Re: DVB-S2 PCTV 460e (tda10071) usb issues

This is Sundtek's own shop: http://sundtek.com/shop/Digital-TV-Sticks/ I have the "Media TV Digital Home", which supports DVB-T and -C. You'll need the "SkyTV Ultimate" for DVB-S/S2. There are other sources for these sticks, too. Might be worthwhile to check to save on shipping costs. A word of caut...

Re: DVB-S2 PCTV 460e (tda10071) usb issues

I may be well off track here, but my Sundtek DVB-T/C USB stick can be switched from isochronous to bulk transfer mode with a command line program. Maybe something similar is available for your device? I don't know about PCTV systems, but Sundtek's support for Linux devices is known to be very good. ...

I do use apt-get regularly, but the kernel/boot files in the standard repository haven't been updated for quite a while now.

rpi-update hangs whole system

Hello Forum, I just cannot get "rpi-update" to work reliably on my Pi. More often than not, the command will never complete and hang the whole system.

Jamesh, no need to take such criticism personal.

Do you only get the "failed to read register index..." messages before having to reboot, or are there other errors logged to dmesg, too?

The fact that they run better with the powered hub would point to it being power related. I didn't write that the PL2303 adapters run better with a powered hub.
