USB Debugging and Profiling Techniques - Kishon Vijay Abraham
The widespread integration of USB into embedded applications presents many developers with the challenge of debugging problems, that are difficult to detect and isolate when a USB device misbehaves. This paper discusses about the various USB debugging techniques which includes debugging at the host PC, at the device and in the cable anddiscuss when each of the above techniques will be handy. This paper will also discuss about the various facilities provided within Linux kernel to aid in USB debugging e.g sysfs, trace points etc. and the various user space tools available to help USB debugging e.g USBMON. This paper also discusses about the profiling techniques at various levels in the usb stack.This paper will be of interest to the Software Developers and Testers who develop and debug USB drivers.
I've been working in Texas Instruments for over 5 year and for over 2 years was involved in developing and debugging linux kernel device drivers for OMAP. | OMAP developed by Texas Instruments is a category of proprietary system on chips (SoCs) for portable and mobile multimedia applications. OMAP devices generally include a general-purpose ARM architecture processor core plus one or more specialized co-processors. | My latest work include developing and debugging usb2 & usb3 phy drivers and...
