I'm still struggling with this stick. I have now compiled the modules for a second P4 based system (my primary requirement is on a Arm based system) and see identical results. I have also placed this device behing a powered USB hub and I still get "recv bulk" errors (-71, -110, -75...) each time I try and use it. A second attempt at tuning _always_ results in a system freeze.So, one card, two PC's, with or without a hub and I get reproduceable (bad) results.
 
Is this likely to be a driver or hardware error?
 
Cheers

I wrote over the weekend describing the problems I've been having with my Freecom stick (id 14aa:022b). I've made some progress but am still struggling with the device.
 
Here's the dmesg output
  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'

  dvb-usb: found a 'WideView WT-220U PenType Receiver (based on ZL353)' in warm state.
  dvb-usb: will use the device's hardware PID filter (table count: 15).
  DVB: registering new adapter (WideView WT-220U PenType Receiver (based on ZL353)).
  DVB: registering frontend 0 (WideView USB DVB-T)...
  input: IR-receiver inside an USB DVB receiver as /class/input/input1
  dvb-usb: schedule remote query interval to 300 msecs.
  dvb-usb: WideView WT-220U PenType Receiver (based on ZL353) successfully initialized and connected.
  dvb-usb: recv bulk message failed: -110

Basically when I attempt to tune it using a channels.conf from another system in my house I get a Tuning failure and (sometimes a kernel OOPS) with recv bulk message errors. However, if I follow the recommendations here (HYPERLINK "http://www.linuxtv.org/pipermail/linux-dvb/2006-April/009684.html"http://www.linuxtv.org/pipermail/linux-dvb/2006-April/009684.html ) and change ythe freq for BBC ONE from 641833330 to 642000000 I get a successful lock. dvbdate from the dvb-apps returns the correct date/time but scan results in a system freeze. Once tuned, all further attemps to retune the device (even to BBC ONE) result in a system freeze. Below is an extract from my (modified) channels.conf
 
BBC ONE:642000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_3_4:FEC_3_4:QAM_16:TRANSMISSION_MODE_2K:GUARD_INTERVAL_1_32:HIERARCHY_NONE:600:601:4173

I'm on a Linksys NSLU2 (slug) running Slugos 3.10. All software is cross compiled on a Gentoo PC.  

 

 
All assistance is greatly appreciated.
 
Cheers
 
Mark
