I've been using a streamzap remote control (lirc 0.7.2) and a usb mouse
successfully for about 6 weeks with 3 dvico fusion lite (Bt878a chipset
based) DVB-T cards without usb problems.
Now I've just switched to 3 Kworld (CX8233xx) based DVB-T cards and I've
started to get the irq message which appears to be generated from
usbcore. Can anyone help me debug this problem please.
dmesg , uname, lsmod, & lspci outputs provided below.
Regards Ben
