I have a Prolific USB-Serial Controller which works on some USB ports
with tip, but, not others.
This is on a HP dv6000 laptop running up-to-date 6.2-stable with a
custom kernel. This included all the devices found by GENERIC plus
ucom and uftpi. I need to add uplcom, but, for now, I kldload it.
I have included the output from "usbdevs -v" and the usb part of
dmesg.
If I use a port on the expansion tray, usb4, I sometines get
uplcom_set_line_coding: IOERROR
But, if I use a port on the laptop, usb0 or usb1, it works.
I have a Prologix USB-GPIB adapter which works with
open("/dev/cuaUx",O_RDWR | O_NOCTTY | O_NONBLOCK))
on either set of ports.
If I connect the USB-Serial Controller to usb4, it does not work. If
I connect it to usb0 or usb1 it works. I can not identify usb2 and usb3.
The only differences I see is multiple translations to usb4.
Any ideas?
