I had similar issue!! with RT2870 based Linksys WiFi Dongle.
I did not workaround much, due to lack of experience and time ;)
Instead switched to RT73 based D-Link DWA110 .
It Worked great without any problem!! [Plug n Play]. Works in both Ad-
Hoc and Managed Mode.
Netgear WG111V3 also works in Managed Mode, but I could not bring it
up in Ad-Hoc Mode.
Btw, which version of Kernal are you using ? I had used 2.6.31.5-x5.3
I could help you with D-Link as I am working on it.
Experts could help you better with 2870 :)

What Kernel? (uname -a)
The RT2xxx devices usually have two drivers in the kernel. In staging
the Ralink gpl driver and the rt2x00 project...

Some users have had better luck with this hardware by using the
network-manager gui vs iwconfig...

I don't remember if 2.6.32.7-x7.1 had those modules external or internal...
But with 2.6.32.9-x9.1 they are here:
ls -lh /lib/modules/`uname -r`/kernel/drivers/net/wireless/rt2x00
total 180K
-rw-r--r-- 1 root root 28K 2010-02-25 10:17 rt2500usb.ko

Look again, it's there... "--kernel image" extracts a *.deb file
directly to /lib/modules/
i did use a RT73 DLink device as well, lsusb gave me:
Bus 001 Device 042: ID 07d1:3c03 D-Link System DWL-G122 802.11g
Adapter ralink rt73
It did work really well out of the box (in ubuntu and angstrom) as
long as I turned off WPA encryption, but I am not sure wether this is
due to the hardware or other settings. Ad-Hoc worked as well.
BUT: whenever the system gets laoded, I end up with a driver crash.
This usually happens to me after ~30 minutes to a few hours. At this
stage I can unplug the device and replug or reboot the machine, but
this is not quite satisfactory. I have since ordered a few more
different WLAN devices to test since they are quite cheap.
If this is not a big concern (I am able to install packages and such)
it does work well.

Looks like it kinda works...
Note, Some users have had better luck keeping the connection going
thru network-manager then thru the iwconfig interface..

Hi Avinash,
thanks for your advice! Could you tell me whether with the RT73 D-link
DWA110 you could do anything that you could with a wired network..
i.e. ping, wget any website or even use firefox in the GUI?
Thanks,
Gianluca

Actually, one step a head of you, it's Kconfig was set correct (wasn't
built on arm) and I just enabled it with in the last couple days..
I've been fighting it too with my wifi adapters...
Use 2.6.32.11-x12
voodoo@beagle-256mb-0:~$ ls -lh
/lib/modules/2.6.32.11-x12/kernel/drivers/staging/rt2870/
total 548K
-rw-r--r-- 1 root root 544K 2010-04-02 18:20 rt2870sta.ko
You'll more then likely have to set "/etc/modprobe.d/blacklist.conf"
just like on the x86, since all the rt28xx usb drivers are built as
modules....
