Hello,
I am new to usb communication.i have used libusb drives to communicate with our device.device will give some response for every request.Now the problem is the device response outs coming fast in high end pc like i5,windows.
But the response time is high in core2duo or dual core pc.iam using usblyzer to check timings.I am using qsync bulk read and write.I want to know is there any dependency of system on usb. Performance.

    Please use mailing list for future support requests. Thanks.

    And yes your USB performance has dependency on system performance. Your application plays a big part. The chipset plays a big part. But the other system components like CPU, Memoery, etc also play a part.

    Take note USB Bulk Transfer is a best effort transfer and the bandwidth is not guaranteed.
