Hi,
 
I have a Freecom USB DVB-T stick. I have d/loaded the drivers from the mercurial archive and compiled/installed the following drivers :- dvb-core, dvb-usb, dvb-usb-dtt200u.  All seems to be well, I grabbed the firmware file 'dvb-usb-wt220u-zl0353-01.fw' and the card lights up its LED. However, dmesg reports a 'bulk message' error

	dvb-usb: found a 'WideView WT-220U PenType Receiver (based on ZL353)' in cold state, will try to load a firmware
	dvb-usb: downloading firmware from file 'dvb-usb-wt220u-zl0353-01.fw'
	usbcore: registered new driver dvb_usb_dtt200u
	usb 1-2: USB disconnect, address 3
	dvb-usb: generic DVB-USB module successfully deinitialized and disconnected.
	usb 1-2: new high speed USB device using ehci_hcd and address 4
	usb 1-2: configuration #1 chosen from 1 choice
	dvb-usb: found a 'WideView WT-220U PenType Receiver (based on ZL353)' in warm state.
	vb-usb: will use the device's hardware PID filter (table count: 15).
	VB: registering new adapter (WideView WT-220U PenType Receiver (based on ZL353)).
	VB: registering frontend 0 (WideView USB DVB-T)...
	nput: IR-receiver inside an USB DVB receiver as /class/input/input1
	vb-usb: schedule remote query interval to 300 msecs.
	vb-usb: WideView WT-220U PenType Receiver (based on ZL353) successfully initialized and connected.
	dvb-usb: recv bulk message failed: -110

 and when I try and tune the card I get the following output

	root at slug1:/dev/dvb/adapter0# tzap -F "BBC ONE"	
	using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
	reading channels from file '/root/.tzap/channels.conf'
	tuning to 641833330 Hz
	status 00 | signal ffff | snr ffff | ber 00000000 | unc 00000000 |
	status 20 | signal ffff | snr ffff | ber 00000000 | unc 00000000 |
	status 20 | signal ffff | snr ffff | ber 00000000 | unc 00000000 |

So, not tuning :( plus every third attempt (or so), results in a kernel OOPS

dvb-usb: bulk message failed: -71 (2/0)
usb 1-2: USB disconnect, address 4
dvb-usb: bulk message failed: -19 (1/0)

I'm on an arm processor with kernel 2.6.16.

Any help would be _really_ appreciated as I'm completely lost as to what to do next.

Thanks

Mark
