USBasp no longer works with FreeBSD 14.1 / avrdude 7.3

Hi,

Once a year, I flash some ATtinys.
For ATtin861, i use USBasp from https://www.fischl.de/usbasp/ .
USBasp worked fine with FreeBSD 13.2 / avrdude 7.0 [1]
Now after upgrading the OS and avrdude, it fails:
- - -
usbd_set_config_index: could not read device status: USB_ERR_STALLED
ugen0.2: <ERFOS AVR-ISP2> at usbus0
umodem0 on uhub0
umodem0: <ERFOS AVR-ISP2, class 2/0, rev 2.00/43.40, addr 22> on usbus0
umodem0: data interface 1, has no CM over data, has break
ugen0.2: <ERFOS AVR-ISP2> at usbus0 (disconnected)
umodem0: at uhub0, port 5, addr 22 (disconnected)
umodem0: detached
- - -

Any tips welcome,
Axel
