I have been tasked with writing a USB driver for our embedded software to send raw data to Host. This will be used to send some logging data to host. We are using iMX31 litekit for development. From the documents that I have read on USB, my understanding is that the embedded device will be in device mode only. Also it will only be commu...

In this document, http://msdn.microsoft.com/en-us/library/aa365247(VS.85).aspx#paths To make these device objects accessible by Windows applications, the device drivers create a symbolic link (symlink) in the Win32 namespace, "Global??", to their respective device objects. For example, COM0 and COM1 under the "Global??" subdirectory ...

Hi, Our embedded systems programmer has developed the shell of a virtual serial port driver for our mobile hardware, and I have been filling in the methods to get it to work. The driver does work as expected, it simulates a COM port for a USB device that is spewing out NMEA strings (GPS data). I type WM6 for short, but the OS is WM6.1 ...
Hi, I'm currently using FindFirstFile, FindNextFile API to recursively iterate through directories for searching files based on a given criteria.

I've already asked similar question on this issue on stack overflow already, but I believe this part of the issue can be separated into a new question. I've not done mobile development before so the use of signing and certificates is a new concept to me, and for all the reading of topics I have done, its not really improved my knowledge...

Hi, This is regarding the void spin_lock_irqsave(spinlock_t *lock, unsigned long flags); function call. It is mentioned that previous interrupt state is stored in flags and we can restore them by passing this to spin_unlock_irqrestore function.
