I'm using a beaglebone to stream videos over wifi. For this, I'm testing
two wifi adapters:
rtwn0: MAC/BB RTL8188CUS, RF 6052 1T1R
run0: MAC/BBP RT5390 (rev 0x0502), RF RT5370 (MIMO 1T1R), address
e8:4e:06:3c:fd:5d
Both adapters works fine at low bit rate (300 Kbps), but when I use a

I'm using a USB wifi dongle to connect my baglebone black. This dongle
uses the driver rtwn/rtwn_usb.
This driver exhibits a very low performance on both, beaglebone and a
Intel Core 2 Duo notebook. With -ht and without -ht on the ficonfig the
performance is something like this:

FYI: Most of the USB control and data memory is coherently allocated
and don't need barriers. You can try capturing a trace using usbdump,

I wrote these two small programs to help debug a problem that I think I
have found when using urtwn driver in a baglebone black. The problem is
100% reproducible.
In a server machine I run:
serverUDP 2508
In beaglebone black I run:
./clientUDP servername 2508 9216 0

Maybe a electric problem? I'm using a
external power source to USB HUB.

I'm using a beaglebone black to stream video over UDP. I wrote a
software and have tested it using a urtwn device + webcam Logitech C920.
All is connected using a USB hub with external power source. So urtwn
and webcam, both are plugged in the same USB hub. When I plug the hub
