Good Day,
I am running FreeBSD 4.9-RC3 and have problems attaching
a couple of Belkin USB serial adaptors to the machine.
The kernel has been configured with all drivers necessary:
options USB_DEBUG
device uhci # UHCI PCI->USB interface
device ohci # OHCI PCI->USB interface
device usb # USB Bus (required)
device ugen # Generic
device uhid # "Human Interface Devices"
device ukbd # Keyboard
device ulpt # Printer
device umass # Disks/Mass storage - Requires scbus
and da
device ums # Mouse
device uscanner # Scanners
device urio # Diamond Rio MP3 Player
device ubsa
device ufm
device umodem
device ucom
device uplcom
device uvscom
device uvisor
device uftdi
During boot the 4-port USB hub and the three devices are
recognized properly:
uhub1: Genesys Logic USB Hub, class 9/0, rev 1.01/0.12, addr 2
uhub1: 4 ports with 4 removable, self powered
ubsa0: Belkin Components USB-232 Adapter, rev 1.10/2.08, addr 3
ubsa1: Belkin Components USB-232 Adapter, rev 1.10/2.08, addr 4
ubsa2: Belkin Components USB-232 Adapter, rev 1.10/2.08, addr 5
When attaching one adaptor after boot, ubsa is loaded:
Oct 29 17:27:48 router /kernel: usbd_new_device bus=0xc1e33000 port=1
depth=2 lowspeed=0
Oct 29 17:27:48 router /kernel: usbd_new_device: adding unit addr=3,
rev=110, class=0, subclass=0, protocol=0, maxpacket=8, len=18, ls=0
Oct 29 17:27:48 router /kernel: usbd_new_device: new dev (addr 3),
dev=0xc1e34280, parent=0xc1e34480
Oct 29 17:27:48 router /kernel: usbd_probe_and_attach: trying device
specific drivers
Oct 29 17:27:48 router /kernel: ubsa0: Belkin Components USB-232
Adapter, rev 1.10/2.08, addr 3
Oct 29 17:27:48 router /kernel: usbd_set_config_index: (addr 3)
attr=0xa0, selfpowered=0, power=100
Oct 29 17:27:48 router /kernel: usbd_set_config_index: set config 1
Oct 29 17:27:48 router /kernel: ucom_attach: tty_attach tp = 0xc20ccb00
Oct 29 17:27:48 router /kernel: ucom_attach: make_dev: ucom0
But the device cannot be used. /dev/ucom0 (and ucom1, ucom2) will
not be created even tough make_dev is called.
Manually creating them via ./MAKEDEV doesn't work either:
root@ws02 /dev # cu -l /dev/ucom0
cu: open (/dev/ucom0): Device not configured
cu: /dev/ucom0: Line in use
root@ws02 /dev # echo xyz > /dev/ucom0
-bash: /dev/ucom0: Device not configured
Am I missing something?
Thank you!
Best Regards,
Markus

I do not have -stable with ubsa device handy for testing, but I do use
one ubsa adapter for my serial console for 5.x daily. Errors below
certainly indicate the device entry mismatch. The quick and dirty
solution to try would be a printf right after ubsa/ucom calls makedev on
udev device to print out device's major/minor address and using mknod
manually.
