hello:

I installed the osmo-NITB on ubuntu18.04, including osmo-trx,osmo-bts,and openbsc.

The following is the print messages when these three applications start up.

when the osmo-bts-trx launched later, the following messages will arise,  shows that the osmo-trx received the  'POWEROFF' command and feed back the 'RESPONSE' to osmo-bts-trx.

In a word, the hardware USRP  TX/RX LED  has not been lighted, it seems not work. How to poweron it?
