Just installed new eMMC Chip (bigger) with 16.04. Before I used 15.10. My USB3 drive was used every day. The new version does not find the drive. I remember, that 15.10 started with teh same problem, bus on the sudden it was detected.
I tried 3 different drives, one 2.5Inch with USB-power, 2 3.5Inch with own powersupply. Attached to USB2 the drives are found. I found following info
$ dmesg

USB3 chio must be ok as network is ok and with my HW-info it is attached to USB3. The last lines of dmesg ouitput above semm to confirm that. But what about the disk drive and the error info before the ehter lines?
BEsides: how do I supply system infos like above in the right way? Other forums have an option to include “code” lines.
Please excuse, but there are mor problems. I will post in separate topics.
