Thanks for your reply. On the website of the external USB 3.0 adapter states that it supports various Linux kernels. So, I suppose that the kernel of Debian 13 could support it.
Do your guide steps lead to booting from USB 3.0 disk on the USB 3.0 adapter and having USB 3.0 speeds in general? Do they include: - kernel + initramfs on USB 2.0 and root filesystem on USB 3.0? or - kexec (boot minimal Linux on USB 2.0, then jump to USB 3.0 kernel)? You may tell me the details of your guide steps and I will see what I could try with that. Cheers.
