I have an headless system running Ubuntu 14, with a xtion pro live camera connected to do some live video elaboration.
Sometimes on boot (every morning is power on, but this is happening ramdomly) the camera is not recognized and dmesg shows:
usb 1-2: device descriptor read/8, error -110
usb usb1-port2: unable to enumerate USB device
The camera is not even listed in lsusb.
What I tried without any success is:
- Computer reboot
https://davidjb.com/blog/2012/06/restartreset-usb-in-ubuntu-12-04-without-rebooting/ (usb device it's not listed in lsusb)- https://askubuntu.com/a/661/373541
- on BIOS fast boot is disabled
- can't rmmod/modprobe xhci_hcd as it's builtin
- https://github.com/mvp/uhubctl
The only working solution is to poweroff/poweron the computer (not feasible as is an headless system, it poweroff every night, and poweron every morning but I'd avoid waiting next day when the problem occurs).
Is there any solution to simulate the physical disconnection of the device (I not even sure if this would work) or the poweroff for what USB concerns?
Any ideas will be appreciated, thank you.

Tryuhubctl -R -a cycle. But it will work only if your hub supports per port power switching (to be recognized by uhubctl).

@rok: did you try with-R? Adding-Rwill try to use appropriate USB reset mechanism supported by your OS (Linux in this case).
