Hi Everyone,
I have ported the USB gadget driver (Android gadget) to my hardware
platform, which is running on a PXA27x processor.
Its able to connected with a Windows XP PC (I had modified the driver
INF file to recognize the platform). But after a while, this warning
is popping up in Terminal. What exactly is this?

Also I facing certain problems to my ADB connection. Is it because of
this warning?
Thanks & Regards
