According to http://buffalo.nas-central.org/wiki/Information/LSPROOverview the Linkstation Pro supports the following usb transfer rate:
"Max: 480 Mbps (HS Mode), Max: 12 Mbps (FS Mode) "
It should also work since some German users of the Linkstation Pro published success stories with USB-cards for DVB-T and DVB-S (http://tinyurl.com/oz4l5f). However, I couldn't find any success story for the MediaTV Pro stick yet.
If DVB-S works with it DVB-C will definitely work. There are many different ARM boards out there which have different USB 2.0 specifications.
Since you don't offer the source code: When and how would I get the needed driver after buying the MediaTV Pro?
We have ARM builds, the biggest difference with our driver is that it is based in userspace.
There are 2 drivers available:
1. Full userspace driver (the one which is downloadable)
2. Hybrid userspace driver (which uses an opensource kernel part for the datatransfer)
In any case the userspace driver contains the device configuration and is portable across different kernel versions, this is the requirement we got from several participating chip companies in order to fully support the entire device. In order to get ARM support for your particular system our support can help you by using a remote connection.
It is good to hear that compatible usb-hubs exist. Could you recommend me a compatible hub? Or is there a list with working hubs avaiailable?
This topic is a little bit difficult as we do not have your particular ARM device, you might go to a store and test it directly with a USB storage device, it should have the same effect.
