WUSB54GC wireless USB stick (usb1737,77)

In order to get wireless working I tried several things, so far not successful.
According to other bloggers I have a new version based on Ralink RT3090
Information I gathered so far:

To find out which usb devices are connected run as root:
# echo ::prtusb | mdb -k
INDEX DRIVER INST NODE VID.PID PRODUCT
1 ehci 0 pci1043,82e2 0000.0000 No Product String
2 ehci 1 pci1043,82e2 0000.0000 No Product String
3 ohci 0 pci1043,82e2 0000.0000 No Product String
4 ohci 1 pci1043,82e2 0000.0000 No Product String

6 hid 2 mouse 046d.c03d USB-PS/2 Optical Mouse
7 usb_mid 1 device 1737.0077 802.11 g WLAN

Hmm, this device is new version, which is a Ralink 3090 chipset,

#modinfo
#devfsadm -i
#dmesg | grep Ralink

SUNWural
Package SUNWural didn't work so I removed package
SUNWrum
Also tried with SUNWrum package (rum driver) but no.
# update_drv -a -i "usb1737,77" rum
# ifconfig rum0 plumb

From Ubuntu Forum: Problem solved! idea
I have to rename /etc/Wireless/RT3090STA to /etc/Wireless/RT2860STA
Although it is a RT3090 driver, it uses RT2860 as its internal reference. confused2
Anyway, I can connect to the Internet with no problem now.

#iwconfig to configure it

nwam will configure interface automatically (NetWork Auto Magic = Standard on opensolaris)
Note that in auto-magic mode, there is a limitation that only one link is active at a time. This mode is thus not recommended for machines which use more than one link at once. For machines with wired and wireless links, wired is preferred by default, although this can be adjusted by altering the order of the lines in the plain text file /etc/nwam/llp. Note, however, that this interface is Volatile and may change in a future release.
