Hey Jason, We have access to the following firmwares for it913x:
http://palosaari.fi/linux/v4l-dvb/firmware/IT9135/12.10.04.1/IT9135v2_3.40.1.0_3.17.1.0/ http://palosaari.fi/linux/v4l-dvb/firmware/IT9135/12.10.04.1/IT9135v2_3.42.3.3_3.29.3.3/ and of course the one the kernel uses: http://www.ite.com.tw/uploads/firmware/v3.6.0.0/dvb-usb-it9135.zip Will any work with the dual it9137/9133?
