Hi, I am newbie. For the better understanding of the USB, i have decided write a USB driver for the device for which it works in windows but not in linux. So i have picked the Logitech USB headset. The background i have is ,i have studied the ldd usb drivers and written few dummy USB driver. Before i start implementing, i made some basic study - on connecting the device to my Ubuntu desktop, lsusb shows Bus 002 Device 065: ID 046d:0a01 Logitech, Inc. USB Headset on issuing dmesg. [550289.589037] usb 2-1.6: new full speed USB device using ehci_hcd and address 66
That is the vendor/product ID: 046d:0a01 And then normally u will use userspace USB API to open/read the device: http://www.libusb.org/ libusb.sourceforge.net/doc/
- so i believe there should be some driver already existing, is my understanding right? - if not, where can i start for implementing a new driver of my own? I think i need start doing some reverse engineering on windows using some usb logging tool, for the understanding of working of the device
Thanks, Madav Raman
