Hello, Thanks for your support, I don't know if the problem occur if the SSD is not connected as root partition and it will be difficult to test it as the internal SSD is windows7 type and I can't modify it (it's a professional laptop from my company). I will test with xhci debugging... Do I have to check the output of the debugging in journalctl or somewhere else? lesebas 2015-12-11 9:42 GMT+01:00 Mathias Nyman <mathias.nyman@xxxxxxxxxxxxxxx>: > On 10.12.2015 18:18, Sébastien Deligny wrote: >> >> Hello I've report a bug on bug tracker but I've been advise to post it >> directly to th mailing list.
