I don't know if this will help.
I know somewhere on these forums, probably in more than one place, there is mention of the 2.6 kernel setups playing a stricter role of monitoring USB power at the USB port. This was mentioned quite some time ago in Open Zaurus, and some people were having trouble with USB dongles that just worked in the older 2.4 kernel.
I just hooked up my Belkin - F5D5050 USB 1.1 10/100 Ethernet Adapter to my router and my C3200.
In pdaxii13, I need to open the "Lan and WiFi" app and make the connection.
I'm online with it now.
Below is dmesg output from the first usb entry.
Note: Look at the last 3 or 4 lines. This is where my dongle actually shows as being used.
