Hi guys - anyone know of a way without modifying a usb cable to make the desire draw full power from a USB socket, 1A instead of 500mA?
Cheers
Kev
No because the phone detects that its connected to a USB port because the 2 data pins are not shorted out ... u have to mod the wire. But then u wont be able to us the wire to connect the phone to ur pc

I seriously suggest that if you want a tutorial for shorting two lines of a USB cable then you shouldn't be attempting it at all.
Some motherboards can improve usb power up to 3x, but I don't know if it works with HTC Phones, I know that it works with Apple

True, my ASUS mobo supports it with iphone and ipad but not with iPod classic that i have though, weird.
nope, im fully aware how to short the data lines to get the 1A charge rate, but im sure there must be a Kernel mod that can enable this?
Prynhawn da, KevAmiga
Kernel mod for what?
The specification for USB is 500mA per port, some PC motherboards are able to provide more, but not so many. I mean the limitation is the PC side.
If you want more current, you need to bridge ports.
Regards
Some very new laptops like the recent Thinkpads privide an option where you can "convert" a USB port (the yellow painted one) to an always-on 1A USB port. I'm pretty sure it charges my Desire as fast as the standard AC adapter. On my older desktop pc though, there's no chance of enabling that, even though the MoBo does have USB3. It just takes ages..
I am also looking for a tut please. ^^
it takes ages to charge via laptop and sometimes I have no other options

Kernel mod is available. It charges full power from a usb 2.0. Gingercakes kernel. Desire development section.
USB cables have four wires. Two for data and two for power.
If you want to modify a cable so that the phone will try to draw full power, you just need to short out the two data lines. From this, the device will think it's attached to an AC source.
In most USB cables, the data lines are the green and blue/white ones. The red and black are power.

I just discovered -- accidentally -- that a standard mini USB plug not only fits in the Touch Pro's proprietary plug, but also charges and syncs normally!
To clarify (I hope):
* the Touch Pro's USB plug is shaped like this: l==/
* while a normal mini USB plug looks like this: \==/
Does this make sense?
Like most people, I have lots of normal USB cables lying around, and only one HTC type thing... Can anyone tell if it's totally ok to use a standard mini USB cable instead of HTC's "special" one? It can't damage anything electronically?

Yes,that's normal thing it works. Different shape is present,because the same connector supplies also A/V signals. These pins are located opposite normal USB wires on the middle pin-plate(5 pins standard USB,6 pins Audio/Video). That's the difference and reason,why normal cable works with HTC devices.
Also I think the reason it's shaped like that is to stop you plugging the HTC one into other devices. Could be wrong though

Cool, now I can use my collection of standard USB cables so I don't have to carry that one HTC cable around everywhere.

That makes sense. So HTC cable in normal USB plug: no, normal USB cable in HTC plug: yes.
Yes,the reason is that,you cannot use accessories(handset,adapters) on standart type models. Also all standart chargers are working,because charging pins are located on USB side.
Fuze Charging issues
Just to let eveyone know I originally tried to charge my Fuze using my old Tilt charger and the Fuze got hot and while it charged it took forever. I then switched to the charger supplied with the fuze and there was no heat and the devise charged very quickly. I don't know why but I thought eveyone should know
the raphael charger is 1A, while most chargers are 300-500mA, hence the slower charging. The heat shouldn't be though... so check if you get a nice and clean voltage
So simple question, does anyone know (have tasted) if Touchpad supports OTG like for example Galaxy S2?
I bought these from DX: http://www.dealextreme.com/p/micro-usb-on-the-go-host-otg-adapter-pair-50774 and is working great with my Galaxy S2, but can it be used for Touchpad?
First, it is TESTED.
Second, Nope no native support yet, might have to wait till android port is complete, might take a couple of months.
[Q] USB OTG?
That's pretty cool, keep up the work.
Does anyone have ubuntu chrooted to check if the usb module is reporting anything?
kinda pre emptively ordered one in hope.

The Touchpad doesn't have a powered port is the only problem - so provide power to whatever device and you're good to go.
what about a external HDD with its own powe supply, will it work..
unfortunately, i'm still waiting for my TP so cant test
Does it work with your HD2?
If so, there is no reason not to work with TP
(Hint: HD2 has same kind of usb host capabilities that needs external power supply)
So was it ever established whether or not USB OTG works on the Touchpad? Sorry to necro-post, but I picked up a touchpad during the firesale, have been loving it with first WebOS then CM9, and since I ordered a USB OTG adapter for my GSIII (this friday!) I was curious if there was anything I needed to know about using OTG with the HPTP.
It just works with a powered adapter. Nothing more to it then that. I've plugged almost everything into mine!

Thanks for the links, will see if I can get the needed cables etc from eBay/Amazon
Thanks for the help. My OTG cable and other things from Monoprice should've come yesterday, so hopefully I'll have them tomorrow. By powered adapter, do you mean something like a powered USB hub? Although I didn't get that OTG cable for the touchpad, it'd be a nice treat to be able to use it with that, it would definitely make moving movies around a lot easier.
EDIT (10/19): Dangit, they didn't come today. I'll have to see what's up, because they've been in my area for a while according to tracking just not coming.
Yes, u will have to use either a powered USB hub or get power from a USB charger that doesn't have the data +/- pins shorted internally (purchased or modified). If u plug device (ie phone) into charger and it says "ac charging" that means the data pins are shorted.

Alright, thanks. I think I need to get a powered hub for my laptop (which I am currently using as a desktop with external monitor and keyboard) so I there may be a happy coincidence here.
Also, just checked on my touchpad, and the HP charger says charging (AC) as well as my phone charger, which I think started life destined for some Blackberry.
The powered hub should work though, and that would make a great machine for typing and working in bed as opposed to my laptop burning my thighs off.

I just verified that if you get the Micro USB Host OTG Cable With USB power ($6 from AppleCable on Ebay) that Ramjet73 mentioned (or this one), it will work with any standard USB charger (ie the 1 Amp HTC or 2 Amp HP Touchpad Charger) because the USB Power Connector is Isolated. I also picked up Applecable's USB 2.0 3 Port Hub with data Sync Charger cable for $7 (I may try to modify it to be a USB OTG powered hub with this).
I will be updating the OTG thread I mentioned earlier. See attached:
I've never successfully used OTG. I've bought 2 cables.

I've received a bad one before. Cut it open to verify the id pin hadn't been tied to ground like it was supposed to be. I can verify that OTG is enabled with the CM9 Nightly and jcsullin's latest Cm10.

I'm sorry if this has been asked before. I tried searching but nothing came up.
Is there any way to charge a Galaxy Note 10.1 NT-8020 AND synch the data at the same time via a USB port? Right now I use the stock charger and cable together with MyPhoneExplorer (Android app) to synch the data via Wi-Fi.
I know if I use the original Sammy cable plugged into a USB port on a desktop PC, I can synch the data but only charge if I switch off the device. I assume this is because there's not enough current available for charging from the USB port. But is there something different about the cable itself?
If it's just a case of insufficient current, I should be able to charge/synch via a powered USB hub but the one I tried just now doesn't work either. If it's just a question of buying the right type of powered hub, then can anyone suggest make and model?
Thanks in advance.

Thanks. That's what I was hoping so might risk buying a hub I saw that claims to deliver 2A to the USB ports. I tried an old 10-way USB hub that has a 2A PSU but this can't charge the Note while it's switched on so obviously it's not supplying enough current to the ports. I kinda imagined it would deliver 2A to one port or 200Ma to all 10 or something like that..

Rats! Just found out this product is a charger only ie no data ports so that's no good. There must be some technical reason why an external, powered USB data port hub can't be made to deliver 2A or so.
Hi guys
What are you using to power your Tab S and have a hard drive etc connected
at the same time?
Looking for the smallest possible option to limit bulkiness
Thanks!!
what about this cable.

John.
Yeah looks good....what cables are you guys using for charging and host at the same time?
I heard its not recommended to use an external hard drive without supplying power to the Tab S
Yeah, your right about using an external power supply when using an portable hdd with your tablet as it uses too much power by the hdd, the cable i linked above has an microusb socket for you to plug your tablet usb power adaptor into.
John.
The Y-OTG cables supply power to the OTG device (e.g. SD card USB reader) but not concurrently to the Tab S. Basically all they do is reduce power drain on the TabS. The previous comment to try to use a powered USB hub or a self powered USB device is good advise.

I have to resist the urge to go cheap on power adapters, after i had an car and an mains adapter start smoking in a week and nearly blew-up my HTC M7, I have been looking at the Belkin USB Adapter 2.4amp it comes with an 25.000 damage warranty, they cost between 15-20£ in the UK.

Have you tried the ones on aliexpress.com??
They say its otg and charges at the same time
Samsung tablets no longer supports this function that I know of. They used to have a dock mode that would do usb host charge and hdmi out ending with note 8. I tried all types of resistors and cables so far the lava adapter is the only one that worked. It's a solid 1amp charge with usb function. I wasted more money making and buying cables that said worked but never did. If u want ou cheap buy a usb host cable put a 1ohm to 10k potentiometer in between ground and Id pin turn it slow til u see usb host triggered on the tablet but again it could be a waste of money and not work. I had a tab pro trigger usb host and charge that way but was very unstable current. Any questions let me know.
Hi.
In the user manual it says that the touchscreen my act-up while it is used while the tablet is charging if the power supply is unstable.
A quick Google show this is an common issue for a lot of brands of tablet/phones

Never had a issue I bought the lava 3 port silmulcharge sts 3u it has 3 usb host ports I use one for usb dac 1 for ireless mouse/keyboard 1 for flashdrive. It was made for kiosks to always be plugged in and charging according to the guy at lava I talked to. You have to have a dba to get it direct and the shipping is alot from Canada to us so buy from amazon.
Okay, since this part of the Note 8.0 section is dead, I decided to revive it a bit on an USB cable I upgraded to. It combines the versatility of Apple's megnetic power connector and USB C plug reversal capabilities. So plugging in you USB cable is much easier and does not degrade your USB connector over time. It is the most awsome accessory I ever bought for a device, and has 2.0 Amp charge current capabilities to boot!
Now for the built in bonus item... it has a charge LED to let you know it is either charging or not. No need to wake the device to see if the device is charged. As you all know Note 8.0 devices have no charge LED indecators.
Now the big big big bonus... the cable is cheap and has free shipping. It cost me $6.00 US and came from China via Amazon. There are a few similar devices on Amazon so look for the silver version not the white or what ever.

The cable does everything I have stated. Has reversable connection for both charging and data. The head has circuitry to properly connect the pins without any fuss. The only thing it will not do is high speed usb 3.0 or better. Wish this was a stock option it would have saved me tons of money with oem and high quality replacement cables krapping out on me.
Sorry, I really don't understand....
Could you please post a photo of the cable?
