upgt* at uhub? port ?
upgtdriver supports the USB 2.0 Conexant/Intersil PrismGT series wireless adapters based on the GW3887 chipset.
These are the modes the
upgt driver can
upgt driver can be configured to use
Wired Equivalent Privacy (WEP) or Wi-Fi Protected Access (WPA-PSK and
WPA2-PSK). WPA is the current encryption standard for wireless networks. It
is strongly recommended that WEP not be used as the sole mechanism to secure
wireless communication, due to serious weaknesses in it. The
upgt driver relies on the software 802.11 stack for
both encryption and decryption of data frames.
A prepackaged version of the firmware can be installed using fw_update(1).
# ifconfig upgt0 scan
The following hostname.if(5) example configures upgt0 to join network “mynwid”, using WPA key “mywpakey”, obtaining an IP address using DHCP:
nwid mynwid wpakey mywpakey dhcp
upgtdriver first appeared in OpenBSD 4.3.
upgtdriver was written by Marcus Glocker <email@example.com>.
The hardware specification was reverse engineered by the people at http://www.prism54.org.
upgtdriver just supports the USB 2.0 devices (GW3887 chipset) but not the USB 1.0 devices containing the NET2280, ISL3880, and ISL3886 chipsets. Some further efforts would be necessary to add USB 1.0 support to the driver.
