Hello there,

I would like to report that Nebula Electronics uDigiTV DVB-T USB2.0
drivers in the current stable 2.6.15.2 kernel do not work.

Syslog reports:

Linux video capture interface: v1.00
bttv: driver version 0.9.16 loaded
bttv: using 8 buffers with 2080k (520 pages) each for capture
bt878: AUDIO driver version 0.0.0 loaded

dvb-usb: Nebula Electronics uDigiTV DVB-T USB2.0) successfully

I have also tried all 5 v4l-dvb snapshots available at
http://linuxtv.org/downloads/snapshots/ with no luck. They reported the
following in the syslog:

Linux video capture interface: v1.00
bttv: driver version 0.9.16 loaded
bttv: snapshot date 2006-01-15
bttv: using 8 buffers with 2080k (520 pages) each for capture
bt878: AUDIO driver version 0.0.0 loaded
usbcore: registered new driver dvb_usb_digitv
usb 4-1: new high speed USB device using ehci_hcd and address 3
dvb-usb: found a 'Nebula Electronics uDigiTV DVB-T USB2.0)' in cold
state, will try to load a firmware
dvb-usb: downloading firmware from file 'dvb-usb-digitv-01.fw'
dvb-usb: firmware download failed at 4956 with -22
dvb_usb_digitv: probe of 4-1:1.0 failed with error -22

I could not try the latest development version from mercurial, since
digitv.c implies that I need a new firmware file dvb-usb-digitv-02.fw,
which I haven't managed to find from anywhere.

lsusb reports the Nebula USB box as:
Bus 004 Device 004: ID 0547:0201 Anchor Chips, Inc.

The sticker at the bottom of the device doesn't say much. Mostly 
"©Nebula Electronics Ltd 2005" and "Master Tuner uDigiTV USB 2.0". :)

Please let me know if I can help in solving the issue by providing any 
additional information.
