Curiously, they identify as |067b:2303 Prolific Technology| like a common USB-Serial dongle brand. Experiments with blazer and nutdrv-qx got no reasonable response from the devices.

The cure Jim, is eliminate the prolific by replacing it with a FTDI dongle. Prolific has a bug in its wakeup, throwing away the first byte rx'd. I threw mine into the out bin 2 decades ago. Was trying to use it to talk to a cm11a for a heyu interface. Failed miserably. Encourage owners to toss it and get the FTDI-usb<->serial which Just Works.
