hi again, i have recently switched to a ppc workstation, no more x86 for me ;-) and guess what, my dvb-t usb box now works!!! :) this box has USB 2.0 (not USB 1.1 like my old x86 PC), I used yesterdays v4l-dvb cvs sources (i did all this yesterday) and a 2.6.14-gentoo-r7 kernel... no more USB disconnects because of too much power drawn from the usb port... :) now i'm finally happy, new cool ppc machine and cool v4l-dvb support! :) thx for your linuxtv/v4l development, steffen > >hi, > >while reading this [1] message i recognized that i also have the same usb >power problems... >
