I was surfing the net when i come across this:
.verizon-cellphones.org/motorola-xoom-usb-and-pc-charging-driver-download(dot)html
does this mean that you now can charg the xoom throug the usb interface(i dont own a xoom myself )
No. you cannot charge the Xoom over USB.
Why do people want to use the usb to charge. It would take forever to do that.
Being able to charge over USB in a pinch would be better than nothing if you're without your charger. Plus, my USB car charger can put out 1A, and you can buy iPad specific USB chargers that put out 2A, so it actually wouldn't be much different than the regular charger. It certainly doesn't hurt to have the capability. For all the crazy stuff we hackers add to our devices on XDA, I am blown away that people still ask "why would you want to do that"... Why not?

My car has a USB port built into the stereo, on my Droid when plugged in via USB I could play my music and also have the phone always topped off with a charge... With the Xoom I'd need a charging cable too... Hassle. Guess that's a part of why I keep my Droid around...

Plenty of people have rooted their Xoom's using those charging drivers, they don't do anything for the Xoom other than allow it to work with adb.

From what I have noticed I have yet to have wished that I had a charger SD or the one that came with it as it has a great battery and is more than enough to get me througn the day and i have been neglecting my droid Inc and macbook pro while using my Xoom for 6-8 hours a day plus a gppd 10-15 stand by time

Guys, there are lots of reasons to want to charge over USB. Like, say, when you're on a road trip and won't be spending much time around an outlet. Even if it doesn't charge quickly, if it provides enough juice to keep it from dying, that may be enough. I'm sure motorola sells a car adapter but I'd rather just use the USB chargers I already have.
Can we not make this discussion about if we *should* be able charge over USB, and keep it purely about *how* to charge over USB? I think we all understand that not everyone cares about this feature, but some people do.
So, I heard that there is an official dock that charges it over USB? Or does it use contact points or something else?
If the official dock charges it over USB, it may be simple to mod a USB charger to work with the Xoom.

Agreed. Why does it seem like everyone has such a pissy attitude on this forum? It seems like 75% of all OPs in regards to do something new are negative and completely non-constructive. "No, you can't do that" "why the hell would you want to?" "That sounds useless. I have my phone/laptop/TV/mother for that"
I don't think that I would need the USB trickle charging ability because the battery lasts plenty long (yes, even at 1.5Ghz), but why get on here and make the OP feel like an idiot for trying to spur some innovation?

Hey Guys,
I posted a long comment on the thread in the Moto forums. Hopefully we get a real response from Motorola. So far they have only said "you can't do that", but haven't explained if its a hardware limitation, or if it was just disabled in software (which is my hope).
Here's my comment:

It's really pretty simple why you can't charge over USB. USB does not provide the correct voltage. The Xoom requires 12vdc to charge and USB is only 5vdc. It's like trying to charge your car battery with a charger made for 2 D cells. Amperage does play into charge time but can not be made to compensate for the lack of voltage. If the Xoom were to be modded pretty extensively inside it's possible. You would need to add a step up converter, make the respective connections from the USB port, and have to be willing to void your warranty. All in all it would be easier to carry a car charger. I have one and it works great.

Its is very possible that they included a step-up converter circuit, but later disabled it because they decided it takes too long to charge. The circuit would add less than a dollar to the unit in volumes, so if they wanted to be safe they could have included it and made the decision later if they would use it. That is what I am trying to find out. The high resolution images of the teardown show what may be a stepup circuit by the USB connector, but it is too hard to tell:

what are all these USB chargers on eBay about?
My question is now (and I am sure I've seen it in another thread): How do sellers on eBay get away with advertising generic USB chargers to be used with the Xoom (e.g. this)? Of course, the USB cable has to be provided... I checked yesterday because I want to equip my car with a mount and charger in the future. Either the Chinese have found a way to charge the Xoom via USB or it's all a load of owl droppings! Has anyone tried one of these magic chargers yet?

They put the word Xoom in the auction listing, that's the only thing they did to make this Xoom compatible. Do not buy that.

A lot of people just assume things. I was readings specs for the xoom at another popular android forum. They had listed that not only did it support USB charging, but it supported flash 10.1 as well (which of course it never will).

It should be. Any standard USB cable should do.
try something like this :
www.dicksmith.com.au/product/E6201/milkshake-retractable-cable-usb-to-mini-micro
you can find these cables on ebay.
works well and also does mini usb. be careful some usb to micro usb cables are for charging only and do not have the data lines connected.
Yeah. I've always been amazed by vendor branded usb cables - nokia is guilty too, they try to give the impression that their ones are different but any compliant usb cable will work.
I've just ordered a couple of Micro to Mini USB adapters. I have loads of Mini USB leads at home but only 1 micro USB which is the one that came with the phone.
be careful with those mini to micro usb adapters as a lot of them do not have the data lines connected so they are only useful for charging.
I have a short Nokia CA-101D cable that came with a 5800. Works fine with Samsung i8910, HTC Desire and Desire HD (from my experience) for both data and power.
Cable is 20cm long and can be bought for less than £2 from various places including Amazon and Ebay.
Hope this helps. John

Errrm, no. Mine charges just fine from the USB port on the pc and laptop.
Yeah, can draw up to 500mA from a standard usb port.
lol damn i got a crappy usb connection then! I say there watching 60% for over an hour so I was left thinking it didn't charge, only transferred data!
IMO USB charges should be avoided, it should be possible to turn off charging.
While it is not exactly harmful to the battery like it used to be, I have the pretty strong feeling that low-ampere charges suck. Try it your self one day, after your battery is fully conditioned. Go down to like 40% of charge and then leave it at some USB port overnight. Then watch how quickly the power drains the next day. Then compare that to a charge from 40% to full on a high ampere (1000-1200mah) connections like the mains charger or a good car charger.
The charge seems to last longer. I have noticed this with multiple USB-charging devices now and I think it has to do with the amperage / time of the charger. The lower it is, the longer the charge takes the shallower the carged battery is.
That was the feeling I had too psychotic, but when I claimed this at a different forum I was laughed at and told that a full charge is a full charge except that a USB-charge takes longer... Do you have anything to back it up?
If looking to charge in the car...
... then aren't there specific USB cables where a couple of the pins are shorted or something so that the car panel opens? Seen a thread on this site, but can't find it right now!

Actually I read somewhere that a computer slow charge actually gives you slightly more capacity. Can't remember where though! makes sense since fast charges usually get a bit lower capacity.

I think that's the case. Slow charging via USB also doesn't heat the battery up so much, so is kinder to it.

To be honest....not many. The connector the Xoom uses is a pain, not included with laptop universal chargers. I think there are some Nokia phones that take the same size so you may find it included in some phone universal charger sets, but since the Xoom can't be charged via USB cable like phones your options are pretty limited. Contact Moto or Verizon and see if you can buy a new Xoom charger.

Pure hardware...the microUSB port on the Xoom isn't designed to recharge the battery...and the voltage the USB cable could carry would likely not be enough to make much of a difference, like on the iPad.

I haven't seen anything any cheaper. So if you really need it then I would cough up the $30 & be done. I have seen them as much as $50.
Oh, you need the wall wart. You'll have to cough it up, as far as I can tell. I tried using the one from my Droid and it wouldn't charge, so just any wall adapter won't do.
You might find one on ebay as a last budget resort.
I could be wrong, but I read somewhere (probably here) that the charger just has to be able to give 12V for the transformer to charge correctly. So a switchable power-supply that supports 12V output and has a usb female plug should work fine. I have the Goobay NTS 1500 MW in my amazon wishlist (in Germany) and only wait for an occasion to order. But check on it before buying or wait until someone comes and confirms this. I'm sorry that I can't give you a link...
Excluding the DIY charging stuff we have posted around here, or cooking up sth able to do the job, I don't think you're going to be able to find anything. Maybe eBay or shopping.google.com at best, might have sth cheaper.
Last time I was in Fry's and saw the price, I was happy mine has had the easy life.

Not sure what the voltage would be...hmmm...maybe I should go check it out, that is if you don't do it and report back before me......it was only like $15.
The TF101 uses the extra pins associated with USB 3.0, so any cable you use should be 3.0 not 2.0.
Yes, that's true. But I believe this is only important if one wants to use an extension cable to extend the length of the original cable. If you use the original cable and plug it directly into a USB-port it shouldn't matter whether it is USB 2 or 3 as long as it supplys 12V DC

To bad the Charge won't draw more than ~0.8A... Also, it is the charger causing the phone to go to mass storage mode, not the cable. A microUSB cable is a microUSB cable, and if the cable says "charging only" they have the data pins shorted out (I believe that's what is done) and it really isn't fixing the root cause of the issue.

The only way you could speed up charging would be to modify it via the kernel, or try to force load a module that does the same thing. Odds are the fastcharger script just gets the system to recognize USB charging as a wall charger. Either way, I wouldn't recommend using anything that says it'll make your phone charge faster unless there was SIGNIFICANT data to support the claim as well as evidence that it doesn't harm the hardware.
Charging the battery too fast is very dangerous too. I tried "supercharging" one of my batteries and it almost caught fire.

Samsung smartphones and Tablets charge in std mode (Charging USB) unless the two data wires are "shorted". (I have seen it done directly in a high speed charge only cable or in the Samsung chargers. Some say they use a resistor.) When the data pins are "shorted", Samsung switches to high speed charging. (Charging AC). I have been harassing a factory overseas for a dual car charger (2100mA) with one std. Port (iPad) and one Samsung port. It should be available soon.

I haven't tried another car charger personally, but can vouch for the Verizon one. Always works for me and I just leave it plugged in the lighter outlet in my center console so whenever I need it, it's easy and quick to plug in the phone. Also has the scrunchy style cord to keep things neat. But at the same time, it makes it more difficult to use the phone while it's plugged in as it keeps wanting to pull back lol
I have read so many threads with problem x solved by using a quality USB cable, and yet I still find others arguing that there is no difference in cheap cables. In-fact i have just had a discussion about this with a friend yesterday so i thought i would just let everyone know - USE A GOOD CABLE!
To test this I used an ebay cable, oem samsung, oem moto, and a case logic cable. I then simply transferred a small 6 mb file and a larger 200mb file to the phone.
Ebay - phone wouldn't even connect to pc.
Sam - both worked
Moto - both worked
Case - 6 mb worked, 200 started and then completely froze forcing phone reboot.
So again, especially when flashing, use a good cable!
Good to know. Thanks
Just another heads up... My wife has a Motorola and I have the siii. Using my siii cable, both of our phones charge at least three times faster. Using the Motorola cable, both of our phones charge much slower.
Another heads up... Get the best of both worlds, high quality and low price on a usb cable. Go to monoprice.com!

Most Likely those talking about difference in Cables could be talking about how each manufacture alters their cable.
For example, Moto and Samsung have a Resister that links 2 of the 5 pins which is hidden in the plastic. Reason for this is, Car docks, it would tell phone to open car dock App etc, Same for media docks.
Charger usb cables are same because some phones can handle a higher amp of charging which charges faster while a standard usb cable needs to made to have a limit to not fry the device it is being used on.
Hope This helps, i know it did when I learned this,. Now it makes more reasons and ideas for Mods...LOL
This is news??
Duh.

Isn't it just safe to use the USB cable that came with the device?

I'll second that, best place to get almost any cable you can think of. I have yet to be disappointed.

If you're using a charger for a different device, it's likely that they have different amperage. A 2 amp charger will charge your phone a LOT faster than, say, the 0.5 amps off your computer's USB port. In this case, it's not the USB cable itself, but the amperage of the transformer in the charger. Some may argue that the slower charge is "better" and will help your battery last longer.
If you're using the same charger with different USB cables, then this is news.
I haven't even used the OEM cable that came with my GSIII. I picked up a 6 foot no name USB cable from newegg for $1.39 and it works fine.

Was going to point this exact thing out. It is also possible the cables could be rated for passing different rates but it is much more likely that something is putting off more power so it charges faster. I do tend to agree though that slower is better since you can pull the plug faster and not overcharge
Over time I end up having loose connection problems with virtually any microusb cable i buy, including from monoprice. At first the cable plugs into the phone fine and charges. Overtime somehow the microusb part that goes in the phone is looser in the phone than before, and i have to angle my phone in way to get it to start charging. The slightest movement causes the charging to stop. I have had this problem with almost every micro usb cable i ever owned ever since I got an htc thunderbolt and the problem continues now with my s3.

going to mono price. I'll report the results.
One thing to keep in mind also is that most, if not all, USB cables aren't shielded so the longer they are they degrade the transfer speeds etc. I don't think it would make a difference for charging, but to transfer data a shorter higher quality cable would be your best bet. I don't know if the degradation would be noticeable tho...

You wont be disappointed. Quality products at great prices. They also stand behind their products if, in the rare event, you have a problem with one.

I have read so many threads with problem x solved by using a quality USB cable, and yet I still find others arguing that there is no difference in cheap cables. In-fact i have just had a discussion about this with a friend yesterday so i thought i would just let everyone know - USE A GOOD CABLE!
To test this I used an ebay cable, oem samsung, oem moto, and a case logic cable. I then simply transferred a small 6 mb file and a larger 200mb file to the phone.
Ebay - phone wouldn't even connect to pc.
Sam - both worked
Moto - both worked
Case - 6 mb worked, 200 started and then completely froze forcing phone reboot.
So again, especially when flashing, use a good cable!

When you say the transfer started and then froze, I would have to ask what ROM you're running. If it's TW or TW-based, I'd be much more willing to blame the software than the cable. Using Samsung's MTP interface, I have had plenty of large file transfers crap out using both high and low quality cables.
Either way, this test is hardly complete. Obviously somethings wrong with the Ebay cable, but for the other tests, you need to run them more than once. To give any statistical significance to the data, the tests have to be run a bunch of times. Otherwise it is (as far as you know) just luck.
Also, as others have said, I think the primary differences between cheap and "quality" usb cables are
Amperage (which is mostly due to the charger, not the cable, but generally you want a cable that can handle it)
Quality of the connector (cheap cables generally have flimsy connectors)
Quality of construction/Durability (may work fine, but die after a month or two).
I don't think data transfer is something that is really impacted much by the quality of the cable (until you hit that point where the cheap cable just stops working). Getting back to my earlier point about the limited testing, I think if you ran the same test a whole bunch of times (like 100 times for each file on each cable), you'd find that as long as the cable actually works (which seems to exclude the ebay one), they'd probably perform about the same on average.
Just my two cents.
