Hello! Sorry if off-topic. It isn't a bugreport. It is a request for help to write a bug report. Recently I've upgraded my PC from Biostar TF560 A2+ to MSI 760GM-P21(FX) (MS-7641) and found USB flash drives not working. `lsusb` output is just fine, `dmesg` repeats "usb 2-5: reset high-speed USB device number 3 using ehci-pci". The issue reproduces at openSUSE 13.2 (desktop-3.16), Leap 42.1 (vanilla- & default-4.1) & TW (default-4.7) but it can't be reproduced at openSUSE 13.1 (desktop-3.12) & Kubuntu 16.04.01 (4.4). STR: openSUSE, kernel ≥ 3.16, MSI 760GM-P21(FX) (MS-7641), any USB flash drive. Expected result: /dev/sdxN, mounting etc. Actual result: sometimes there are no /dev/sdxN only /dev/sdx is present, sometimes /dev/sdxN is present but can't be mounted with timeout error, sometimes it can be mounted but file operations (`ls`) take minutes. `dmidecode` output is attached. Anu help is welcomed! -- Best regards, Dmitriy Perlow R&D chemical engineer Lekpharm JLLC
