Use LimeSuite and LimeSDR-USB to run LTE eNB in Ubuntu 18.04.
After 2 hours the LimeSuite keep printing USB TRANSFER ERROR in loop. Restart the LTE eNB the issue still happen. Only after reboot Ubuntu it is working again.
This issue is reproducible with in 5 hours.
I tested with 2 different types of PC (totally different hardware configuration ) the same issue happened.

The error indicates that there is something wrong with USB communication. If your PC have multiple USB controllers (e.g. 3.0 and 3.1) you can try using different port. I remember seeing this problem on one PC when using USB 3.1 port but it was fine on USB 3.0 (different controller).
Pressing FX3 reset button on LimeSDR-USB or re-plugging It, should cause the device to re-enumerate. I think it may also make it work again. In such case you can also try to search for a way to reset USB device from OS.
