[linux-dvb] Nebula USB MT352 slave device not working

Hello,

I have not been able yet to find a solution or indeed any other similar 
problem.  This is my first post to this mailing list.

I have four Nebula Electronics tuners: 1 PCI (NXT6000), 2 USB master (MT352)  
and 1 USB slave (MT352).  They are all the DVB terrestrial versions.

My AMD 32bit based PC is running Fedora Core 6.0.

The antenna is chained through all the devices with the source going in to the 
slave device.  All devices work perfectly except the slave which despite 
being recognised perferctly as far as I know does not work.  I don't have 
Windows on the machine but I have been able to confirm that at least one of 
the master and the slave device work on a Intel based laptop running Nebula's 
software and drivers under Windows XP.

I have attempted to capture from the device but the results are consitent with 
the dvbscan below, the problem is not just with scanning.

It would be great if someone could point me in the right direction please.  
Many thanks.
