Hi all, I am using kernel 2.6.13 vanilla (latest stable from kernel.org) with 1x Hauppauge Nova CI DVB-S, 1x Avermedia 761 DVB-T and 2x TwinHan Aplha USB DVB-T sticks. The device drivers load fine, all frontends register. As soon as an application (eg. tzap and/or VDR) is started, the machine stops responding. Only a powercycle fixes it. I have logging enabled for the dvb-usb driver but can find no syslog entries for this. This problem also occured with 2.6.12.5 patched with the dvb patch. Note that using only one Twinhan together with the other 2 DVB cards works fine. Note the TwinHan sticks were tried both on one USB and on seperate USB hubs with the same result. I remember someone talking about excessiver power requirements (eg. more than the USB spec) for these USB sticks. Any suggestions ? Regards
