I have recently bought a stir4210 usb 2.0 dongle and can't get it configu= red. There is a GPLed driver available but it seems it's only for the 2.4 kern= el. And I'm sad to say I'm no coder... I was trying to get it to work with the stir4200 driver from the 2.6.12-rc6 kernel but had no luck. It does detect it, and irdadump is finding the computer from which it's running b= ut it doesn't detect any irda devices I'm throwing at it(atm only a nokia 61= 10). This is the device I have: http://www.equip-info.net/english/index.php?main=3D0&suche=3Dirda&prod=3D= 1508 Also on that site is a link to the drivers. If you require more info please let me know what I can do to help. --=20 Andrew "ruskie" Levstik Source Mage GNU/Linux Games grimoire guru Key id =3D 9A5117F8 Key fingerprint =3D 6731 FEF2 99A8 4672 5962 69AB 3DAF DA67 9A51 17F8 |

You need hotplug and a current version of irdautils. If you are still using devfsd, your driver module will get loaded. If udev, be sure hotplug loads it.

it appears that the difference between the 4200 and the 4210 is that the 4210 is a USB 2.0 device capable of 16m transfer speeds. to support the 4200 i included usb support for uhci, ehci and ohci. not all three are necessary in my case but you certainly will need 2.0 support. udev device discovery does create an entry in /dev for devices that are present at boot(which ones and how depend on its configuration files). it is a little slow on the uptake for devices which are hotplugged. i don't run the daemon so it usually takes udev restart to make it reread /sys and find the new entries. additionally these irda options are set: CONFIG_IRDA=m CONFIG_IRNET=m CONFIG_IRCOMM=m CONFIG_IRDA_CACHE_LAST_LSAP=y CONFIG_IRDA_FAST_RR=y CONFIG_IRDA_DEBUG=y CONFIG_IRTTY_SIR=m CONFIG_SIGMATEL_FIR=m my guess is that the 2.6 4200 driver should work for you unless the 4210 returns a specific signature as a consequence of a device probe the driver simply can not recognize. in any event the core usb drivers (in your case usb 2.0) should see the device if it's plugged in and you should be able to see that in /sys if you have it mounted to the kernel's /proc device directory. ----- Original Message ----- From: "Andrew "ruskie" Levstik" <ru...@ma...> To: <ird...@li...> Sent: Saturday, September 17, 2005 3:08 PM Subject: Re: [irda-users] stir4210 device > You need hotplug and a current version of irdautils. > If you are still using devfsd, your driver module will get loaded. > If udev, be sure hotplug loads it. > Put the attached scripts in the appropriate hotplug locations. > Reboot. > Thank you...

Andrew: I missed this post earlier. The 4200 driver sees the device and appears to be having considerable negotiation problems with it. if changing the irda parameters doesn't clear it up(unlikely), then upgrading the 4200 driver or bringing the 2.4 4210 driver forward may be your only alternative. the net drivers create a 'netdev' symbolic like 'eth0' which 'irattach' and ifconfig manipulate. unlikely you'll ever see anything in /dev for these. i don't think the changes to the 4200 driver would be too extensive. famous last words. ----- Original Message ----- From: "Andrew "ruskie" Levstik" <ru...@ma...> To: <ird...@li...> Sent: Friday, September 16, 2005 11:31 AM Subject: Re: [irda-users] stir4210 device Andrew "ruskie" Levstik wrote : > I have recently bought a stir4210 usb 2.0 dongle and can't get it > configured. > There is a GPLed driver available but it seems it's only for the 2.4 > kernel. > And I'm sad to say I'm no coder...

AFAIK the STIR 4200 and STIR 421X devices are completely different: the 4200 has some proprietary (but documented) usb interface (eg. register settings, etc) while the 421X series conform to the irda-usb class specification. BUT they need some firmware patches loaded before they can be used. I think the driver provided by sigmatel is a patched version of Linux' usb-irda driver that will support the preloading of the firmware patches. maybe these changes have made there way into the most recent stock linux usb-irda drivers, (i have no idea if they did recently, but they are missing at least in 2.6.12) but anyway, you need these firmware patches. They are _NOT_ GPL, and can be downloaded from http://www.sigmatel.com/documents/stir4210_4220_4116_patch_files.tar.gz as they are not GPL'ed, i suppose that your distribution does not include them, so you need to download these firmware files, install them soewhere, and set up hotplug to load these patches. if sigmatel's patches have not found their way into the stock kernel driver and you try to write support on your own, you need to modify the usb-irda driver, not the stir4200 driver. good luck, tom William Adams schrieb: > Andrew: > > I missed this post earlier. > The 4200 driver sees the device and appears to be having considerable > negotiation problems with it. if changing the irda parameters doesn't > clear it up(unlikely), then upgrading the 4200 driver or bringing > the 2.4 4210 driver forward may be your only alternative. > > the net drivers create a 'netdev' symbolic like 'eth0' which 'irattach' > and ifconfig manipulate. unlikely you'll ever see anything in /dev > for these. > > i don't think the changes to the 4200 driver would be too extensive. > > famous last words. > ----- Original Message ----- From: "Andrew "ruskie" Levstik" > <ru...@ma...> > To: <ird...@li...> > Sent: Friday, September 16, 2005 11:31 AM > Subject: Re: [irda-users] stir4210 device > > > Andrew "ruskie" Levstik wrote : > >> I have recently bought a stir4210 usb 2.0 dongle and can't get it >> configured. >> There is a GPLed driver available but it seems it's only for the 2.4 >> kernel. >> And I'm sad to say I'm no coder...

an examination of the sigmatel 4210 driver suggests this is correct. however it seems the loading of the firmware is about all it does do. stripping the surrounding wrapper from the sigmatel patch files, uppercasing them and using fxload via hotplug to load them is what comes to mind along with a few parameter changes to the 4200 driver. it's not guaranteed to work and the non gpl nature of the patch files is certainly a problem. the idea of a gpl driver that does little besides loading non gpl code is disturbing. ----- Original Message ----- From: "Thomas Ilnseher" <il...@gm...> To: <ird...@li...> Sent: Sunday, September 18, 2005 3:21 PM Subject: Re: [irda-users] stir4210 device > AFAIK the STIR 4200 and STIR 421X devices are completely different: > > the 4200 has some proprietary (but documented) usb interface (eg. register > settings, etc) > while the 421X series conform to the irda-usb class specification.

I am serious, vendors building proprietary drivers out of GPL code is wrong. |

So the driver needs to upload a patch for this _firmware_ running on the device (aka on your irda dongle) so that the device works properly. after this has happened, the device works like any other irda-usb compilant device. so the Firmware patches do not violate GPL. look at this as something like an hardware upgrade. All that is executed by your host cpu (aka the intel / AMD/ via thingie) is GPL, as their modified driver _IS_ GPL. all what needs to be done is to update irda-usb driver in 2.6 to upload this firmware patches. get your hands off the STIR4200 driver, as the STIR4200's are totally different from the STIR421X devices ! using fxload is AFAIK not possible, cause fxload was designed to upload firmware into the Cypress AN2312 chips, which i think use a different method of uploading the firmware then this devices do. to say it short: SigmaTel is NOT wrong. what they did is legal and good.

> Maybe i said it the wrong way, so you all get me wrong ;) Your right, I am wrong. No body but the Debian "all firmware must be open source" fanatics will care. The more general fix for this seems to be either fixing fxload and/or getting the hotplug firmware loader to work for USB devices. |

a look into the history of the stir4200 suggests it is not and never will be irda spec compliant. kludges were installed in the irda code to make it run. the 4210 seems to have rectified this problem and with the exception of needing the patch will run without the aid of anything else. hotplug seems a viable option but testing will be necessary and i don't have a 4210. after the 1st, i'll try and bring the "driver" forward for you unless you have succeeded elsewhere. wouldn't you love to know what happens on Windows? ----- Original Message ----- From: "Andrew "ruskie" Levstik" <ru...@ma...> To: <ird...@li...> Sent: Tuesday, September 20, 2005 3:44 AM Subject: Re: [irda-users] stir4210 device William Adams wrote : > an examination of the sigmatel 4210 driver suggests this is correct. > however it seems the loading of the firmware is about all it does do. > stripping the surrounding wrapper from the sigmatel patch files, > uppercasing them and using fxload via hotplug to load them is > what comes to mind along with a few parameter changes to the > 4200 driver. > > it's not guaranteed to work and the non gpl nature of the patch > files is certainly a problem. > > the idea of a gpl driver that does little besides loading non gpl > code is disturbing. > > ----- Original Message ----- > [---=| TOFU protection by t-prot: 143 lines snipped |=---] > > So is there any way I can get this working.
