AutoPlay does not work when a USB flash drive plugged in a specific port

y123k — Fri, 17 Feb 2023 03:05:45 +0000

AutoPlay does not work when a USB flash drive plugged in a specific port, and the USB icon does not appear in the notification area on the taskbar (files can be accessed without problems).

Module: UPC-PLUSX5D-A20-0232
OS: Windows 10 IoT Enterprise 2021 LTSC
USB port: USB2_DP5/USB2_DN5 signal on pin86/pin88 of the DOCKINGII (CN12) connector to the USB connector on the custom carrier board.

There are no problems with the other USB ports (ports on the UCP module and USB2_DP3/USB2_DN3).

Is there any difference between the USB2_DP5/USB2_DN5 and any of the other usb ports ?

Screen Resolution on Ubuntu 20.04.5 limited to 1024x768

Hello Up-Community,

I just set up my Up Core Plus (8GB, 64GB, E3950) with Ubuntu 20.04.5 according to the instructions from https://github.com/up-board/up-community/wiki/Ubuntu_20.04. The installation with the new kernel 5.4.0 went smoothly. The only problem is that the selectable screen resolutions are now limited to 800x600 and 1024x768. What can I do to be able to select Full Hd? I thank you in advance for all your efforts. To all who read this, have a nice day!
Best wishes
Sigurt

[Core Plus+Vision Plus X] dmesg errors: "usb 2-5: Failed to suspend device, error -19"

Hi UP Community,

I have installed Ubuntu Server 20.04 on a new UP Core Plus board with an UP Vision Plus X, following these Ubuntu 20.04 intallation instructions

Everything seems to be functionally working, and I can run the .../deployment_tools/demo/demo_benchmark_app.sh with and without the -d MYRIAD flag and get ~230 and ~45 fps throughput respectively. (I don't know what to expect, but seems good).

However, my dmesg log is completely littered with the messages:

...
[   14.577868] usb 2-5: new SuperSpeed Gen 1 USB device number 75 using xhci_hcd
[   14.602845] usb 2-5: New USB device found, idVendor=05e3, idProduct=0620, bcdDevice=93.03
[   14.602851] usb 2-5: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[   14.602855] usb 2-5: Product: USB3.1 Hub
[   14.602858] usb 2-5: Manufacturer: GenesysLogic
[   14.604704] hub 2-5:1.0: USB hub found
[   14.605228] hub 2-5:1.0: 4 ports detected
[   14.885670] usb 2-5: USB disconnect, device number 75
[   14.885695] usb 2-5: Failed to suspend device, error -19
...

The errors occur seemingly at random, sometimes they trickle in at about one per second, sometimes I see a rush of several hundreds of them over several minutes, and sometimes they don't occur for hours.

Apart from at least one such error always occurring at boot, I can't see any pattern. It seems neither related to workload nor whether I have used the MYRIAD devices or not.
I also saw the errors already before I updated the kernel.

I tried to reinstall the OS, and switched to another power source (12V, 2A), but the errors occurs (... but possibly to a somewhat lesser extent).

Is this normal, or is there a known fix, or may I have defective hardware?
I don't want to evaluate the merits of this hardware based on a faulty unit.

Maybe unrelated, but twice (in the first couple of days) the system also froze completely, and would not respond to ping let alone ssh, and I had to power-cycle.
I haven't had a freeze since I re-installed the OS (~24 hours), but I still suspect it might be related to the usb error.
If the hardware is freezing occasionally, it would mean a no-go for this hardware on my projects.

Very thankful for any help on this.

Best Regards,
Anders Astrom

Just one USB device

I received my Core Plus but i have the problem (well i think it is one) that i can not connect more than one device to the USB port.

I tried a USB Hub with and without extra power supply
I tried to use the Micro-B but also no function
I tried an ethernet USB adapter to use PXE also no function
I tried different BIOS settings but nothing seems to change anything

Am i do something completely wrong or is my device broken?

I plugged video and power in and nothing

I plugged video, power and usb 3 hub in and connected keyboard and mouse. when I hit the power button I get nothing. I would like to install Linux Mint or Debian on this. help

On delivery: No boot. Next steps?

This is a copy from post to question from 'scottie4442: I plugged video and power in and nothing'. As no answer/steps were posted I'll post it again as a separate discussion.

Does anybody else have same issues?

I waited several months to receive the Up Core Plus from Kickstarter and on the first try I just get a blue LED lighting and no other sign of life. (Connected the power supply as delivered alongside with the Up board and attached a display to the DP - pressing the power button shortly or longer does not help) At least I was expecting to see a kind of BIOS boot image or text, but nothing. Furthermore, is there any How-To or Wiki for the Core Plus? Can't find anything related or specific for the Plus, only for the 'old' Up Core... I also tried to remove and reattach the coin cell battery as suggested for the Up Core, but also without help, still same behavior.
Am I still missing something?

Would appreciate any pointers to debug/triage the issue. And please update the Wiki for Core Plus as well. Looks like I'm not the only one having such an issue (check post from scottie4442). Thanks
