Re: USB 2.0 OTG on N810
 
So, to get USB host mode working on the N800, according to the thread that LurkerN directed us to, starting with this post, you need to do the following:

1. Flash your N800 with OS2008
2. become root
3. enter:

echo host > /sys/devices/platform/musb_hdrc/mode

4. plug in your hub / keyboard / flash drive / digital camera
5. N800 complains about not recognizing the device
6. Device works anyway!

If you have the correct cable, you do not need to enter anything... it is fully transparent.

Isn't that only for devices that support OTG?

Yeah, people trying to make OTG work with the N800 are reporting intermittent problems. I think the main problem is that the N800 doesn't have the right sort of connector (Mini AB?) for OTG and auto-mode-switching.

When OS2008 is finally released to the general public (or I finally get too impatient and download the beta, whichever comes first), I'll write a couple of simple one-line scripts to switch between USB modes.

I'll have the cable next week, when I willl be able to confirm what I just said. However some people DID report fully transparent operation with "norrmal" devices.

This is still about USB OTG on the N810, right?

I know more people have N800's, but there's already a huge thread about USB host mode on the N800.

Where did you get your cable, convulted?

Is this the necessary cable for USB OTG for the N810?

You can't buy directly from them, but it's a start is someone at least makes it.

Let us know when you get it, or at least what type it is and where you found it. I'm not totally clear on what kind it should be.

Yeah but how much of a draw is the external flash memory on the unit?

Digital camera? You mean accessing the photos stored one the memory card, not the camera itself? Although, it would be interesting if we could connect a USB webcam.
