Dear Felipe, I just want to tell, that while still developing kernels in the 2.6.2X series a kernel 2.6.22 can not be labeled as old. Besides it comes along with few distros as default kernel. A lot of people like me need some kind of a stable version that we can relay on for more than playing at home, which is the case with 2.4.X tree. Personally, experiments with 2.6.24 brought me into a big trouble and it took many hours to migrate back to 2.6.20, so please keep in mind that if we say something like this, there is a good reason to do so. Appreciate your understanding. --- On Wed, 7/30/08, Felipe Balbi <felipebalbi@xxxxxxxxxxxxxxxxxxxxx> wrote: > From: Felipe Balbi <felipebalbi@xxxxxxxxxxxxxxxxxxxxx> > Subject: Re: USB driver issue > To: "SUBHRANIL CHOUDHURY" <subhra85@xxxxxxxxx> > Cc: linux-omap-open-source@xxxxxxxxxxxxxx, linux-omap@xxxxxxxxxxxxxxx, linux-usb@xxxxxxxxxxxxxxx > Date: Wednesday, July 30, 2008, 2:05 PM > Hi, > > On Wed, Jul 30, 2008 at 2:59 PM, SUBHRANIL CHOUDHURY > <subhra85@xxxxxxxxx> wrote: > > Hi all, > > I am trying to validate the USB driver on OMAP3430 > with the > > 2.6.22.18kernel.
