Hi all.

I was looking into USB host support on the Touchpad and I guess I have some good news.

There is fully functional USB Host support, you don't even need to do any SW modification, everything is supported out of the box with one caveat, you need external power.
Support for keyboard, mice, harddrives and cameras is fully built in the default WebOS software.
I guess HP planned to sell their own USB attachments, iPad-style.

The only thing you need is USB OTG cable. Like this: http://www.ebay.com/itm/New-micro-U...781644?pt=PDA_Accessories&hash=item19c7d49acc
Basically just search for "USB OTG cable" on ebay, costs about $3. And USB Y-cable. The only two things you need are OTG microUSB cable and USB Y cable to provide external power. ;)

I am still looking into possibility of self-powered usb host mode, with all the support HP built in for it it almost sounds like a given there must be a way to enable it one way or another. Unfortunately chipset documentation is almost nonexistent.

Yes you can if your powered hub also provides power to the upstream port.
If it does not (like majority of the hubs), then you can use Y cable and simply plug the "power leg" of the Y cable into one of the powered ports of the hub

If im not mistaken the Y cable is to connect to the power supply one arm of the Y to the peripheral of choice the other arm to the power supply. The other end is connected to the mini usb connection of the TP

I'm thinking of buying the TouchPad really soon. I must ask, does this also support card readers, such as storage mounting? And will this include Android at one point too?

Cheers :)

Do you think it would still work through the TouchStone?? ie, just leave your USB whatever plugged into the touchstone and you can just plop the TouchPad down and type/mouse/whatever without issue?

Storage mounting does work.
Android will fully support this as well, of course.

I honestly don't know.
Chances look slim, unless they actually route some of the power to vbus.
I don' t have a touchstone to test, unfortunately.

and would either of those hubs be ok to use? i see one says upstream for micro. just like some feedback from a guy that knows so i dont buy more than i need :)
looks like the second accepts the printer style end not the mini usb looking thing.

i got these:

7-port usb hub $5.85
http://www.ebay.com/itm/220833504114?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

Y cable: $2.02

what about the first hub? second accepts usb and a printer hook-up. and my question is with the y cable it needs 2 male ends? i ordered the otg earlier but 2 males on the y adapter doesnt make sense to plug a keyboard or anything into it. i would figure 1 male to pc for power and a female for device and micro to TP. unless im wrong. not exactly sure y you need the otg if the y cable has a micro and male for power and a female for the device?
