D415 Device Recognized on Power Up, Not on Reboot

Required Info
Camera Model	D415
Firmware Version	05.08.15.00
Operating System & Version	Ubuntu 16.04.4 LTS
Kernel Version (Linux Only)	4.4.0-116-generic #140-Ubuntu SMP Mon Feb 12 21:23:04 UTC 2018
Platform	NUC with dual Intel(R) Core(TM) i5-6260U CPU @ 1.80GHz cores
SDK Version	librealsense tag 2.10.0

Issue Description

When rebooting this type of NUC computer with a D415 plugged in, the D415 does not register properly as a USB device, with the following error in dmesg output. However, when it is power cycled, the D415 registers fine.

[ 2.477775] usb 2-4: device not accepting address 2, error -71

I've attached the USB relevant bits of dmesg and the output of lsusb -t from a good start on power up, and from a bad start on reboot. Oddly enough, this does not occur with newer NUC models with dual Intel(R) Core(TM) i5-7260U CPU @ 2.20GHz cores, where the device registers fine on reboots.

Looks like dmesg output on failure didn't upload correctly. Here it is again.

@jallard-sr, in the BIOS settings try setting the xHCI mode to Enabled (not Auto or Smart Auto) under Devices/USB.

This setting was already enabled in the BIOS as described: xHCI mode = Enabled From: RealSense Customer Engineering [mailto:notifications@github.com] Sent: Monday, March 12, 2018 5:28 PM To: IntelRealSense/librealsense Cc: Subscribed Subject: Re: [IntelRealSense/librealsense] D415 Device Recognized on Power Up, Not on Reboot (#1283) [Realsense Customer Engineering Team Comment] @jallard-sr<https://github.com/jallard-sr>, in the BIOS settings try setting the xHCI mode to Enabled (not Auto or Smart Auto) under Devices/USB. — You are receiving this because you are subscribed to this thread.

Although I haven't seen this with the 415 it is similar to an issue with the 435 - except xHCl mode = enabled was a usable work-around (newer NUCs only have xHCI). For the f/w 5.9.2.0 fixed the problem for the 435 cameras so you can try that if you wish. https://downloadcenter.intel.com/download/27522/Latest-Firmware-for-Intel-RealSense-D400-Product-Family?v=t

@jallard-sr did you try 5.9.2.0 f/w and/or do you still see the issue?

@jallard-sr I assume that you are no longer having this issue and I will close this ticket. If you still have this or any other problem please feel free to open another issue.

Thanks.
