I have tried searching the group.io archive and got nowhere. Hopefully this is a new problem, and I didn't just miss it.

I flashed this H4 just over 2 years ago (Feb 2023) to version 1.2.19 using this same hardware but a then-current version of Debian Linux. Now I'm using a newer Debian version (Bookworm), and cannot connect to the Nano in any mode, scanning or DFU.

"new full-speed USB device number XX using xhci_hcd"
"Device not responding to setup address."
"device not accepting address XX, error -71"

"XX" increments at every attempt to connect.

The only difference I can find in my notes from 2 years ago is the kernel module is no longer "uhci_hcd," and is instead "xhci_hcd." Has the Linux community "upgraded" me beyond the ability to flash this thing? Am I needing to get the serial port dongle and some grabber clip leads?

Linux probably thinks the device is pulling too much power. I'd ensure
that the battery is fully charged.

Nah, not even remotely a possibility. One of the three machines is a server-class box that doesn't have a battery (other than the CMOS backup cell).

Kind of got it down to changes in the kernel module, xhci from uhci. Might be wrong but that's where the debug is pointing.
