Hi Greg, Thank you for the reply. The driver I am using is generic usb-serial driver. The devices I am using are set to a baud of 460800.
I am refreing to B9600 in the following line of "generic usb-serial" driver: usb_serial_tty_driver->init_termios.c_cflag = B9600 | CS8 | CREAD | HUPCL | CLOCAL; I wanted to know at what rate the UHCI host controller pumps the data to the device. Does that not depend on the device driver? Thanks and Regards, Sreevidya. -----Original Message----- From: Greg KH [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 27, 2006 1:37 PM To: Sreevidya Jasthy (WT01 - IP-Multimedia Carrier & Ent Networks) Cc: linux-usb-devel@lists.sourceforge.net Subject: Re: [linux-usb-devel] FW: Baud rate with usb-serial driver On Tue, Jun 27, 2006 at 01:19:07PM +0530, [EMAIL PROTECTED] wrote: > > Hi, > > I am using usb-serial driver to communicate with the CDC devices (USB > 2.0, full speed).

That depends on the type of device you attach. Some work better than others. Are you using the "generic" usb-serial driver? If so, it does not know anything about baudrates, as they do not make any sense to it. What exactly are you trying to do? thanks, greg k-h Using Tomcat but need to do more?
