AFAIK, /dev/disk/by-id/ is not supported, use /dev/sdX where X is the appropriate identifier.

Yea, as @JonnyTech mentioned. Use /dev/sdX path.

AFAIK, /dev/disk/by-id/ is not supported, use /dev/sdX where X is the appropriate identifier.

In that case, perhaps it would make sense to print an error message to that effect?

The error you posted clearly states that the path you entered was not a storage device.

Indeed. Which seems misleading to me, since it is (a link to) a storage device.

To clarify, since I didn't mention it in the issue, /dev/disk/by-id/usb-Kanguru_FlashBlu_0702353730542E72-0:0 is a symlink to /dev/sdb.

IMHO, this tool should be used by power users who understand that one must write to a device identifier rather than a symbolic link.

Why would power users assume that this tool, unlike other tools for disk management, would be unable to support symlinks /dev/disk/by-id?

The author of the code already pointed you to the location in the source where it is stated.

What is the output of ls -la /dev/disk/by-id/? Does it have the -0:0 suffix at the end? I have not seen that format before. Can you try:

woeusb --device Win10.iso /dev/disk/by-id/usb-Kanguru_FlashBlu_0702353730542E72

To resolve the link, we can use readlink -f /dev/disk/by-id/foobar - @WaxyMocha dou you want to include that step?

This tool is behaving this way because the check for the device have so shaky assumptions about how the path to block device should look like.
https://github.com/WoeUSB/WoeUSB-ng/blob/master/WoeUSB/utils.py#L95

Yes, your way should work, but it is not supported.
@kevinoid do you have need for specifying device like this, or are you just reporting to us that software is just not behaving as expected? Either way, I'm sorry, but I currently lack time to do any changes to the codebase.

@kevinoid can you try:

woeusb --device Win10.iso /dev/disk/by-id/usb-Kanguru_FlashBlu_0702353730542E72-0\:0

and

woeusb --device Win10.iso `readlink -f /dev/disk/by-id/usb-Kanguru_FlashBlu_0702353730542E72-0\:0`

(the first escapes the colon -0\:0 and the other resolves the symlink too)

Thanks @WaxyMocha!

@kevinoid do you have need for specifying device like this, or are you just reporting to us that software is just not behaving as expected?

I did try to use the device in the example. I find that using /dev/disk/by-id/ reduces the chance of operating on the wrong device (since sdb, sdc, etc. change while by-id is stable). However, I'm capable of working around it, so there's no hurry to fix it for my benefit. I reported the issue because I thought it might be something this project would be interested in supporting. Feel free to prioritize, or close, as appropriate.
