[srslte-users] Need Help with srsLTE for LimeSDR USB

[Andre Puschmann]

Hey,

we recommend using the Lime through Soapy rather than using the Soapy
driver for UHD. So deinstall that. Make sure the Lime doesn't get picked
up when you run `uhd_usrp_probe`. Note that srsLTE will pick any UHD
devices first before even checking Soapy.

Cheers
Andre
