Re: [SOLVED] Re: writing iso file to usb stick with dd - garbled files - usb eject error?

Hi,

a late comment to the failure messages about the USB stick in the
system log:

> [40799.447110] sd 7:0:0:0: [sdf] Attached SCSI removable disk
> [41167.136643] usb 2-1.2: reset high-speed USB device number 27 using
> xhci_hcd

The reset message is not caused by unplugging of the USB device.
I know it from failing USB boxes with optical drives.
Sometimes the USB-SATA bridge was to blame, sometimes the power supply
of the box was the cause. (I cross-swapped drives and power dumplings
in order to find culprit. New hardware fixed the problems.)
Most times it happened while using the drive. But a bad USB-SATA bridge
once caused such resets every few minutes with an idle drive.
(My USB boxes last about 5 to 10 years. Drives rather 15 to 20 years.)

Unplugging usually causes this kind of message:
> [41480.585883] usb 2-1.2: USB disconnect, device number 28


Have a nice day :)
