Hi again, in my case the LEDs don't blink at all when transmitting or
receiving. As I said before, I found them blinking when I was on the wrong
controller.




Also a very good hint was the maybe lack of power through one of these USB

You have to check it with the manufacturer. Look for its datasheet. I'm
sure there are other ways.
In linux, I used this command line $ lspci|grep USB

And here is the output in my case:
00:1a.0 USB controller: Intel Corporation 5 Series/3400 Series Chipset USB2
Enhanced Host Controller (rev 06)
00:1d.0 USB controller: Intel Corporation 5 Series/3400 Series Chipset USB2
Enhanced Host Controller (rev 06)
04:00.0 USB controller: Renesas Technology Corp. uPD720202 USB 3.0 Host
Controller (rev 02)
05:00.0 USB controller: NEC Corporation uPD720200 USB 3.0 Host Controller
(rev 03)

You can see that I've the old one, uPD720200, which came with the
motherboard.
uPD720202 is the one we bought later, and works OK.
You will find quite confusing info since Renesas and NEC have merged :_D

well, in fact I'm not working with openBTS any more, I switched to OAI. But
I can vaguely remember that someone had issues with virtualization. You'll
find helpful the mailing list archive. Maybe someone from ettus could give
you more info, mailing list cc'ed.
