Description kazarov 2001-01-04 14:30:00 UTC

This is a SMP system with 2 Celeron-466. 
ZyXEL Omni 56K Plus modem plugged into the USB port.
System correctly detects modem but on after disconnection and reconnection disables port.

ugen0: at uhub0 port 1 (addr 2) disconnected
ugen0: detached
uhub0: device problem, disabling port 1
uhub0: device problem, disabling port 1

I've tried also to connect HP scanner and Creative USB camera with similar behaviour: system correctly recognize device on startup but disables port on reconnection. All devices work correctly on MS Windows ME.

This looks like it should be looked at by me, I think.

Comment 2 kazarov 2001-01-08 09:53:56 UTC

When I load a kernel without SMP support (the same config with SMP and
APIC_IO lines commented out) USB works correctly - it detects detachment and
reattachment of devices without andy delay while in SMP mode there was a
delay about 10-20 sec on detachment and before disabling port after
reattachment.
BTW, system does not sees second USB port - neither with SMP nor without
SMP. Windows works with both ports the same way.

Comment 3 kazarov 2001-01-09 13:54:03 UTC

I've solved the problem with second port - signal lines were shortcuted
(probably I did not tryed it under Windows). Now both ports work correctly
but only without SMP.

Is this still a problem with modern versions of FreeBSD?
