LMS_Open with multiple LimeSDRs

Projects LimeSDR
1

Hi,
I am trying to use LimeSuite to open multiple LimeSDRs.
When I open one device using LMS_Open it works fine.
However trying to open more than 1 device and it fails on the 2nd and following devices.
I am using the names return from LMS_GetDeviceList
LMS_Open is not returning the error it is an error from libusb “Cannot claim interface”
indicating the device is already in use.

Suggestions please on the back of a postcard

This appears to be a power issue and not a software one.

If anyone is really interested. The problem was resolved by using an external 6V power supply to
power the boards and an update of the LimeSuite library. Both changes were needed to get
rid of the Cannot Claim Interface messages. The LimeSuite update seems also to have fixed
other problems (setting/reading LPF values).
