Hello,
This bug occurs with version 4.13.0-21 (unrecognized all my usb 3.0 keys but he sees usb keys 2), my system is more stable with version 4.10.0-42, there is no link with an update. I do not want to test the kernel v4.15-rc6. My motherboard has Intel components (chipset X99). The key I use the most is a : SanDisk Extreme 64GB USB 3.0 Flash Drive SDCZ80-064G With kernel 4.10.0-42 the beginning of write speed may be at 180 Mb / sec, after a moment the speed becomes that of usb 2 (30 Mb / sec) and the speed decreases to 8 Mb / sec after a moment. When I want to eject my key, I have to wait very very long because all the data has not been written It seems that USB 3 is not correctly implemented / managed. Excuse my for my bad english. Best regards and happy new year 2018 to you. 2018-01-02 18:41 GMT+01:00 Joseph Salisbury <joseph.salisb...@canonical.com> : > Did this issue start happening after an update/upgrade?
