Tested with Debian from SD, but should work in Angstrom with some work. The ipheth wwan0 device only provides a connection over the 3G modem, even if you're connected to a wifi network. I used the iproxy and SSH tunneling method with proxychains to get to the wifi network.

Apple USB Ethernet Adapter MB442Z/A	Not required	standard-A	USB 2.0		standard-A port	Yes	Yes	Works perfectly on the Pandora. You may need to left-click the networking icon on the panel in Xfce, and click "Ifupdown (bnep0)" in order to connect to the internet.

Belkin Gigabit USB 2.0 Network Adapter	Not required	standard-A	USB 2.0		standard-A port	Yes	Yes	Works fine, the shape of it make is a bit awkward to fit if you connect it directly, but it has a short adapter cable. I only get ~95Mbit on a gigabit network, but then the pandora's cpu maxes out. (it may be that the driver/usb stack isn't very well optermised), has horribly bright blue led's.

USB WiFi adapters

The Pandora stock kernel doesn't seem to come with any wireless driver support outside of the internal wifi chip. The only way you'll get wireless working is to build your own kernel with it included or try compat-wireless.

Belkin N1 Wireless USB Adapter (F5D8051) ("Ver. 2053") (MARVELL v1021)	N/A	Standard-A	USB 2.0		Not connecting it at all.	Reported to work with ndiswrapper.	No native driver support and ndiswrapper obviously won't work.	There's a previous revision of this dongle which is supposed to have a Ralink chip, but they revised it and put a different chip inside.
Cisco/Linksys AE1000 High Performance Wireless-N USB Adapter	rt3572sta (RT3572USB)	Standard-A	USB 2.0		USB A	Reportedly works.	Works with a modified driver.	Download the driver from ralink's driver site, edit ./common/rtusb_dev_id.c, before "#endif // RT2870" add "{USB_DEVICE(0x13B1,0x002F)},", compile. NOTE: Broke after three days!

LaCie Rikiki 250GB USB 2.0 2.5" Hard Drive	Not required	standard-A	USB 2.0	Unknown	standard-A port via powered High Speed Hub	Not working on Pandora	This drive does not work on a Pandora. Not only does it fail to spin up, but it causes the Pandora's screen to pulsate wildly, much like an old CRT would if you placed a speaker or a magnet near to it. I have not yet tested this with a powered hub.
Verbatim 250GB Model #47580 Hard Drive	Not required	direct	USB 2.0	Unknown	direct	Works on Pandora	Tested by almatuk. "worked an absolute treat when plugged into the Pandora. Watched videos directly from it at full speed, no need for powered USB hub. Had issues playing roms directly off it however as it was formatted NTFS. I'm sure if I formatted to FAT32 these would disappear."

Freecom 250GB 2.5" portable	Not Required	standard-A	USB 2.0	Unknown	Direct	Works on Pandora	Just works perfectly when plugged into the Pandora. Inside it's a Samsung Model HM251JX so I guess anything based on that will also work OK.
