sometimes, I can’t see my usb_to_sata hdd/sdd storages after rebooting system.

Could you tell me how to resolve this issue?

I found some threads in forum.

  1. Share the full dmesg when error happened and not happened instead of a photo of your connection… it really does not matter to us how your board “looks like”…

  2. Try new jetpack release as usb firmware may have update.

I’ll suggest a full serial console boot log and not just dmesg log, with one log when it works, and one when it fails. In a working case I’ll also suggest showing the output of “lsblk -f”. Also, a working-versus-non-working “lsusb” and “lsusb -t”.

Hello,

  1. Share the full dmesg when error happened

Thank you.

Do you have any suggestions for the dmesg attached above?

Thank you.

I saw some usb device returns -71 error. Could you check if that is your usb to sata device? And it is only in full speed.

Hello, @WayneWWW

Could you check if that is your usb to sata device?
=> Yes.

And it is only in full speed.
=> Are you saying that usb to sata only supports full speed?

Thank you.

No, I am asking you question…

I don’t have your board or your device so I want to ask you if this is normal to see it is in only full speed mode…

Try to upgrade your jetpack version. Maybe new usb firmware can help.
