Hi, Regarding either writing a new driver or making changes to an exisitng one to accomodate a new chipset. Could someone point out what kind of information to look for if I capture the communication between the host and the USB device on windows??
I have two unsupported devices here: 1. Chronos Digital camera that shows up as manufactured by ViewQuest Technologies. 0x0733/0x1310 (In mass storage mode) 2. Siemens Santis USB ISDN TA. I also have a D-Link USB Modem DU-560M but not worried about that coz I use it rarely. Having used USB sniffers, I now have several MBs of logs of the communication but what communication is propreitary in there and what is generic or common to all USB devices?? Sorry if my newbie questions annoy you. I am trying to read up the 327 page USB 1.1 standard :) TIA, Siddhartha ----- Original Message ----- From: "James Courtier-Dutton" <[EMAIL PROTECTED]> To: "Siddhartha Jain" <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]> Sent: Saturday, July 19, 2003 10:42 PM Subject: Re: [linux-usb-devel] Re: [Linux-usb-users] dsc v1 problem > Siddhartha Jain wrote: > > welcome to the club of wanna-be linux-usb developers :) > > > > I am trying to do the same for my ISDN TA.
