I have attempted the same test on an Asus Transformer Prime Tf201 (ICS), and I *don't* get bursty data transmission. So it must be something to do with the Android port to Panda-board that is the problem.
I will continue to investigate, but in the mean-time if anyone has any thoughts, then please feel free to let me know? -- unsubscribe: android-porting+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-porting
