Since change to Linux 4 (July update) lot of people with RTL832u TV tunners said that the module is broke and it stop working. Some people patch that reinstalling the previous Linux 3.x kernel.
2 months later is RTL2832u working again?
I also could not get it work. However, driver successfully loads according to dmesg:
[ 10.002289] rtl2832 3-0010: Realtek RTL2832 successfully attached
[ 10.002335] usb 1-1.5: DVB: registering adapter 0 frontend 0 (Realtek RTL2832 (DVB-T))…
but when initiating a scan from tvheadend (from the remote console at setup), messages are:
[ 1733.507387] r820t 4-001a: r820t_write: i2c wr failed=-32 reg=0c len=1: f9

[ 1737.525353] rtl2832 3-0010: i2c reg read failed -32
(repeated corresponding to the number of frequencies, 3 times in my case) .
It does not work in the August release too.
(ariel connection is adequate, config is raspberry2, booted from SDcard, storage is on USBstick)
have you tried a complete power down of the pi and any hub that your tuners are connected to?
No. It does not work, dmesg produces the same:
even after boot there a successfull driver load section:
[ 9.640520] usb 1-1.5: dvb_usb_v2: ‘Realtek RTL2832U reference design’ successfully initialized and connected
[ 9.643049] usbcore: registered new interface driver dvb_usb_rtl28xxu
[ 9.703125] rc rc0: lirc_dev: driver ir-lirc-codec (dvb_usb_rtl28xxu) registered at minor = 0
.
.
[ 30.750967] usb 1-1.5: DVB: adapter 0 frontend 0 frequency 0 out of range (174000000…862000000)
then - after other, not RTL2832 related, messages- there are severel times repeated message:
[ 30.837953] rtl2832 3-0010: i2c reg read failed -32
[ 31.701370] rtl2832 3-0010: i2c reg read failed -32

[ 32.197265] rtl2832 3-0010: i2c reg read failed -32
Having done a force scan from tvheadend, there are the same messages.
So bad. I think (but I have no data, only the feelings about what I read in Internet) that is the most used DVB-T tunner.
