I recently acquired a Jetson Orin Nano Developer Kit and hit a number of problems with setting it up using the SDK Manager.
My first attempts were using a Virtual Machine under Proxmox/QEMU with Ubuntu 20.04 and 18.04 installed, each failed to flash the Nano due to USB error.

There must be something about the USB pass through from the physical Host to the Virtual Machine that the sdkmanager does not like.
The above issue goes unsolved, but have added it here in case others come up against this problem.
I ended up flashing the Nano successfully using a Laptop running Ubuntu 20.04 on the physical host.
