Box: Pogoplug V4
Kernel 4.8 with kernel 4.6 DTB

Problem: After reboot (shutdown -r now), Can not see usb device.
-- It didn't happen every time. But it happened most of the time.

But if shutdown and turn the power off, then turn it on, the device may come back.

If this is a USB hard drive then it is a common issue.

If you have serial console or net console, reboot, interrupt console and,

ver
printenv
usb start
boot

and post the entire log here.

Yes, it is a USB hard drive.
Thank you for your help. I'll try the net console tomorrow.

Hi bodhi,
Sorry for report late.
These two days, I have done reboot for nearly 20 times, but only 1 time, It couldn't find the usb device, and just at the same time, the sd card corrupted.
I'm confused, because the day before, it lost usb device almost every time.

That's OK.

The u-boot envs determine the boot sequence, if envs are set up correctly then no worry. So when you lost the USB device, but able to boot SD card, then post the log of that session.

Usually, some USB HDD has problem "spinning" up. And when that occurs, in u-boot console you can see the error

"EHCI timed out on TD - token=...."
