USB Hub

Dear all,

Iam Working on Beagle board from last one week. I want to enable usb based wi-fi on it. so Iam unable to get USB hub for the otg on Beagle board. Intially to get that functionality, I used mini-A to usb-A male connector and usb-A female to usb-A female but it seems to be not working with that connection. can any one please help me out where is the mini-A to usb-A female connectors availble in India?
And another doubt is I found one “usb host” slot on the board so can I directly mount the usb host on that or any additional circuitary required?? Please help me out…330.gif

Hi,

I am working on beagle board. I want toggle some GPIo pins (GPIO 132 - 138 pin), Is there any code for this?
How to access these GPIO pins and how to make these bits High and Low?

Sanju,

There is some discussion of programming GPIO pins in the thread:

Hope this helps.

Iam Working on Beagle board from last one week. I want to enable
usb based wi-fi on it. so Iam unable to get USB hub for the otg
on Beagle board. Intially to get that functionality, I used mini-A
to usb-A male connector and usb-A female to usb-A female but it
seems to be not working with that connection.

I'm not sure I follow your wiring. According to above:
  A-mini(-male?)<=>A-male and A-female<=>A-female

How can these two cables connect from Beagle to a HUB?
Where did you get a A-female<=>A-female cable - I have never seen such one
:slight_smile:
Is pin 4 and 5 shorted as described in: Beagleboard:Main Page - eLinux.org

And another doubt is I found one "usb host" slot on the board so can I

directly mount the > usb host on that or any additional circuitary
required?? Please help me out..

The connector is un-mounted together with the USB "ULPI2USB-circuitry",
since the circuit doesn't work on the Rev B boards. This will be fixed on
the Rev C boards coming up later this months. It's therefore unfortunately
not that as easy as soldering the USB host connector :slight_smile:

This is the female A <=> female A cable

OK – Agree – I would however call this a converter and not a cable – But I guess this is a fight on words. The main point is, that this cable/converter didn’t pop up in my mind, and I still don’t know how this would connect/fit into a HUB J

As I understand, he will connect like this: BeagleBoard (miniA) => miniA to A male <=> female A to female A <=> A male to mini A <= HUB (miniA)
Am I right?

As I understand, he will connect like this:
BeagleBoard (miniA) => miniA to A male <=>
                       female A to female A <=>
                       A male to mini A <= HUB (miniA)
Am I right?

I don't know, but that would be my assumption as well, and in that case he
might hit the problem of not shorting pin 4 & 5 as described in:

Hi all,
What you expected is correct I connected like
BeagleBoard (miniA) => miniA to A male <=>
female A to female A <=>
USB A male hub.

But it seems to be not working and mini A <=> A male which i connected to PC that is working like network emulator.
Probably i should try out with shorting 4 and 5 pin of OTG. The main problem is iam not getting exact converter which beagle board has given in the Website.

I will try out the above connection if it is not working ill defenetly post my problem.

Thank you
