Hi , I noticed that HVR 930C support was added 21-11-2011. I have build the new driver and installed the firmware but I'm struggling to get it working.

This means that it detected a QAM_256 carrier, at 602000 kHz, with 6.900 Kbauds symbol rate.

-ENOSPC error is generally associated with the lack of USB bandwidth support. This means that the USB bus doesn't have enough free slots for the traffic required in order to support your stream. It generally means that your device is connected into a USB 1.1 hub or port. There are some new USB interfaces that are known to have troubles with the Linux USB 2.0 implementation, as they internally use some USB hubs. It could be your case, as the driver detects it on an USB 2.0 port:

The available bandwidth at the USB bus is given by: T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=480 MxCh= 6 B: Alloc= 0/800 us ( 0%), #Int= 0, #Iso= 0 (in the above example, device is not used) Tuning into a channel spends 19% of the USB bandwidth (e. g. 152 ISOC slots), as shown at: T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=480 MxCh= 6 B: Alloc=152/800 us (19%), #Int= 0, #Iso= 5 The same bandwidth is required by w_scan/scan. You can also try to put your device on another bus and see if this would fix the issue.
