After some time device hangs and lots of messages in syslog appear very fast: failed_reg_urb ... You could only restart the machine. Therefore the zd1211 driver is unusable for serious work. But I found solution for that. I have removed the ehci_hcid USB 2.0 module and the problem disappeared. So it must be some interaction between this module and zd1211. Someone should solve this bug because obviously running without USB 2.0 is not a perfect solution. I am using debian unstable, kernel 2.6.16. z. --- Using Tomcat but need to do more?

Unplugging and replugging the device is enough to get things working again. Not here, sorry, I wish that it was true...

Let me know how you get on (either outcome) I'm trying this: I'm listening to a web radio, downloading a movie from archive.org and emerge --fetchonly kde for ((i=0;i<1;i+=1)); do cat /proc/bus/usb/devices ; done No way, it doesn't give any sign of a disconnect...
