Hello!

I'm using FreeBSD 12.2-STABLE r368656 and got usb-to-rs232 with this
controller.
I see /dev/cuaU0 after plugging in adapter, I can attach to serial line
using cu, but after sending any symbol to device I have device reconnection:
uchcom0 on uhub0
uchcom0: <vendor 0x1a86 USB2.0-Ser, rev 1.10/2.54, addr 17> on usbus0
uchcom0: CH340 detected
uchcom0: at uhub0, port 9, addr 17 (disconnected)
uchcom0: detached
uchcom0 on uhub0
uchcom0: <vendor 0x1a86 USB2.0-Ser, rev 1.10/2.54, addr 17> on usbus0
uchcom0: CH340 detected
