USB-OTG as peripheral

Hi,

Is it posible to test USB_OTG as peripheral by using miniB cable on RevB5 beagleboard.

Thanks & Regards
Tilak

Yes.

Hypothetic question, but perhaps you know the answer: will it be
possible with Rev. C to use the miniB as OTG and to use the second
USB-connector for connecting peripherials at the same time?

That will be possible.

Thats great! Really great! This opens a lot of possibilities! Works
this out of the box with the kernel or has something to be done?

Only with a hub, the EHCI port only supports fullspeed devices and needs a hub for low- and high-speed devices.

Okay, that should be no problem for me: using a hub or only connect a
fullspeed device.

Thanks for the answer, these are very great news.

Minor correction - Just to be totally clear, since USB terminology is tricky
:-),

EHCI => High Speed = 480Mbps
OHCI and UHCI => Full Speed = 12 Mbps
OHCI and UHCI => Low Speed = 1.5 Mbps

The EHCI port therefore only support High speed and needs a hub to connect
to full and/or low speed devices...

My device is EHCI, so this fits exactly. And its a fantastic
possibility to connect the BB to windows and establish a network
connection at the same time :slight_smile:

Hi Robert,

Just to be totally clear – EHCI (480Mbps) and UHCI/OHCI (1.5 and/or 12Mbps)
are host controller types and thereby only valid for USB hosts...

A device is either Low, Full or High speed compliant and not E/U/OHCI...
I think that what you mean is, that your device is a High speed compliant
and therefore fits directly - Right?

Best regards – Enjoy your weekends everybody

Right :wink:

Does, this mean Beagle Rev C has two separate USB controllers inside?
i.e. Separate controller for OTG and USB Host.

Hi Shivdas,

You are completely right :slight_smile:
