Rev B5 USB issue

Hi ,

We have rev B5 Beagle Board. pin 4 and pin 5 of OTG port is sorted and
externel power supply is given to the beagle board.
We have connected 4 port IO Gear USB Hub to the beagle. Externel supply is
given to the USB hub.
We are using 512 MB SD card where we have copied all the files according to
the following link
http://code.google.com/p/beagleboard/wiki/BeagleBoardDiagnostics
Now if I am connecting USB mouse then click event is not working. Beagle
Board is not showing any new connection in dmesg.
How to get rid of this problem. We are trying hard from last 3-4 days. Is
this the issue of Kernel Image or connection or Rev B5
Beagle Board or IO Gear 4 port USB Hub?

Regards,
Vineet

Vineet,

I have seen that USB devices are not hot pluggable. Hence, connect all the required devices (SD card, Mouse etc.) to the HUB and then power on the Beagle.

Let me know if this works.

Nazmul,

I have tried all the combinations but neither mouse click event nor
keyboard event works. If I try mouse or Keyboard alone connecting to
the board otg port directly then click event n Keyboard event works
fine. I have tried all the HUBs IOGEAR and many more except Cyber
power Hub. Can you please rectify the problem whther it is Rev B5
Beagle Board OTG USB port problem or 4 port Hub problem.
In some of the discussion, I read Rev B5 OTG USB is failure most of
the times and unstable too.

Vineet,

I’m facing a different issue though. I’m using USB absed Ethernet adapetr through a HUB. But at the sametime if i connect anyother USB device to the HUB and intiate a data transfer, the system crashes. Can i know which uImage is used by you? i’m using the pre-built uImage aviallble on the site.

Nazmul,

I am using uImage 2.6.22.18 from http://code.google.com/p/beagleboard/wiki/BeagleSourceCode
For me too USB dongle is not working. If I connect USB HUB and USB
Mouse,USB to ethernet converter,USB Keyboard
then no any USB device is working for Beagle Board. Beagle is not
detecting the other devices itself.
Does your Rev B5 Beagle board detecting any other USB device connected
to your USB Hub?

Vineet,

Ditto is the case here. I feel there is some issue with the USB host controller driver. Trying to find if there are any patches or some other uImage.

the existing code base works fine for most of the hubs, this might
fail for USB ethernet dongles - connect your ethernet dongle to
windows or linux machine and identify the driver it is referring to -
then correspondingly enable the same in menuconfig and re-compile the
code base (uImage)

Sometimes I have seen issues with USB cable itself, if it is not of a
good quality it will affect in connecting multiple device.

Hi Nazmul n Syed,

I got my board working with other USB devices along with USB Hub. The
mistake was I was not connecting Beagle board OTG cable to USB Hub
Male connecter which expects mater device input so that it can source
the output to any of the 4 USB devices. So now my USB keyboard, Mouse
as well as Ethernet is working..

Thx,
Vineet
