Infact it is one of the general purpose io (gpio-23) to which usb interrupt line is connected and gpio is programmed as an interrupt. I am getting the 'sof' interrupt continuously (at every 1msec) and I can see the corresponding interrupt count in /proc/interrupts is incrementing accordingly. Regarding hc 1161a, I have been told by phillips factory people that the driver is working fine with the x86 platform. I did a port to the powerpc platform. >From: Greg KH >To: ckbb ckbb >CC: linux-kernel@vger.kernel.org >Subject: Re: USB device not accepting new address=2 (error=-19) >Date: Tue, 19 Aug 2003 16:50:12 -0700 > >On Tue, Aug 19, 2003 at 07:33:32PM -0400, ckbb ckbb wrote: > > I am stuck with the following error.
