USB Drive not detected

Since update to El Capitan I have troubles with attaching a USB Drive (3.0) that works

in Yosemite very very we'll - within any anomalies.

I have to unplug and plug again , sometimes again , thats working.

I see some error messages :

It seems to be not a hardware problem, I see the problem in the El Capitan OS.
