Hi Arnaud, Unfortunately your patch didn't solved the problem for me. I googled about the issue once more while setting the OS second time to give logs you asked previously. Out of the syslog you can see that it is being flooded with *usbfs *errors about claiming the device. One of the suggestions was the problem with *dwc_otg *driver. However my solution was a script, which resets usb and I'm able to get data from UPS again.. As I mentioned above that re-plugging the usb cable solved it. Problem is not stable ~3 fails out of 5 startups. At the moment I am using PW5115
