Switching to a 2.6 host isn't the only reason to try 2.6; another one is just that it's got a more correct and functional USB stack. > Is there any alternative way to avoid this problem using 2.4 kernel? I don't know, but that's much of why I asked whether 2.6 has the same issue. If it does, then both kernels need some bugfix. If not, then you can see what it's doing differently and backport something relevant. - Dave > > > Regards, > Shalini G > > -----Original Message----- > From: David Brownell [mailto:[EMAIL PROTECTED] > Sent: Tuesday, April 26, 2005 2:51 AM > To: linux-usb-devel@lists.sourceforge.net > Cc: Shalini Rao (WT01 - TELECOM SOLUTIONS); [EMAIL PROTECTED] > Subject: Re: [linux-usb-devel] Usb serial with Power ON and OFF problem > > On Monday 25 April 2005 6:07 am, [EMAIL PROTECTED] wrote: > > > The scenario is like, mobile is in charging and if it is OFF, the > device > > (mobile) is identified, and if we send AT Command (basic commands), we > > get response for that.
