logitech keyboard and mouse that connect by the unifying receiver,or mostly any keyboard+mouse combo that connects by one receiver, then only a standard OTG cable should work.
Does anyone know if the new host mode interface in 3.1 supports a USB Ethernet adapter? I'd like to be able to use one of these when I'm traveling and at a hotel that only has wired connections.

I wouldn't think so you would probably need some proprietary drivers to make the adapter work
Why not go with a small travel router? It's one more thing to carry but would satisfy the lan line only issue.
This one got some good reviews, not too pricey:

What about other uses? I'd love to have a usb serial adapter and a usb ethernet adapter so I can use the xoom for adminning devices and such.
linux drivers
Android uses a normal linux kernel, so anything supported by linux will be supported. I have used an external wifi, ethernet and usb-serial with an Android phone.
Hi all
I would like to connect my canon a470 powershot to my
Wifi only xoom, running tiamat 1.4.4 and honeycomb,
through an otg cable.the cable works and I can access USB
pens reading the content.Now as my camera does not
provide usb mass storage access but only mtp/ptp I cannot
manage to access photos directly plugging the USB cable.
I read that Verizon camera kit cable supports ptp on
Honeycomb systems but how? Is there any app or .ko
needed or is a compatibility issue related to my camera?
Thanks

I have the Motorola Xoom "camera " otg host cable. That's all the "kit " contains. I'm running the Tiamat ROM and I can not access my Canon Powershot either. So, if you have a working otg host cable, don't waste your money....
really ? nothing more than a simple OTG cable ? Thanks for the advice ! How is it supposed to work on stock ROM's if UMS is disabled ?
I 'm sure that there must a library for ptp/mtp on android: I read that some people had this feature working, being able to access photos (stored on the camera) through the stock gallery app.
Maybe the OTG cable is not enough...
Could be the camera brand. I have no idea though. I don't need to connect any of my cameras to my xoom.
Bumpity bump
Any resolution to this?
I have USB sticks working too but not ptp supported devices...
I'm having the same problem with my Canon 5D. Also tried Canon Ixus 130 and that didn't work either. I just tried installing the stock Australian image and then installing the 3.1 update and that does not work either... I asked around and found people that also had a canon 5D and Xoom and the combo worked for them.
that is so weird
I wish someone can shed some light on this...is this inherent with 3.1?
Do not know will this help in any meaningful way but did anyone tried connecting A470 running chdk? I do not have Xoom but there exist plethora of scripts for canon low end cameras making them just a little bit more useful. Higher end cameras have another way of enhancement with different program setting. Just my to cents...
Can I use this or this kind of hub and using those all port simultaneously? I already know that the phone supports hdmi out and there is no problem since android 10 usually but I coudn't get this clearly from anywhere. What I exactly want to know is If I can achieve complete radio silence state and still using the phone as android desktop. Like… Connect internet through RJ45, downloading file to USB memory while using hdmi and USB keyboard&mouse.
