Subject: [PATCH] rt2800usb: Move ID out of unknown

Testing on the openSUSE wireless forum has shown that a Linksys
WUSB54GC v3 with USB ID 1737:0077 works with rt2800usb when the ID is
written to /sys/.../new_id. This ID can therefore be moved out of UNKNOWN.

The OP is using an openSUSE distro kernel so we don't have the chance to get
info from that source. With lsusb, we get Bus 001 Device 002: ID 1737:0077
Linksys WUSB54GC v3 802.11g Adapter [Ralink RT2070L]. Does that help?

I just ordered one of these devices from E-bay. I can get you more info when it
arrives.

We've got these devices is the UNKNOWN section because we don't know
what chipset is used by these devices (and therefore the level of
support is unknown).

Do you know which chipset is used by this device?

This should be reported in dmesg when CONFIG_RT2X00_DEBUG is enabled.

Yes, that helps. This most probably is an RT3070-based device that uses
an RF2020 RF chipset. We have seen these kind of devices before and they
indeed are properly supported.

Your patch make sense, however, could you please list this USB ID with
the other Linksys USB devices further up in the list. We have ordered
the list on manufacturer name, alphabetically ordered.
