Linux USB 2.0 Speed with OMAP-L138

Hi,

I have written a costum driver using gadgetfs with this I can only reach a Throughput of about 25Mbyte/sec and the Systemload is 30% the rest is Idle. I wonder if I would get better performance writing a kernel mode driver since the load in only 30%. What is the maximum Throughput I can get with the current Linux USB Drivers?

    Hunt,

    Can you provide more information on your custom application?

    Writing a kernel more driver would definitely boost performance and reduce cpu loading.  Depending on the application needs the throughput can be as high as 35MBps.  We can further improve on this number with further optimizations.

    regards
