Hello, I recently tried to build and use the EC168 drivers from <http://linuxtv.org/hg/~anttip/ec168/> following instructions found at <http://www.dealextreme.com/forums/Default.dx/sku.8325~threadid.278942> The drivers built fine but upon trying to load dvb-usb.ko (sudo insmod ./dvb-usb.ko) I got the following error: insmod: error inserting './dvb-usb.ko': -1 Unknown symbol in module dmesg listed these additonal errors: [ 647.189929] dvb_usb: Unknown symbol release_firmware [ 647.190085] dvb_usb: Unknown symbol request_firmware I am running Debian 5.0 with the stock kernel (2.6.26-2-amd64) on an HP ML115 server (Quad-Core AMD Opteron(tm) Processor 1352, 4GB ECC memory) I found I was able to work around the issue like so: 1. First load and then unload the stock dvb-core and dvb-usb included with lenny. sudo modprobe dvb-core sudo modprobe dvb-usb sudo rmmod dvb-core sudo rmmod dvb-usb 2. Then load the modules built from the EC168 tree. sudo insmod ./dvb-core.ko sudo insmod ./dvb-usb.ko sudo insmod ./ec100.ko sudo insmod ./mxl5005s.ko sudo insmod ./dvb-usb-ec168.ko The stick then works and I can use it to view tv etc, unplug/reinsert it and unload/reload the EC168 tree modules without carrying out step 1 again (until the next reboot). The stick is a cheap generic USB stick purchased from eBay (USB id 18b4:1001). Photos of it are here: <http://img89.imageshack.us/gal.php?g=img1283g.jpg> Strangely the markings on the large main chip appear to have been removed by the stick manufacturer (though I think it must be an EC168) The smaller tuner chip has also been scrubbed but the following markings can still be identified: Maxline MXL5003 D37T5:1 Thanks for your time. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
