You might take power consumption into acount. If your hub is not powered it can't supply more then 100mA per port. check the required consumption of your ethernet devices with usbdevs -v. In case they require more then 100mA you *must* use a self powered hub. Many cheap hub lie about their power state, but that doesn't change the requirements at all. -- B.Walter BWCThttp://www.bwct.de [EMAIL PROTECTED] [EMAIL PROTECTED] ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

It looks like I need to try a powered hub: laptop# usbdevs -v Controller /dev/usb0: addr 1: full speed, self powered, config 1, UHCI root hub(0x), Intel(0x), rev 1.00 port 1 addr 2: full speed, power 300 mA, config 1, USB 2.0 Ethernet adapter(0x1040), BayNETGEAR(0x0846), rev 0.01 port 2 powered I'll scrounge up a powered one and report back.

so easy. However, the laptop only has one usb port. So, I
picked up a cheap 4 port hub so I could connect my two adapters
(both netgear FA120 devices).
The boot log shows that both devices are recognized. However,
only one gets configured properly (it gets an address and
actually works). The other adapter can't be configured (at
boot time or on the command line). This is whether the devices
are plugged in before booting or after. If I try to remove
either of them after booting I usually get a kernel panic and
a reboot.
Am I trying to do something that can't be done (do I need two
physical ports on the machine for this to work)? Is this
merely a bug in 5.1 that would be fixed if I go to 'CURRENT'?
Does anyone have any comments? For completeness I'm appending
the relevant lines from my config.
Any help would be appreciated.
There is definitely one problem that stops you from using two
identical USB ethernet devices, but I don't know if it's the only
one: the axe driver uses a static (global) stucture for some
per-interface data, so it clobbers this state with two interfaces.
I had said to Bill Paul (cc'd) that I would suggest a patch to fix
