Hello, I'm trying to develop software for an FX2LP chip-based USB2 board. Using libusb seemed like a convenient way to write a simple user mode software. Unfortunately I'm not getting the desired performance (max. 3Mb/sec). I was wondering, if the 1.0 version in development will tackle the problem? If been told that the issue is due to the fact that not a sufficient number of URBs are queued in one go. My C programming experience is only at college level and hints on directly accessing ioctl and usbfs seem to be quite difficult. Furthermore, since there seem only kernel header files available as documentation for those. Would installing a CVS-version of the 1.0 library offer me multiple URB/high speed transfer rates with usb_bulk_read/usb_bulk_write?
