I just bought an usb-serial converter from Hama. If I plug it into my NetBSD 4.0/i386 the device is recognized by the kernel: Jan 28 13:51:14 hobbes /netbsd: uplcom0 at uhub0 port 2 Jan 28 13:51:14 hobbes /netbsd: Jan 28 13:51:14 hobbes /netbsd: uplcom0: Prolific Technology Inc. USB-Serial Controller D, rev 1.10/4.00, addr 3 Jan 28 13:51:14 hobbes /netbsd: ucom0 at uplcom0 However, when I try to use it I just can't send any data (a gps device). I hate it to say, it works flawlessly with Win, so the adapter itself is working. usbdevs -v shows: usbdevs -v: port 2 addr 3: full speed, power 100 mA, config 1, USB-Serial Controller D(0x2303), Prolific Technology Inc.(0x067b), rev 4.00 There seem to be some issues with the different revisions of the device. I found some posts with 2.02 - 3.0 and 4.0 - however as my knowledge in this field is quite limited, I am looking for help. Linux has some fixes (http://www.monkey.org/openbsd/archive/misc/0410/msg01202.html) for the driver to deal with the different revisions. Could someone give me hint what to fix in order to this one working? Regards Uli
