The system gets stuck when a specific USB device is connected.

Matthew Wai · 03-09-2023, 02:37 AM

I have a USB 2.0 Kingston device. If it is connected to my PC, when I start UnionTech OS, the OS will get stuck for about one minute after the startup, and whenever I connect another USB storage device, the OS will get stuck again for about one minute. The problem only arises on UnionTech OS and never arises on Windows 10 and Linux Mint installed on the same PC. The problem is caused only by the said device but not by any other USB device. I have reformatted the USB device, but the problem persists. I checked the device with "fsck", which found no problems. See the output below:

Code:

Matthew_Wai@My-PC:~$ sudo parted /dev/sdd 'print'
[sudo] password for Matthew_Wai:

Matthew_Wai@My-PC:~$ sudo fsck /dev/sdd1

fsck.fat 4.1+git (2017-01-24)

How can I find what is wrong with the USB device?

I don't know this UnionTech OS, but I would definitely check logs like dmesg, kernel log and similar.

you need to check what's happened during that 1 min, when the system was stuck.
