Hi, I have a DCDTV350 usb dmb t/h tuner which is mis-detected, it shows as having a sharp S921 tuner instead of the lgs tuner, (it is *not* an ISDB-T device ;) and when i try and tune with it, it generates an oops, (in 3.11), or doesn't work at all in 3.2/3.5) attached is the lsusb & the dmesg output.(and the oops)
it has an empia 2874, Legend silicon LGS-8g54-at tuner, an AD9216, and a ADMTV102 (and an 8x16 SDRAM) if i remember correctly there is support for both the main chips, but they are not together in one driver, I will be going to china in a couple weeks, so if anyone could send me a patch I am more than willing to test it :) Thanks!
