[PATCH] IrDA: TOIM3232 dongle support

Hi David,

Here goes a patch for supporting TOIM3232 based serial IrDA dongles.
The code is based on the tekram dongle code.

It's been tested with a TOIM3232 based IRWave 320S dongle. It may work
for TOIM4232 dongles, although it's not been tested.

Cheers,
Samuel.

[PATCH 7/9] IRDA: adjust pnp_register_driver signature

Remove the assumption that pnp_register_driver() returns the number of
devices claimed.

irda-usb

Hello,
I've read some problems with sigmatel 4210 devices 
(like conceptronic CiR4U).
Wwhen the dongles is connected appears an error like:

IRDA-USB found at address 3, Vendor: 66f, Product: 4210 
irda_usb_parse_endpoints(), And our endpoints are : in=02, out=01 (512), 
int=00 Assertion failed!
drivers/net/irda/irda-usb.c:irda_usb_parse_endpoints:1243 
self->bulk_out_mtu == 64 
irda_usb_init_qos(), dongle says speed=0x37F, size=0x20, window=0x8, 
bofs=0x80, turn=0x4 
IrDA: Registered device irda0 

The error "Assertion Failed" is due to a problem with the support 
for EHCI-HDC,
it can be solved deactivating this module (if you configure it like a
module).

Regards
 Vicent Tamarit

The message above can be ignored and commented out in the new experimental 
irda-usb.c module.

It can be ignored, but not commented out. The maximum length for
bulk_out_mtu should be 64, 512 is just out of spec.

sniffing infrared traffic

I want to sniff the traffic between two infrared enabled devices (two
mobile phones) using a linux laptop.                    

Is it possible to (re)configure the irda modules so that it is possible to
only sniff the traffic, and that the laptop does not interact with the phones?
I have the problem that the phones want to comunicate with the laptop instead
with each other.

Disabling Discovery on the laptop does not help. Any pointers in the right
direction are highly appreciated.

Regards,

Paul

	That's actually an interesting project, but there is some work
to do, and some of it might be messy. Most of what you need is already
in place. The only problem is to manage speed changes.

	The first issue is that IrDA is directional with a narrow
angle, which make it impossible to aim in two different directions at
180 degrees. One solution is to use multiple dongles to spy on the
linux box. The other solution is to use a mirror, and have all 3
devices in front of the mirror. Lastly, irdadump parsing support
unbalanced parsing, so even if you spy only one device, irdadump can
do something with that.
	Now, for discovery. In theory, phones should only try to
connect to devices that implement the service they require. They often
use the 'hint' bits to select which device to connect to. So, you you
unload all ircomm modules and kill any Obex application, Linux should
stop advertising those services, and the phone should try to connect
to the other phone.

	You need to identify it at the USB level. Check the Wireless
LAN howto on how to identify a card, basically you need to use 'lsusb'.
	There is 2 types of USB devices that are supported, the old

Angelo, did you manage to retrieve your device's USB IDs (vendor and
product) ?
