This USB ID is already in the List under the Label "Ralink"

Gah!  I guess I jumped to the wrong conclusion when it didn't work,
because rt2500usb.ko also claims this ID.  Blacklisting rt2500usb and
"adding" the ID in rt73usb got me able to do monitor mode, but I guess
blacklisting rt2500usb was what did the trick.

Sorry for the noise, but maybe the same ID in rt2500usb should be
removed, unless there is some story here about ID reuse...

Unfortunately there have been reports about devices with that USB ID
that contains a rt2500usb chipset. There are a number of duplicate USB ID's
between rt2500usb and rt73usb.
Some manufacturers like to release new revisions of their wireless USB stick
with different chipsets but with the same USB ID.

Oh well.

Are there known problems with the monitor mode?  It seems incomplete
even with one virtual interface, eg

At which rate should the other box be sending the frames?

Could you enable debugfs and do inside the "rt73usb" folder within the
mac80211 debugfs entry do:

echo 16 > csr_offset
cat csr_value

This will read the TXRX_CSR0 register of rt73usb which controls the filtering
of the frames. That will help determining if the missing frames have been
droppen in the hardware or not.

Don't feel bad, monitor mode is not in a coherent state all over the
drivers at the moment.  I would really like to see it become trustable
in all cases.

54Mbps, I am a couple of metres from the AP.

I have to add debugfs in my .config for that, it is rebuilding.

However, I added the following debug line inside the loop at
rt2x00_dev.c function
void rt2x00lib_rxdone(struct data_entry *entry, char *data,
	const int size, const int signal, const int rssi, const int ofdm)

		printk("signal=%d, ofdm=%d, rate->val=%d, val=%d\n", signal, ofdm,
rate->val, val);

and ran tcpdump at the same time.  What I see is that even though
tcpdump on ch 6 is only willing to show 1Mbps packets, packets with
other rates passed through here, eg,

signal=20, ofdm=0, rate->val=4106, val=10
signal=20, ofdm=0, rate->val=16789524, val=20
signal=110, ofdm=0, rate->val=4106, val=10
signal=110, ofdm=0, rate->val=16789524, val=20
signal=110, ofdm=0, rate->val=33583159, val=55
signal=110, ofdm=0, rate->val=50393198, val=110

but ALWAYS ofdm is 0, ie, it only sees CCK packets.

If I look over on channel 11, my neighbour has an 80211b device
apparently, I see data packets at 11Mbps, again CCK.

Ok. That means we can at least assume several frames should
be send with higher rates then 1 Mbs. ;)

I think I have an idea why mac80211 always reports 1 MBs,
rt2x00 checks if PREAMBLE was enabled or not. If that is the case it sets
the rate value to rate->val2
Mac80211 in turn only compares the value against rate->val which
means that it won't find the rate and assume the lowest possible rate.
I'll fix this by always setting the rate->val value instead (It isn't really
important for mac80211 to know if the preamble bit was set anyway).

And here is a big problem..
This register is defined as:

#define TXRX_CSR0_DROP_CRC				FIELD32(0x00020000)
#define TXRX_CSR0_DROP_PHYSICAL			FIELD32(0x00040000)
#define TXRX_CSR0_DROP_CONTROL			FIELD32(0x00080000)
#define TXRX_CSR0_DROP_NOT_TO_ME		FIELD32(0x00100000)
#define TXRX_CSR0_DROP_TO_DS				FIELD32(0x00200000)
#define TXRX_CSR0_DROP_VERSION_ERROR	FIELD32(0x00400000)
#define TXRX_CSR0_DROP_MULTICAST			FIELD32(0x00800000)
#define TXRX_CSR0_DROP_BORADCAST		FIELD32(0x01000000)
#define TXRX_CSR0_DROP_ACK_CTS			FIELD32(0x02000000)

Which means it will only pass multicast, broadcast and ACK_CTS frames. :S
Always dropping CRC errors is correct, since enabling that will greatly upset
any monitoring tool listening to the interface.

To see if it helps try:

echo 16 > csr_offset
echo 0x0002b162 > csr_value

This will disable all DROP bits (except for the CRC error) and thus should
trigger more frames to be received by your interface. In the mean time I'll search
why those bits weren't cleared when enabling the interface in monitor mode.

Which version are you using?

Somehow the rates seem to be correct now after your change to the DROP
bits...

Well one day it will be nice if there is a stack-level way to turn it on
and off.  We can also pass in the radiotap part a flag to show if the
packet's CRC was valid or not.  The tools can then either turn on the
filtering before the packets come or filter on good packets only.

Well the problem with the CRC errors is that, when enabled, mac80211
will be flooded with frames. Regular frames which are usually the interesting
ones could get lost in there.
But you are right, having the stack to control the DROP filter would be a very
nice feature. :)

Ok, rt2x00.git contains many changes to the initialization of the device,
so it is a bit hard to compare at the moment. At least it is confirmed that rt2x00 can
receive all frames in monitor mode and the problem area is the DROP filter.

I'll release rt2x00 2.0.5 later today with all those changes, including the rxdone rate
selection fix. So if you could retest later to see if the problem disappeared in 2.0.5 it
would be great. :)

Ok, that was easier then I thought, rt2x00 2.0.5 _will_ contain the fix for this.
I just noticed that when the first and only interface is a monitor interface
the device was not being configured at all. This has now been fixed in rt2x00.git,
so it will be part of the 2.0.5 release later today. :)

Great, I will check for it on the serialmonkey site later and give it a go.

I just received four different kinds of cheap cards from ebuyer, I hoped
to get a bcm43xx card again but you can't choose when the cards are only
GBP8 each.  So later I will see what can happen with the other cards
that are new to me: Libertas on 88W8335 PC Card, Libertas USB stick
1286:1fab, and a Realtek PC Card RTL-8185.

Thanks to your help it looks like the first RT2571-based one is a winner ;-)

Ah I saw it went to git.kernel.org

Yes current rt2x00 git in there works fine for simple monitor mode
now... thanks a lot for your hard work!
