Date: Sat, 8 Oct 2011 16:00:06 -0700 (PDT) From: AW <arne_woerner@...oo.com> To: "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org> Subject: Re: acm/ttyACM0/cdc_acm does not deliver data I tried a vanilla kernel now (built from the fedora SRPM after some help by Piotr H....)... The command that works on the vanilla kernel (_and_ on the official fc15 kernel) looks to usbmon on the vanilla kernel like this: http://www.wgboome.org/cmd:P-C,2.6.40.6-0.local.fc15.x86_64.usbmon (the command "P C" switches receive/send-roles much faster (i guess: less than 1msec) than the command "Z L 0" (I guess 50msec); during that time interrupts r disabled and the ATtiny doesnt care for USB things... *blush* but why did the "old" USB subsystem didnt complain about it? and what about my professional DVB-T USB sticks?) On the vanilla kernel the command "Z L 0" doesnt work as before: http://www.wgboome.org/cmd:Z-L-0,2nd-try,2.6.40.6-0.local.fc15.x86_64.usbmon -arne -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
