HID driver hang

[ankita prasad]

Hi,

I have built an HID device driver using the hid class present on the XO.
When I plug my HID device into the XO , I can perform read/write operations
for sometime. But in about  a minutes time, my HID device hangs and I have
to unplug and plug my device to get it working. While trying to figure out
what could be wrong, i found that the recent ubuntu distributions have a bug
where in plugged usb devices stop working after sometime. (
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.15/+bug/68140 )

I want to be sure that the issue is not an issue with the XO distribution.
The OLPC build that is on my XO is 542.3 and the Kernel version is
Linux-2.6.22-2007081.5.olpc.be30006dad097b8. Can anyone out there confirm
that the ubuntu issue is something that is not there in the OLPC
kernel/distribution.

Thanks!
Ankita
