avrdude: usbdev_open(): did not find any USB device "usb" (0x03eb:0x2104)

Looking at
usbdev_open, I see:

(lldb) p/x pinfo
(pinfo) $1 = {
  baud = 0x00000000210403eb
  usbinfo = (vid = 0x03eb, pid = 0x2104, flags = 0x0000)

usbdev_open is called from stk500v2_open, where I see:

   pinfo.usbinfo.vid = USB_VENDOR_ATMEL;
    pinfo.usbinfo.pid = USB_DEVICE_AVRISPMKII;

This seems to be hard wired for all stk500v2 devices, ignoring my configured usbvid and usbpid.

I can't find a configuration, which allows me to use this device.

It's not such simple. Simply patching USB_VENDOR_ATMEL and USB_DEVICE_AVRISPMKII is not enough:

ATMEL-Studio 7: Tools->Add target->Select Tool: STK500, Select serial port: COM...

Judging by their description, the programmer implements a virtual serial port. In that case you do not specify the USB vid:pid, but the serial device via the -P option. Meaning you do not need a config, but just use -c stk500v2. Also, they claim to implement STK500, not STK500v2.

avrdude is running in a jail on FreeBSD 13.0-STABLE.

I have tried to get the serial communication to work with help of some people from the freebsd-hardware list without success. I always get timeouts.
Without the -i option, I do not get any results. With -i, I see this:

avrdude done. Thank you.

The cuaU device also does not show any results.
I'm out of ideas.

The command-line syntax you use looks about right. What does the manual/vendor say about how to connect to the programmer?

avrdude is running in a jail on FreeBSD 13.0-STABLE

I suppose there is potential for problems. Perhaps you explicitly need to set some permissions? @dl8dtl ?

There is no manual. Just one page to download:
EN: Description
Or 2 pages in German, which give more details (e.g. adaptive SPI-bitrate adaption):
DE: Bedienungsanleitung:
The target is on a ZIF socket and I have both switches turned on, so the programmer provides 5V to the target.
Unlike written in the German description, the green LED does not stay on after plugging in the programmer.
I'm waiting for email response from the vendor.

I created the necessary devfs rules, I'm running avrdude as root and, as you can see in the log, the programmer can talk to the cuau0 device.

Hans Petter Selasky hps@selasky.org found cause and work around:

I see from the Ellisys .png's what is wrong. The device doesn't support
resetting the data-toogle (CLEAR ENDPOINT HALT) which is a mandatory USB
control endpoint command. So the USB stack tries a couple of times and then
gives up and resets the device!

The device is not USB.org class compliant! :-(

Probably setting:

sysctl hw.usb.no_cs_fail=1

may help.

Indeed, it solved the issue.
Vender announced a new device with compliance.
