If i had an n900 in my hands, i would use the "mode" sysfs node of the musb driver, valid parameters are "host", "peripheral" and "otg". I'd switch it to the host mode and measured with DMM if there's power on the Vbus and checked the resistance between DM/DP and GND (should be ~15k). I'd connect what's lacking externally and tried attaching some mass-storage device or a mouse.

You can't switch the N900 to host mode via software. It will immediately switch back to "b_idle" from "host".

testarc et al: Seriously. Give it up. Unless you're an electrical engineer or a kernel hacker with an N900 to test with, you're probably not going to add anything new to this topic.

Hi,

Just wondering, has anyone gotten any further with investigating USB OTG support?

I haven't quite made up my mind to buy the N900 yet... the open question about USB OTG is one of thing things holding me back for now, especially with the next Maemo device scheduled to come out this year.

I'm no EE, but I was under the impression from the December 2009 activity in this thread that it still seems like there is a good chance that the hardware supports USB OTG, even though it may need a custom kernel and/or some cable trickery.
