The Proxim USB stick is an AR9170 based adapter. ORiNOCO is just a brand name that they have plastered over all their wireless products. It has no real bearing anymore unless you happen to be referring to the Classic cards based on the HERMES I chipset. Like (most if not) all other AR9170 devices it will work in Linux with ar9170 or the new carl9170 modules.

I haven't had good experiences with the ar9170 driver in general (bad packets in monitor mode, issues with multiple cards, general instability), but that may just be my particular setup.

anyway, the adapters I would recommend if ye want dual band snifferization (in order of perceived usefulness)...

ALFA AWUS051NH (or the AWUS050NH)
-abgn, Ralink RT2770+RT2750 chipset (1T2R)
-corded
-works fine w/ a recent stable version of compat-wireless
-has an RP-SMA connector

Airlink AWLL7025
-abgn, Ralink RT2870+RT2850 chipset (2T2R)
-dongle
-works fine w/ a recent stable version of compat-wireless
-cheap

additional Ralink-based USB adapters include..
-WUSB600N v1 [RT2870+RT2850] and v2 (also known as the AE1000) [RT3572]
-Buffalo WLI-UC-AG300N and WLP-UC-AG300 [both RT2870+RT2850]
-SparkLAN WUBR-505N [RT2870+RT2850]
-TRENDnet TEW-664UB rev A [RT2870+RT2850]
-D-Link DWA-160 rev B1 [RT2870+RT2850]
-Motorola TER-NUSB1 [RT2770+RT2750]
-JJPlus EM9 [RT2770+RT2750] (non-dongle)
-EnGenius EUB9801 [RT3572]
-Samsung WIS09ABGN [RT2870+RT2850]
-Samsung WIS09ABGN2 and WIS10ABGN [RT3572]
-Askey WLU5022 [RT3572]
-SIIG CN-WR0212-S1 [RT2870+RT2850?] (unconfirmed)

Dell Wireless 1450 USB Adapter (additionally the Linksys WUSB54AG)
-abg, Intersil PRISM (ISL3887+ISL3692) chipset
-corded
-well supported with p54usb (CX9207UZ models atm require patching of the drivers for signal strength info)

Netgear WNDA3100 v1 (and v1 only, v2 [with the WPS button] is Broadcom based)
-abgn, Atheros AR9170+AR9104 chipset (2T2R)
-dongle
-cheap, refurbs are everywhere

Ubiquiti SR71-USB
-abgn, Atheros AR9170+AR9104 chipset (2T2R)
-dongle
-dual MMCX connectors
-quite expensive

I would maybe put some ZyDAS based adapters on there, but I haven't actually tried any. Also, more info on cards may be available at http://www.wikidevi.com/wiki/Special:BrowseData if you can wade through the terrible.

note: I would be unsure if any of the N devices are going to actually report N (HT20/HT40) packets, especially by default.
