Hi Ytai,
I've updated the firmware to 0500 and was still having the problem so I
swapped out to a new IOIO and I'm having the same issue so it looks like it
is my PCB /or the software... which you probably already guessed it wasn't
the IOIO. I'm about to test with another version of my PCB. I
Device and host are standard USB terminology. Loosely speaking, the host is
the one providing power and the one requiring to have intimate knowledge of
the device's interface.
In the case of the IOIO/Android, either way works (i.e. the IOIO can act
either as a host or device). In your case, you're
Multiple threads are indeed the recommended way of doing what you want. Do
not confuse that with having multiple *IOIOThreads*, which is *not* what
you want.
A thread is automatically created by the IOIO framework for every possible
IOIO connection. This is some internal bookkeeping that is not
There is now a simple windows app that demonstrates basic functionality.

I have now had a chance to test using the boot pin sequence, on both a
windows 7 machine and a Raspberry Pi.
When started in boot mode (boot pin grounded and then un-grounded) it is
enumerated by both the Windows 7 machine and the Raspberry Pi.
However this is where things start to get a bit
1. The IOIO apps, such as HelloIOIO are not intended to work against the
IOIO bootloader but rather against the normal app firmware.
2. If the IOIO doesn't enumerate don't bother moving on.
3. When you do get it working, I strongly recommend that you use the
-Dioio.SerialPorts argument as the log
Thanks for that Ytai!
Turns out it was the cables we were using all along! What a pain.

Ok, thanks.

I don't think that's possible. The USB protocol uses the VBUS line for
detecting the presence of a host.
One thing you can possibly do is use the Android in host mode (the IOIO
being a device). In this case you
Hey Guys,
I am having a lot of trouble with the JST-PH connector which is on the
board of the IOIO OTG.
It is very hard to find and also it seems that there is no standard for the
positive and negative side. I burned two ioios because of the cables I
bought from China.
