hi,
this usb device (actually the micro usb on a esp32c3) is reported by FreeBSD 12.1 as:
ugen0.10: <vendor 0x1a86 USB Single Serial> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (134mA)

and dimes shows:

Nov 28 19:02:19 pampa kernel: ugen0.10: <vendor 0x1a86 USB Single Serial> at usbus0
Nov 28 19:02:19 pampa kernel: umodem0 on uhub3
Nov 28 19:02:19 pampa kernel: umodem0: <vendor 0x1a86 USB Single Serial, class 2/0, rev 1.10/4.43, addr 16> on usbus0
Nov 28 19:02:19 pampa kernel: umodem0: data interface 1, has no CM over data, has no break

it’s the last line that I think is causing failure to flash the device (probably needs the break to set the speed?)

any ways, is there some fix for this?

thanks,
	danny
