Hi peeps,
On my AMD64 box running freebsd 6.3 I have a lot of trouble with my usb ports lately. I have attached a samsung ml-1610 printer to one usb port, but I do experience the same when I plug in a usb stick (kingston data traveller).
Take a look at what dmesg says:
module_register_init: MOD_LOAD (logo_saver, 0xffffffffb4ecf3d0, 0) error 19

Fact is, both periphals were never removed out of the usb connectors. This means I sometimes can print and sometimes not. Then when I reboot, all of a sudden al my "forgotten" print commands do get executed. I don't know what happened with the usb support on freebsd but I know it got worse. A year ago I could use the usb stick without any problem.
uname -a
FreeBSD amd_desktop.telfort.nl 6.3-RELEASE-p4 FreeBSD 6.3-RELEASE-p4 #21: Wed Oct 1 08:07:27 CEST 2008 rgilaard at amd_desktop:/usr/obj/usr/src/sys/MYKERNEL amd64
In MYKERNEL the us part shows:

What seems to be the problem here? What can I do to solve it?
Thanks in advanced,
Dino
