...evice is a Sprint PC5740 pc card. When I perform a "man umodem" the card is listed (vendor = Curitel) UMODEM(4) FreeBSD Kernel Interfaces Manual UMODEM(4) NAME umodem -- USB modem support SYNOPSIS device umodem device ucom DESCRIPTION The umodem driver provides support for USB modems in the Communication Device Class using the Abstract Control Model. ... The device is accessed through the ucom(4) driver which makes it behave like a tty(4). HARDWARE Devic...

I'm trying to make devd run an stty command whenever a USB serial device is attached. Unfortunately, $device-name is ucom[0-9] and the device names are /dev/cuaU[0-9] - how do I get the correct name in the device action? I haven't found a way to extract the number by itself, so I'm stuck with specifying a separate rule for each number, like so: attach 100 { device-name "ucom0"; acti...

Hi, I've noticed some general instability with plugging in or removing USB devices with FreeBSD 7.x, even when the devices are not actively in use. I had this happen with umass and ucom devices 3 times today. The machine hangs solid, there are no obvious signs of a panic or trap to DDB. I can't provide backtraces unfortunately -- these hangs happen on both my laptop and desktop, and I usually have X running -- if I had more specific information, I'd open a PR. Again,...

...ol the FreeBSD side of things and the other end of the serial connection is a windows app we dont control. Everything seems to work ok from our side, but the other side which we dont control seems to be missing some things we are sending it and vice versa. I also tested the application with a ucom attached driver and it also does not work so I suspect something our app is doing. However, if I use something like minicom or cu, I see 2 way communication just fine and I can transfer data back and forth just fine. Is it possible some defaults are different from sio to uart that our app mi...

Hi All, I'm running stable from August 19/2003. I've got a few A7N8X-Deluxe boards. One Rev1.0 and two Rev2.0. While the 1.0 board works, the 2.0 boards lock up on boot during the uhub0 bus discovery. It's extremely frustrating :) ... While I can boot without the devices and attach them later, the devices ( logitech usb keyboard, logitech mouse, rio800, samsung CDMA adapter,
