If you boot the OS with the USB memory connected, the OS will not recognize the USB memory properly.
 
Hi there,

If you boot the OS with the USB memory connected, the OS will not recognize the USB memory properly.
Recognize correctly when physically reconnecting after OS startup.
I think it will occur with USB 3.0 USB memory (I tried Transcend JetFlash 730)

In the result of lsusb, I want to output "Transcend Information, Inc." as the value of "idVendor", but it is output as "Silicon Motion, Inc. - Taiwan (formerly Feiya Technology Corp.)".


A state in which the OS is started with USB Stick (Transcend JetFlash 730) connected.

Welcome to LQ.

I don't think the system cares, frankly, what the disk is called.

The problem as I see it is that it's not recognizing it as a usb disk, otherwise it would load the usb_storage module. Generally, usb disks being mounted at /boot makes them only writable by root, and root should be used as little as possible. Why not just pull it while you're booting?

Thanks for letting me know.

I'm sorry. I could not understand what you taught me.
Under the current setting, is it set to mount USB connected to / root at startup?




The direct problem is that this USB is SoftwareRAID, it does not recognize the USB memory (Transcend JetFlash) when booting, so it is very troublesome to reconnect the USB every boot.

I hope that the OS (CentOS 7) automatically recognizes it as a USB memory by leaving it connected at PC boot time.

I believe that the OS erroneously recognized USB memory (Transcend JetFlash) as "SM3267AB MEMORY BAR" for some reason.
I want to find out this cause.

Sorry for typo - only one hand here.

Leaving a usb disk inserted while you boot means that only root can write to them. I avoid that when I remember by pulling them out. I have this line in /etc/fstab
Code:
/dev/sdb1        /mnt/hd          auto              relatime,diratime,user,exec,dev,suid,nofail    0  0
which is probably overkill, but it works. The 'user' option lets my user mount it, so as my user I can type
'mount /mnt/hd' and it is mounted, and a user can write to it. If I run X with XFCE, it automagically gets mounted somewhere crazy (/run/media/<user>/) but I can still write as a user.

Does the HD get the same device name with or without a bootable USB stick inserted at boot? If they differ, you could be suffering some kind of device enumeration or driver load order problem that might be solved by changing a BIOS setting, rebuilding an initrd, or changing fstab to mount / by label or UUID.

I suppose It would be easier for us to suggest a course of action if you were to explain what you wanted to do with your device.

It was slightly confusing because you called it USB memory. I assume you are talking about a USB flash drive also known as a thumb drive. Technically it is solid state memory, but all operating systems (Linux/Unix,Mac,Windows) treat the device the same as a hard drive/disk drive/zip drive. Sorry to be nit picky, but memory implies ram. And yes, on Linux you can force a thumb drive to act as a swap space, it would be weird and I think it is unlikely that is what you are looking for.

Flash drives are typically used to transfer data between computers or are used as short term storage of data that in not critically important.

From what little you have said on the subject, I am assuming that you want to use the flash drive as some sort of additional hard drive space on your Linux computer. You can do this, but you should be aware that flash drives have a notoriously high failure rate. If you are willing to accept one failure every two to three years you may still pursue this path. Just have a plan on how you will deal with such a failure.

If you are not going to use the flash drive to transfer data to a non-Linux computer, I would suggest that you reformat your flash drive to ext2/ext3/ext4 and name the partition using tune2fs.

Please respond to the question so I can better help you.
