Which hardware gives 4 serial ports from 1 USB? I'm quite happy with products from Vcsom: http://www.vscom.de/1_1_09.htm But I'm sure there are many other products available.

Please take a look at ftp://ftp.z74.net/pub/OpenBSD/ if anyone is interessted. You can use these files to do a normal install or upgrade. Of course, it's up to you to decide whether you trust me.

This fits the spec. I'd say it doesn't. 1000 mA at 12 V is only 12 VA. You need a bit more to be able to deliver 15 VA. I think 12 VA should be enough in most cases, but you might need more than 12 VA if you have some extras in the case. >The unit that hung was running on the 750mA >supply.

I've been using the GENERIC kernel with a 4501 and a 4801 without any problem. It's possible that there are some advantages by using a custom kernel that I'm unaware of, but I never felt the need to try.

You need something more than just that. Something needs to tell the modem to go off hook when a call comes in. I've been using mgetty for this and I'm quite happy with it.

Perhaps the GND levels of the DWL-P50's is different when set to 5 or 12 Volt output? That would cause a short-circuit current that destroys the USB port. You can measure the voltage between GND of two adapaters without the Soekris and USB hub connected. If you measure (very close to) 0 V between both GND outputs, you can't use them like this.
