Dib0070 i2c write failed / read failed pinnacle 72e
I've recently moved my mythdora backend to a VMware ESXi hosted VM, I'm using USB passthrough to pass my pinnacle pctv 72e DVB USB stick to the VM. At around this time I started to notice the pctv/driver fail, dmesg says "DiB0070 i2c write failed" or read failed. The only way to get it back is to reboot the VM. This is now happening almost daily, dispite a cron scheduled reboot each night.
The only two main changes are that
a) The VM is now 64bit, rather than 32bit
b) The old backend started up and shutdown automatically, so I don't really know if this problem used to exist because of the regular resets of the hardware.
I've seen reference to this problem on various web sites talking about various different tv grabber cards/USB sticks, but no solutions.
Does anyone have any ideas?
